1.1 KeyStone Architecture
TI’s KeyStone Multicore Architecture provides a high performance structure for integrating RISC and DSP cores
with application specific coprocessors and I/O. KeyStone is the first of its kind that provides adequate internal
bandwidth for nonblocking access to all processing cores, peripherals, coprocessors, and I/O. This is achieved with
four main hardware elements: Multicore Navigator, TeraNet, Multicore Shared Memory Controller, and
HyperLink.
Multicore Navigator is an innovative packet-based manager that controls 8192 queues. When tasks are allocated to
the queues, Multicore Navigator provides hardware-accelerated dispatch that directs tasks to the appropriate
available hardware. The packet-based system on a chip (SoC) uses the two Tbps capacity of the TeraNet switched
central resource to move packets. The Multicore Shared Memory Controller enables processing cores to access
shared memory directly without drawing from TeraNet’s capacity, so packet movement cannot be blocked by
memory access.
HyperLink provides a 50-Gbaud chip-level interconnect that allows SoCs to work in tandem. Its low-protocol
overhead and high throughput make HyperLink an ideal interface for chip-to-chip interconnections. Working with
Multicore Navigator, HyperLink dispatches tasks to tandem devices transparently and executes tasks as if they are
running on local resources.
1.2 Device Description
The TMS320TCI6608 DSP is a highest-performance fixed/floating-point DSP that is based on TI's KeyStone
multicore architecture. Incorporating the new and innovative C66x DSP core, this device can run at a core speed of
up to 1.25 GHz. For developers of a broad range of applications, such as mission critical, medical imaging, test and
automation, and other applications requiring high performance, TI's TMS320TCI6608 DSP offers 10 GHz
cumulative DSP and enables a platform that is power-efficient and easy to use. In addition, it is fully backward
compatible with all existing C6000 family of fixed and floating point DSPs.
TI's KeyStone architecture provides a programmable platform integrating various subsystems (C66x cores, memory
subsystem, peripherals, and accelerators) and uses several innovative components and techniques to maximize
intra-device and inter-device communication that allows the various DSP resources to operate efficiently and
seamlessly. Central to this architecture are key components such as Multicore Navigator that allows for efficient data
management between the various device components. The TeraNet is a non-blocking switch fabric enabling fast and
contention-free internal data movement. The multicore shared memory controller allows access to shared and
external memory directly without drawing from switch fabric capacity.
For fixed-point use, the C66x core has 4× the multiply accumulate (MAC) capability of C64x+ cores. In addition,
the C66x core integrates floating point capability and the per core raw computational performance is an
industry-leading 32 MACS/cycle and 16 flops/cycle. It can execute 8 single precision floating point MAC operations
per cycle and can perform double- and mixed-precision operations and is IEEE754 compliant. The C66x core
incorporates 90 new instructions (compared to the C64x+ core) targeted for floating point and vector math oriented
processing. These enhancements yield sizeable performance improvements in popular DSP kernels used in signal
processing, mathematical, and image acquisition functions. The C66x core is backwards code compatible with TI's
previous generation C6000 fixed and floating point DSP cores, ensuring software portability and shortened software
development cycles for applications migrating to faster hardware.
The TCI6608 DSP integrates a large amount of on-chip memory. In addition to 32KB of L1 program and data cache,
there is 512KB of dedicated memory per core that can be configured as mapped RAM or cache. The device also
integrates 4096KB of Multicore Shared Memory that can be used as a shared L2 SRAM and/or shared L3 SRAM. All
L2 memories incorporate error detection and error correction. For fast access to external memory, this device
includes a 64-bit DDR-3 external memory interface (EMIF) running at 1600 MHz and has ECC DRAM support.

2.2 DSP Core Description
The C66x Digital Signal Processor (DSP) extends the performance of the C64x+ and C674x DSPs through
enhancements and new features. Many of the new features target increased performance for vector processing. The
C64x+ and C674x DSPs support 2-way SIMD operations for 16-bit data and 4-way SIMD operations for 8-bit data.
On the C66x DSP, the vector processing capability is improved by extending the width of the SIMD instructions.
C66x DSPs can execute instructions that operate on 128-bit vectors. For example the QMPY32 instruction is able to
perform the element-to-element multiplication between two vectors of four 32-bit data each. The C66x DSP also
supports SIMD for floating-point operations. Improved vector processing capability (each instruction can process
multiple data in parallel) combined with the natural instruction level parallelism of C6000 architecture (e.g
execution of up to 8 instructions per cycle) results in a very high level of parallelism that can be exploited by DSP
programmers through the use of TI's optimized C/C++ compiler.
The C66x DSP consists of eight functional units, two register files, and two data paths as shown in Figure 2-1. The
two general-purpose register files (A and B) each contain 32 32-bit registers for a total of 64 registers. The
general-purpose registers can be used for data or can be data address pointers. The data types supported include
packed 8-bit data, packed 16-bit data, 32-bit data, 40-bit data, and 64-bit data. Multiplies also support 128-bit data.
40-bit-long or 64-bit-long values are stored in register pairs, with the 32 LSBs of data placed in an even register and
the remaining 8 or 32 MSBs in the next upper register (which is always an odd-numbered register). 128-bit data
values are stored in register quadruplets, with the 32 LSBs of data placed in a register that is a multiple of 4 and the
remaining 96 MSBs in the next 3 upper registers.
The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one instruction
every clock cycle. The .M functional units perform all multiply operations. The .S and .L units perform a general set
of arithmetic, logical, and branch functions. The .D units primarily load data from memory to the register file and
store results from the register file into memory.
Each C66x .M unit can perform one of the following fixed-point operations each clock cycle: four 32 × 32 bit
multiplies, sixteen 16 × 16 bit multiplies, four 16 × 32 bit multiplies, four 8 × 8 bit multiplies, four 8 × 8 bit multiplies
with add operations, and four 16 × 16 multiplies with add/subtract capabilities. There is also support for Galois field
multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and modems require
complex multiplication. Each C66x .M unit can perform one 16 × 16 bit complex multiply with or without rounding
capabilities, two 16 × 16 bit complex multiplies with rounding capability, and a 32 × 32 bit complex multiply with
rounding capability. The C66x can also perform two 16 × 16 bit and one 32 × 32 bit complex multiply instructions
that multiply a complex number with a complex conjugate of another number with rounding capability.
Communication signal processing also requires an extensive use of matrix operations. Each C66x .M unit is capable
of multiplying a [1 × 2] complex vector by a [2 × 2] complex matrix per cycle with or without rounding capability.
A version also exists allowing multiplication of the conjugate of a [1 × 2] vector with a [2 × 2] complex matrix.
Each C66x .M unit also includes IEEE floating-point multiplication operations from the C674x DSP, which includes
one single-precision multiply each cycle and one double-precision multiply every 4 cycles. There is also a
mixed-precision multiply that allows multiplication of a single-precision value by a double-precision value and an
operation allowing multiplication of two single-precision numbers resulting in a double-precision number. The
C66x DSP improves the performance over the C674x double-precision multiplies by adding a instruction allowing
one double-precision multiply per cycle and also reduces the number of delay slots from 10 down to 4. Each C66x
.M unit can also perform one the following floating-point operations each clock cycle: one, two, or four
single-precision multiplies or a complex single-precision multiply.
The .L and .S units can now support up to 64-bit operands. This allows for new versions of many of the arithmetic,
logical, and data packing instructions to allow for more parallel operations per cycle. Additional instructions were
added yielding performance enhancements of the floating point addition and subtraction instructions, including the
ability to perform one double precision addition or subtraction per cycle. Conversion to/from integer and
single-precision values can now be done on both .L and .S units on the C66x. Also, by taking advantage of the larger

SPRS623C—February 2012
operands, instructions were also added to double the number of these conversions that can be done. The .L unit also
has additional instructions for logical AND and OR instructions, as well as, 90 degree or 270 degree rotation of
complex numbers (up to two per cycle). Instructions have also been added that allow for the computing the
conjugate of a complex number.
The MFENCE instruction is a new instruction introduced on the C66x DSP. This instruction will create a DSP stall
until the completion of all the DSP-triggered memory transactions, including:
• Cache line fills
• Writes from L1D to L2 or from the CorePac to MSMC and/or other system endpoints
• Victim write backs
• Block or global coherence operations
• Cache mode changes
• Outstanding XMC prefetch requests
This is useful as a simple mechanism for programs to wait for these requests to reach their endpoint. It also provides
ordering guarantees for writes arriving at a single endpoint via multiple paths, multiprocessor algorithms that
depend on ordering, and manual coherence operations.

2.4 Boot Sequence
The boot sequence is a process by which the DSP's internal memory is loaded with program and data sections. The
DSP's internal registers are programmed with predetermined values. The boot sequence is started automatically
after each power-on reset, warm reset, and system reset. A local reset to an individual C66x CorePac should not affect
the state of the hardware boot controller on the device. For more details on the initiators of the resets, see section
7.4 ‘‘Reset Controller’’ on page 124. The bootloader uses a section of the L2 SRAM (start address 0x0087 2DC0 and
end address 0x0087 FFFF) during initial booting of the device. For more details on the type of configurations stored
in this reserved L2 section see the Bootloader for the C66x DSP User Guide in ‘‘Related Documentation from Texas
Instruments’’ on page 66.
The TCI6608 supports several boot processes that begins execution at the ROM base address, which contains the
bootloader code necessary to support various device boot modes. The boot processes are software-driven and use
the BOOTMODE[12:0] device configuration inputs to determine the software configuration that must be
completed. For more details on Boot Sequence see the Bootloader for the C66x DSP User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 66.

2.5 Boot Modes Supported and PLL Settings
The device supports several boot processes, which leverage the internal boot ROM. Most boot processes are software
driven, using the BOOTMODE[3:0] device configuration inputs to determine the software configuration that must
be completed. From a hardware perspective, there are two possible boot modes:
• Public ROM Boot - C66x CorePac0 is released from reset and begins executing from the L3 ROM base
2
address. After performing the boot process (e.g., from I C ROM, Ethernet, or RapidIO), C66x CorePac0 then
begins execution from the provided boot entry point, other C66x CorePac’s are released from reset and begin
executing an IDLE from the L3 ROM. They are then released from IDLE based on interrupts generated by
C66x CorePac0. See the Bootloader for the C66x DSP User Guide in ‘‘Related Documentation from Texas
Instruments’’ on page 66 for more details.
• Secure ROM Boot - On secure devices, the C66x CorePac0 is released from reset and begin executing from
secure ROM. Software in the secure ROM will free up internal RAM pages, after which C66x CorePac0
initiates the boot process. The C66x CorePac0 performs any authentication and decryption required on the
bootloaded image prior to beginning execution.
The boot process performed by the C66x CorePac0 in public ROM boot and secure ROM boot are determined by
the BOOTMODE[12:0] value in the DEVSTAT register. The C66x CorePac0 reads this value, and then executes the
associated boot process in software. Figure 2-2 shows the bits associated with BOOTMODE[12:0].

2.5.2.5 I C Boot Device Configuration
2.5.2.5.1 I2C Master Mode
2
In master mode, the I C device configuration uses ten bits of device configuration instead of seven as used in other
2
boot modes. In this mode, the device will make the initial read of the I C EEPROM while the PLL is in bypass mode.
The initial read will contain the desired clock multiplier, which will be set up prior to any subsequent reads.

1 The PLL boot configuration of initial silicon 1.0 may only support 800MHz, 1000MHz and 1200MHz frequencies by default.
2 The PASS PLL generates 1050 MHz and is internally divided by 3 to feed 350 MHz to the packet accelerator.
OUTPUT_DIVIDE is the value of the field of SECCTL[22:19]. This will set the PLL to the maximum clock setting
for the device (with OUTPUT_DIVIDE=2, by default).
CLK = CLKIN × (PLLM+1) ÷ (OUTPUT_DIVIDE × (PLLD+1))
The configuration for the PASS PLL is also shown. The PASS PLL is configured with these values only if the Ethernet
boot mode is selected with the input clock set to match the main PLL clock (not the PASS clock). See Table 2-3 for
details on configuring Ethernet boot mode. The output from the PASS PLL goes through an on-chip divider to
reduce the operating frequency before reaching the NETCP. The PASS PLL generates 1050 MHz, and after the chip
divider (=3), feeds 350 MHz to the NETCP.
The Main PLL is controlled using a PLL controller and a chip-level MMR. The DDR3 PLL and PASS PLL are
controlled by chip level MMRs. For details on how to set up the PLL see section 7.5 ‘‘Main PLL and PLL Controller’’
on page 131. For details on the operation of the PLL controller module, see the Phase Locked Loop (PLL) Controller
for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.
2.6 Second-Level Bootloaders
Any of the boot modes can be used to download a second-level bootloader. A second-level bootloader allows for any
level of customization to current boot methods as well as the definition of a completely customized boot.

2.8 Terminal Functions
The terminal functions table (Table 2-15) identifies the external signal names, the associated pin (ball) numbers, the
pin type (I, O/Z, or I/O/Z), whether the pin has any internal pullup/pulldown resistors, and gives functional pin
descriptions. This table is arranged by function. The power terminal functions table (Table 2-16) lists the various
power supply pins and ground pins and gives functional pin descriptions. Table 2-17 shows all pins arranged by
signal name. Table 2-18 shows all pins arranged by ball number.
There are 17 pins that have a secondary function as well as a primary function. The secondary function is indicated
with a dagger (†).
For more detailed information on device configuration, peripheral selection, multiplexed/shared pins, and
pullup/pulldown resistors, see section 3.4 ‘‘Pullup/Pulldown Resistors’’ on page 89.
Use the symbol definitions in Table 2-14 when reading Table 2-15.

Internal 100-μA pulldown or pullup is provided for this terminal. In most systems, a 1-kΩ resistor can
be used to oppose the IPD/IPU. For more detailed information on pulldown/pullup resistors and
situations in which external pulldown/pullup resistors are required, see Hardware Design Guide for
KeyStone Devices in ‘‘Related Documentation from Texas Instruments’’ on page 66.

2.9 Development and Support
2.9.1 Development Support
In case the customer would like to develop their own features and software on the TCI6608 device, TI offers an
extensive line of development tools for the TMS320C6000™ DSP platform, including tools to evaluate the
performance of the processors, generate code, develop algorithm implementations, and fully integrate and debug
software and hardware modules. The tool's support documentation is electronically available within the Code
Composer Studio™ Integrated Development Environment (IDE).
The following products support development of C6000™ DSP-based applications:
• Software Development Tools:
– Code Composer Studio™ Integrated Development Environment (IDE), including Editor C/C++/Assembly
Code Generation, and Debug plus additional development tools.
– Scalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time target software
needed to support any DSP application.
• Hardware Development Tools:
– Extended Development System (XDS™) Emulator (supports C6000™ DSP multiprocessor system debug)
– EVM (Evaluation Module)
2.9.2 Device Support
2.9.2.1 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP devices
and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS (e.g.,
TMX320CMH). Texas Instruments recommends two of three possible prefix designators for its support tools:
TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering
prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow:
• TMX: Experimental device that is not necessarily representative of the final device's electrical specifications
• TMP: Final silicon die that conforms to the device's electrical specifications but has not completed quality and
reliability verification
• TMS: Fully qualified production device
Support tool development evolutionary flow:
• TMDX: Development-support product that has not yet completed Texas Instruments internal qualification
testing.
• TMDS: Fully qualified development-support product
TMX and TMP devices and TMDX development-support tools are shipped with the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS devices and TMDS development-support tools have been characterized fully, and the quality and reliability of
the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard production
devices. Texas Instruments recommends that these devices not be used in any production system because their
expected end-use failure rate still is undefined. Only qualified production devices are to be used.

3 Device Configuration
On the TMS320TCI6608 device, certain device configurations like boot mode and endianess, are selected at device
power-on reset. The status of the peripherals (enabled/disabled) is determined after device power-on reset.
3.1 Device Configuration at Device Reset
Table 3-1 describes the device configuration pins. The logic level is latched at power-on reset to determine the device
configuration. The logic level on the device configuration pins can be set by using external pullup/pulldown resistors
or by using some control device (e.g., FPGA/CPLD) to intelligently drive these pins. When using a control device,
care should be taken to ensure there is no contention on the lines when the device is out of reset. The device
configuration pins are sampled during power-on reset and are driven after the reset is removed. To avoid
contention, the control device must stop driving the device configuration pins of the DSP. And when driving by a
control device, the control device must be fully powered and out of reset itself and driving the pins before the DSP
can be taken out of reset.
Also, please note that most of the device configuration pins are shared with other function pins
(LENDIAN/GPIO[0], BOOTMODE[12:0]/GPIO[13:1], PCIESSMODE[1:0]/GPIO[15:14] and PCIESSEN/TIMI0),
some time must be given following the rising edge of reset in order to drive these device configuration input pins
before they assume an output state (those GPIO pins should not become outputs during boot). Another caution that
needs to be noted is that systems using TIMI0 (pin shared with PCIESSEN) as a clock input must assure that the
clock itself is disabled from the input until after reset is released and a control device is no longer driving that input.
Note—If a configuration pin must be routed out from the device and it is not driven (Hi-Z state), the internal
pullup/pulldown (IPU/IPD) resistor should not be relied upon. TI recommends the use of an external
pullup/pulldown resistor. For more detailed information on pullup/pulldown resistors and situations in
which external pullup/pulldown resistors are required, see Section 3.4 ‘‘Pullup/Pulldown Resistors’’ on
page 89.

3.2 Peripheral Selection After Device Reset
Several of the peripherals on the TMS320TCI6608 are controlled by the Power Sleep Controller (PSC). By default,
the PCIe, SRIO, and HyperLink are held in reset and clock-gated. The memories in these modules are also in a
low-leakage sleep mode. Software is required to turn these memories on. The software enables the modules (turns
on clocks and de-asserts reset) before these modules can be used.
If one of the above modules is used in the selected ROM boot mode, the ROM code will automatically enable the
module.
All other modules come up enabled by default and there is no special software sequence to enable. For more detailed
information on the PSC usage, see the Power Sleep Controller (PSC) for KeyStone Devices User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 66.
3.3 Device State Control Registers
The TMS320TCI6608 device has a set of registers that are used to provide the status or configure certain parts of its
peripherals. These registers are shown in Table 3-2.

3.3.4 Kicker Mechanism (KICK0 and KICK1) Register
The Bootcfg module contains a kicker mechanism to prevent any spurious writes from changing any of the Bootcfg
MMR values. When the kicker is locked (which it is initially after power on reset) none of the Bootcfg MMRs are
writable (they are only readable). This mechanism requires two MMR writes to the KICK0 and KICK1 registers with
exact data values before the kicker lock mechanism is un-locked. See Table 3-2 ‘‘Device State Control Registers’’ on
page 68 for the address location. Once released then all the Bootcfg MMRs having “write” permissions are writable
(the read only MMRs are still read only). The first KICK0 data is 0x83e70b13. The second KICK1 data is 0x95a4f1e0.
Writing any other data value to either of these kick MMRs will lock the kicker mechanism and block any writes to
Bootcfg MMRs.
The kicker mechanism is unlocked by the ROM code. Do not write any other different values afterward to these
registers because that will lock the kicker mechanism and block any writes to Bootcfg registers.
3.3.5 LRESETNMI PIN Status (LRSTNMIPINSTAT) Register
The LRSTNMIPINSTAT Register is created in Boot Configuration to latch the status of LRESET and NMI based on
CORESEL. The LRESETNMI PIN Status Register is shown in Figure 3-4 and described in Table 3-6.

3.3.7 Reset Status (RESET_STAT) Register
The reset status register (RESET_STAT) captures the status of Local reset (LRx) for each of the cores and also the
global device reset (GR). Software can use this information to take different device initialization steps, if desired.
• In case of Local reset: The LRx bits are written as 1 and GR bit is written as 0 only when the CorePac receives
an local reset without receiving a global reset.
• In case of Global reset: The LRx bits are written as 0 and GR bit is written as 1 only when a global reset is
asserted.
The Reset Status Register is shown in Figure 3-6 and described in Table 3-8.

The BCx bit indicates the boot complete status of the corresponding core. All BCx bits will be sticky bits — that is
they can be set only once by the software after device reset and they will be cleared to 0 on all device resets.
Boot ROM code will be implemented such that each core will set its corresponding BCx bit immediately before
branching to the predefined location in memory.

NMIGRx registers are used for generating NMI events to the corresponding CorePac. The TCI6608 has
eight NMIGRx registers (NMIGR0 through NMIGR7). The NMIGR0 register generates an NMI event to CorePac0,
the NMIGR1 register generates an NMI event to CorePac1, and so on. Writing a 1 to the NMIG field generates a
NMI pulse. Writing a 0 has no effect and reads return 0 and have no other effect. The NMI Even Generation to

3.3.12 IPC Generation (IPCGRx) Registers
IPCGRx are the IPC interrupt generation registers to facilitate inter CorePac interrupts.
The TCI6608 has eight IPCGRx registers (IPCGR0 through IPCGR7). These registers can be used by external hosts
or CorePacs to generate interrupts to other CorePacs. A write of 1 to IPCG field of IPCGRx register will generate an
interrupt pulse to CorePacx (0 <= x <= 7).
These registers also provide a Source ID facility by which up to 28 different sources of interrupts can be identified.
Allocation of source bits to source processor and meaning is entirely based on software convention. The register field
descriptions are given in the following tables. Virtually anything can be a source for these registers as this is
completely controlled by software. Any master that has access to BOOTCFG module space can write to these
registers. The IPC Generation Register is shown in Figure 3-11 and described in Table 3-13.

3.3.14 IPC Generation Host (IPCGRH) Register
IPCGRH register is provided to facilitate host DSP interrupt. Operation and use of IPCGRH is the same as
other IPCGR registers. Interrupt output pulse created by IPCGRH is driven on a device pin, host interrupt/event
output (HOUT).
The host interrupt output pulse should be stretched. It should be asserted for 4 bootcfg clock cycles (CPU/6)
followed by a deassertion of 4 bootcfg clock cycles. Generating the pulse will result in 8 CPU/6 cycle pulse blocking
window. Write to IPCGRH with IPCG bit (bit 0) set will only generate a pulse if they are beyond 8 CPU/6 cycle
period. The IPC Generation Host Register is shown in Figure 3-13 and described in Table 3-15.

3.4 Pullup/Pulldown Resistors
Proper board design should ensure that input pins to the device always be at a valid logic level and not floating. This
may be achieved via pullup/pulldown resistors. The device features internal pullup (IPU) and internal pulldown
(IPD) resistors on most pins to eliminate the need, unless otherwise noted, for external pullup/pulldown resistors.
An external pullup/pulldown resistor needs to be used in the following situations:
• Device Configuration Pins: If the pin is both routed out and are not driven (in Hi-Z state), an external
pullup/pulldown resistor must be used, even if the IPU/IPD matches the desired value/state.
• Other Input Pins: If the IPU/IPD does not match the desired value/state, use an external pullup/pulldown
resistor to pull the signal to the opposite rail.
For the device configuration pins (listed in Table 3-1), if they are both routed out and are not driven (in Hi-Z state),
it is strongly recommended that an external pullup/pulldown resistor be implemented. Although, internal
pullup/pulldown resistors exist on these pins and they may match the desired configuration value, providing
external connectivity can help ensure that valid logic levels are latched on these device configuration pins. In
addition, applying external pullup/pulldown resistors on the device configuration pins adds convenience to the user
in debugging and flexibility in switching operating modes.
Tips for choosing an external pullup/pulldown resistor:
• Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure to
include the leakage currents of all the devices connected to the net, as well as any internal pullup or pulldown
resistors.
• Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of all inputs
connected to the net. For a pullup resistor, this should be above the highest VIH level of all inputs on the net.
A reasonable choice would be to target the VOL or VOH levels for the logic family of the limiting device; which,
by definition, have margin to the VIL and VIH levels.
• Select a pullup/pulldown resistor with the largest possible value that can still ensure that the net will reach the
target pulled value when maximum current from all devices on the net is flowing through the resistor. The
current to be considered includes leakage current plus, any other internal and external pullup/pulldown
resistors on the net.
• For bidirectional nets, there is an additional consideration that sets a lower limit on the resistance value of the
external resistor. Verify that the resistance is small enough that the weakest output buffer can drive the net to
the opposite logic level (including margin).
• Remember to include tolerances when selecting the resistor value.
• For pullup resistors, also remember to include tolerances on the DVDD rail.
For most systems:
• A 1-kΩ resistor can be used to oppose the IPU/IPD while meeting the above criteria. Users should confirm this
resistor value is correct for their specific application.
• A 20-kΩ resistor can be used to compliment the IPU/IPD on the device configuration pins while meeting the
above criteria. Users should confirm this resistor value is correct for their specific application.
For more detailed information on input current (II), and the low-level/high-level input voltages (VIL and VIH) for
the TMS320TCI6608 device, see Section 6.3 ‘‘Electrical Characteristics’’ on page 110.
To determine which pins on the device include internal pullup/pulldown resistors, see Table 2-15 ‘‘Terminal
Functions — Signals and Control by Function’’ on page 40.

4 System Interconnect
On the TMS320TCI6608 device, the C66x CorePacs, the EDMA3 transfer controllers, and the system peripherals
are interconnected through the TeraNet, which is a non-blocking switch fabric enabling fast and contention-free
internal data movement. The TeraNet allows for low-latency, concurrent data transfers between master peripherals
and slave peripherals. The TeraNet also allows for seamless arbitration between the system masters when accessing
system slaves.
4.1 Internal Buses and Switch Fabrics
Two types of buses exist in the device: data buses and configuration buses. Some peripherals have both a data bus
and a configuration bus interface, while others have only one type of interface. Further, the bus interface width and
speed varies from peripheral to peripheral. Configuration buses are mainly used to access the register space of a
peripheral and the data buses are used mainly for data transfers.
The C66x CorePacs, the EDMA3 traffic controllers, and the various system peripherals can be classified into two
categories: masters and slaves. Masters are capable of initiating read and write transfers in the system and do not rely
on the EDMA3 for their data transfers. Slaves, on the other hand, rely on the masters to perform transfers to and
from them. Examples of masters include the EDMA3 traffic controllers, SRIO, and Network Coprocessor packet
2
DMA. Examples of slaves include the SPI, UART, and I C.
The masters and slaves in the device are communicating through the TeraNet (switch fabric). The device contains
two switch fabrics. The data switch fabric (data TeraNet) and the configuration switch fabric (configuration
TeraNet). The data TeraNet, is a high-throughput interconnect mainly used to move data across the system. The
data TeraNet connects masters to slaves via data buses. Some peripherals require a bridge to connect to the data
TeraNet. The configuration TeraNet, is mainly used to access peripheral registers. The configuration TeraNet
connects masters to slaves via configuration buses. As with the data TeraNet, some peripherals require the use of a
bridge to interface to the configuration TeraNet. Note that the data TeraNet also connects to the configuration
TeraNet. For more details see 4.2 ‘‘Switch Fabric Connections’’.

4.3 Bus Priorities
The priority level of all master peripheral traffic is defined at the TeraNet boundary. User programmable priority
registers allow software configuration of the data traffic through the TeraNet. Note that a lower number means
higher priority - PRI = 000b = urgent, PRI = 111b = low.
All other masters provide their priority directly and do not need a default priority setting. Examples include the
CorePacs, whose priorities are set through software in the UMC control registers. All the packet-DMA-based
peripherals also have internal registers to define the priority level of their initiated transactions.
The packet DMA secondary port is one master port that does not have priority allocation register inside the IP. The
priority level for transaction from this master port is described by PKTDMA_PRI_ALLOC register in Figure 4-5 and
Table 4-4.

5.1 Memory Architecture
Each C66x CorePac of the TMS320TCI6608 device contains a 512KB level-2 memory (L2), a 32KB level-1 program
memory (L1P), and a 32KB level-1 data memory (L1D). The device also contain a 4096KB multicore shared memory
(MSM). All memory on the TCI6608 has a unique location in the memory map (see Table 2-2 ‘‘Memory Map
Summary’’ on page 21.
After device reset, L1P and L1D cache are configured as all cache, by default. The L1P and L1D cache can be
reconfigured via software through the L1PMODE field of the L1P Configuration Register (L1PCFG) and the
L1DMODE field of the L1D Configuration Register (L1DCFG) of the C66x CorePac. L1D is a two-way
set-associative cache, while L1P is a direct-mapped cache.
The on-chip bootloader changes the reset configuration for L1P and L1D. For more information, see the Bootloader
for the C66x DSP User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.
For more information on the operation L1 and L2 caches, see the C66x DSP Cache User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 66.
5.1.1 L1P Memory
The L1P memory configuration for the TCI6608 device is as follows:

5.1.3 L2 Memory
The L2 memory configuration for the TCI6608 device is as follows:
• Total memory size is 4096KB
• Each core contains 512KB of memory
• Local starting address for each core is 0080 0000h
L2 memory can be configured as all SRAM, all 4-way set-associative cache, or a mix of the two. The amount of L2
memory that is configured as cache is controlled through the L2MODE field of the L2 Configuration Register
(L2CFG) of the C66x CorePac. Figure 5-4 shows the available SRAM/cache configurations for L2. By default, L2 is
configured as all SRAM after device reset.

Global addresses are accessible to all masters in the system. In addition, local memory can be accessed directly by
the associated processor through aliased addresses, where the eight MSBs are masked to zero. The aliasing is handled
within the C66x CorePac and allows for common code to be run unmodified on multiple cores. For example, address
location 0x10800000 is the global base address for C66x CorePac Core 0's L2 memory. C66x CorePac Core 0 can
access this location by either using 0x10800000 or 0x00800000. Any other master on the device must use 0x10800000
only. Conversely, 0x00800000 can by used by any of the cores as their own L2 base addresses.
For C66x CorePac Core 0, as mentioned, this is equivalent to 0x10800000, for C66x CorePac Core 1 this is equivalent
to 0x11800000, and for C66x CorePac Core 2 this is equivalent to 0x12800000. Local addresses should be used only
for shared code or data, allowing a single image to be included in memory. Any code/data targeted to a specific core,
or a memory region allocated during run-time by a particular core should always use the global address only.

5.1.4 MSM SRAM
The MSM SRAM configuration for the TCI6608 device is as follows:
• Memory size is 4096KB
• The MSM SRAM can be configured as shared L2 and/or shared L3 memory
• Allows extension of external addresses from 2GB to up to 8GB
• Has built in memory protection features
The MSM SRAM is always configured as all SRAM. When configured as a shared L2, its contents can be cached in
L1P and L1D. When configured in shared L3 mode, it’s contents can be cached in L2 also. For more details on
external memory address extension and memory protection features, see the Multicore Shared Memory Controller
(MSMC) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.
5.1.5 L3 Memory
The L3 ROM on the device is 128KB. The ROM contains software used to boot the device. There is no requirement
to block accesses from this portion to the ROM.

5.2 Memory Protection
Memory protection allows an operating system to define who or what is authorized to access L1D, L1P, and L2
memory. To accomplish this, the L1D, L1P, and L2 memories are divided into pages. There are 16 pages of L1P (2KB
each), 16 pages of L1D (2KB each), and 32 pages of L2 (16KB each). The L1D, L1P, and L2 memory controllers in
the C66x CorePac are equipped with a set of registers that specify the permissions for each memory page.
Each page may be assigned with fully orthogonal user and supervisor read, write, and execute permissions. In
addition, a page may be marked as either (or both) locally accessible or globally accessible. A local access is a direct
DSP access to L1D, L1P, and L2, while a global access is initiated by a DMA (either IDMA or the EDMA3) or by
other system masters. Note that EDMA or IDMA transfers programmed by the DSP count as global accesses. On a
secure device, pages can be restricted to secure access only (default) or opened up for public, non-secure access.
The DSP and each of the system masters on the device are all assigned a privilege ID. It is possible to specify whether
memory pages are locally or globally accessible.
The AIDx and LOCAL bits of the memory protection page attribute registers specify the memory page protection
scheme, see Table 5-1.
Table 5-1
Available Memory Page Protection Schemes
AIDx Bit

Description

No access to memory page is permitted.

0
Only accesses by system masters and IDMA are permitted (includes EDMA and IDMA accesses initiated by the DSP).
1
1
All accesses permitted.
End of Table 5-1
Faults are handled by software in an interrupt (or an exception, programmable within the C66x CorePac interrupt
controller) service routine. A DSP or DMA access to a page without the proper permissions will:
• Block the access — reads return zero, writes are ignored
• Capture the initiator in a status register — ID, address, and access type are stored
• Signal event to DSP interrupt controller
The software is responsible for taking corrective action to respond to the event and resetting the error status in the
memory controller. For more information on memory protection for L1D, L1P, and L2, see the C66x CorePac User
Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.

5.3 Bandwidth Management
When multiple requestors contend for a single C66x CorePac resource, the conflict is resolved by granting access to
the highest priority requestor. The following four resources are managed by the Bandwidth Management control
hardware:
• Level 1 Program (L1P) SRAM/Cache
• Level 1 Data (L1D) SRAM/Cache
• Level 2 (L2) SRAM/Cache
• Memory-mapped registers configuration bus
The priority level for operations initiated within the C66x CorePac are declared through registers in the C66x
CorePac. These operations are:
• DSP-initiated transfers
• User-programmed cache coherency operations
• IDMA-initiated transfers
The priority level for operations initiated outside the C66x CorePac by system peripherals is declared through the
Priority Allocation Register (PRI_ALLOC), see section 4.3 ‘‘Bus Priorities’’ on page 99 for more details. System
peripherals with no fields in the PRI_ALLOC have their own registers to program their priorities.
More information on the bandwidth management features of the C66x CorePac can be found in the C66x CorePac
User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.
5.4 Power-Down Control
The C66x CorePac supports the ability to power down various parts of the C66x CorePac. The power down
controller (PDC) of the C66x CorePac can be used to power down L1P, the cache control hardware, the DSP, and
the entire C66x CorePac. These power-down features can be used to design systems for lower overall system power
requirements.
Note—The TCI6608 does not support power-down modes for the L2 memory at this time.
More information on the power-down features of the C66x CorePac can be found in the TMS320C66x CorePac
Reference Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.2.1 Power-Supply Sequencing
This section defines the requirements for a power up sequencing from a power-on reset condition. There are two
acceptable power sequences for the device. The first sequence stipulates the core voltages starting before the IO
voltages as shown below.
1. CVDD
2. CVDD1, VDDT1-3
3. DVDD18, AVDD1, AVDD2
4. DVDD15, VDDR1-4
The second sequence provides compatibility with other TI processors with the IO voltage starting before the core
voltages as shown below.
1. DVDD18, AVDD1, AVDD2
2. CVDD
3. CVDD1, VDDT1-3
4. DVDD15, VDDR1-4
The clock input buffers for CORECLK, DDRCLK, PASSCLK, SRIOSGMIICLK, PCIECLK and MCMCLK
use CVDD as a supply voltage. These clock inputs are not failsafe and must be held in a high-impedance state until
CVDD is at a valid voltage level. Driving these clock inputs high before CVDD is valid could cause damage to the
device. Once CVDD is valid it is acceptable that the P and N legs of these CLKs may be held in a static state (either
high and low or low and high) until a valid clock frequency is needed at that input. To avoid internal oscillation the
clock inputs should be removed from the high impedance state shortly after CVDD is present.
If a clock input is not used it must be held in a static state. To accomplish this the N leg should be pulled to ground
through a 1K ohm resistor. The P leg should be tied to CVDD to ensure it won't have any voltage present until
CVDD is active. Connections to the IO cells powered by DVDD18 and DVDD15 are not failsafe and should not be
driven high before these voltages are active. Driving these IO cells high before DVDD18 or DVDD15 are valid could
cause damage to the device.
The device initialization is broken into two phases. The first phase consists of the time period from the activation of
the first power supply until the point in which all supplies are active and at a valid voltage level. Either of the
sequencing scenarios described above can be implemented during this phase. The figures below show both the
core-before-IO voltage sequence and the IO-before-core voltage sequence. POR must be held low for the entire
power stabilization phase.
This is followed by the device initialization phase. The rising edge of POR followed by the rising edge of RESETFULL
will trigger the end of the initialization phase but both must be inactive for the initialization to complete. POR must
always go inactive before RESETFULL goes inactive as described below. SYSCLK1 in the following section refers to
the clock that is used by the CorePac, see Figure 7-7 for more details.

7.2.1.1 Core-Before-IO Power Sequencing
Figure 7-1 shows the power sequencing and reset control of TMS320TCI6608 for device initialization. POR may be
removed after the power has been stable for the required 100 μsec. RESETFULL must be held low for a period after
the rising edge of POR but may be held low for longer periods if necessary. The configuration bits shared with the
GPIO pins will be latched on the rising edge of RESETFULL and must meet the setup and hold times specified.
SYSCLK1 must always be active before POR can be removed. Core-before-IO power sequencing is defined in
Table 7-2.
Note—TI recommends a maximum of 100 ms between one power rail being valid, and the next power rail
in the sequence starting to ramp

1
Begin Power Stabilization Phase
• CVDD (core AVS) ramps up.
• POR must be held low through the power stabilization phase. Because POR is low, all the core logic that has async reset (created from
POR) is put into the reset state.
2a
• CVDD1 (core constant) ramps at the same time or shortly following CVDD. Although ramping CVDD1 and CVDD simultaneously is
permitted, the voltage for CVDD1 must never exceed CVDD until after CVDD has reached a valid voltage.
• The purpose of ramping up the core supplies close to each other is to reduce crowbar current. CVDD1 should trail CVDD as this will
ensure that the WLs in the memories are turned off and there is no current through the memory bit cells. If, however, CVDD1 (core
constant) ramps up before CVDD (core AVS), then the worst-case current could be on the order of twice the specified draw of CVDD1.
2b
• Once CVDD is valid, the clock drivers should be enabled. Although the clock inputs are not necessary at this time, they should either be
driven with a valid clock or be held in a static state with one leg high and one leg low.
2c
• The DDRCLK and SYSCLK1 may begin to toggle anytime between when CVDD is at a valid level and the setup time before POR goes high
specified by t6.
3
• Filtered versions of 1.8 V can ramp simultaneously with DVDD18.
• RESETSTAT is driven low once the DVDD18 supply is available.
• All LVCMOS input and bidirectional pins must not be driven or pulled high until DVDD18 is present. Driving an input or bidirectional pin
before DVDD18 is valid could cause damage to the device.
4a
• DVDD15 (1.5 V) supply is ramped up following DVDD18. Although ramping DVDD18 and DVDD15 simultaneously is permitted, the
voltage for DVDD15 must never exceed DVDD18.
4b
• RESET may be driven high any time after DVDD18 is at a valid level. In a POR-controlled boot, RESET must be high before POR is driven
high.
5
• POR must continue to remain low for at least 100 μs after power has stabilized.
End Power Stabilization Phase
6
• Device initialization requires 500 SYSCLK1 periods after the Power Stabilization Phase. The maximum clock period is 33.33 nsec, so a delay
of an additional 16 μs is required before a rising edge of POR. The clock must be active during the entire 16 μs.
7
• RESETFULL must be held low for at least 24 transitions of the SYSCLK1 after POR has stabilized at a high level.
8
• The rising edge of the RESETFULL will remove the reset to the efuse farm allowing the scan to begin.
• Once device initialization and the efuse farm scan are complete, the RESETSTAT signal is driven high. This delay will be 10000 to 50000
clock cycles.
End Device Initialization Phase
9
• GPIO configuration bits must be valid for at least 12 transitions of the SYSCLK1 before the rising edge of RESETFULL
10
• GPIO configuration bits must be held valid for at least 12 transitions of the SYSCLK1 after the rising edge of RESETFULL

End Device Initialization Phase
End of Table 7-3
7.2.1.3 Prolonged Resets
Holding the device in POR, RESETFULL, or RESET for long periods of time will affect the long term reliability of
the part. The device should not be held in a reset for times exceeding one hour and should not be held in reset for
more the 5% of the time during which power is applied. Exceeding these limits will cause a gradual reduction in the
reliability of the part. This can be avoided by allowing the DSP to boot and then configuring it to enter a hibernation
state soon after power is applied. This will satisfy the reset requirement while limiting the power consumption of the
device.
7.2.1.4 Clocking During Power Sequencing
Some of the clock inputs are required to be present for the device to initialize correctly, but behavior of many of the
clocks is contingent on the state of the boot configuration pins. Table 7-4 describes the clock sequencing and the
conditions that affect the clock operation. Note that all clock drivers should be in a high-impedance state until
CVDD is at a valid level and that all clock inputs either be active or in a static state with one leg pulled low and the
other connected to CVDD.

7.2.2 Power-Down Sequence
The power down sequence is the exact reverse of the power-up sequence described above. The goal is to prevent a
large amount of static current and to prevent overstress of the device. A power-good circuit that monitors all the
supplies for the device should be used in all designs. If a catastrophic power supply failure occurs on any voltage rail,
POR should transition to low to prevent over-current conditions that could possibly impact device reliability.
A system power monitoring solution is needed to shut down power to the board if a power supply fails. Long-term
exposure to an environment in which one of the power supply voltages is no longer present will affect the reliability
of the device. Holding the device in reset is not an acceptable solution because prolonged periods of time with an
active reset can also affect long term reliability.
7.2.3 Power Supply Decoupling and Bulk Capacitors
In order to properly decouple the supply planes on the PCB from system noise, decoupling and bulk capacitors are
required. Bulk capacitors are used to minimize the effects of low frequency current transients and decoupling or
bypass capacitors are used to minimize higher frequency noise. For recommendations on selection of Power Supply
Decoupling and Bulk capacitors see the Hardware Design Guide for KeyStone Devices in ‘‘Related Documentation
from Texas Instruments’’ on page 66.

7.2.4 SmartReflex
Increasing the device complexity increases its power consumption and with the smaller transistor structures
responsible for higher achievable clock rates and increased performance, comes an inevitable penalty, increasing the
leakage currents. Leakage currents are present in any active circuit, independently of clock rates and usage scenarios.
This static power consumption is mainly determined by transistor type and process technology. Higher clock rates
also increase dynamic power, the power used when transistors switch. The dynamic power depends mainly on a
specific usage scenario, clock rates, and I/O activity.
Texas Instruments' SmartReflex technology is used to decrease both static and dynamic power consumption while
maintaining the device performance. SmartReflex in the TMS320TCI6608 device is a feature that allows the core
voltage to be optimized based on the process corner of the device. This requires a voltage regulator for each
TMS320TCI6608 device.
To guarantee maximizing performance and minimizing power consumption of the device, SmartReflex is required
to be implemented whenever the TMS320TCI6608 device is used. The voltage selection is done using 4 VCNTL pins
which are used to select the output voltage of the core voltage regulator.
For information on implementation of SmartReflex see the Power Management for KeyStone Devices application
report and the Hardware Design Guide for KeyStone Devices in ‘‘Related Documentation from Texas Instruments’’
on page 66.

7.3 Power Sleep Controller (PSC)
The Power Sleep Controller (PSC) controls overall device power by turning off unused power domains and gating
off clocks to individual peripherals and modules. The PSC provides the user with an interface to control several
important power and clock operations.
For information on the Power Sleep Controller, see the Power Sleep Controller (PSC) for KeyStone Devices User
Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.
7.3.1 Power Domains
The device has several power domains that can be turned on for operation or off to minimize power dissipation. The
global power/sleep controller (GPSC) is used to control the power gating of various power domains.

7.3.2 Clock Domains
Cock gating to each logic block is managed by the local power/sleep controllers (LPSCs) of each module. For
modules with a dedicated clock or multiple clocks, the LPSC communicates with the PLL controller to enable and
disable that module's clock(s) at the source. For modules that share a clock with other modules, the LPSC controls
the clock gating.

7.4 Reset Controller
The reset controller detects the different type of resets supported on the TMS320TCI6608 device and manages the
distribution of those resets throughout the device.
The device has several types of resets:
• Power-on reset
• Hard reset
• Soft reset
• CPU local reset
Table 7-9 explains further the types of reset, the reset initiator, and the effects of each reset on the device. For more
information on the effects of each reset on the PLL controllers and their clocks, see Section ‘‘Reset Electrical Data /
Timing’’ on page 129

7.4.1 Power-on Reset
Power-on reset is used to reset the entire device, including the test and emulation logic.
Power-on reset is initiated by the following
1. POR pin
2. RESETFULL pin
During power-up, the POR pin must be asserted (driven low) until the power supplies have reached their normal
operating conditions. A RESETFULL pin is also provided to allow the on-board host to reset the entire device
including the reset isolated logic. The assumption is that, device is already powered up and hence unlike POR,
RESETFULL pin will be driven by the on-board host control other than the power good circuitry. For power-on
reset, the Main PLL Controller comes up in bypass mode and the PLL is not enabled. Other resets do not affect the
state of the PLL or the dividers in the PLL controller.
The following sequence must be followed during a power-on reset:
1. Wait for all power supplies to reach normal operating conditions while keeping the POR pin asserted (driven
low). While POR is asserted, all pins except RESETSTAT will be set to high-impedance. After the POR pin is
de-asserted (driven high), all Z group pins, low group pins, and high group pins are set to their reset state and
will remain at their reset state until otherwise configured by their respective peripheral. All peripherals that are
power managed, are disabled after a Power-on Reset and must be enabled through the Device State Control
registers (for more details, see Section Table 3-2 ‘‘Device State Control Registers’’ on page 68).
2. Clocks are reset, and they are propagated throughout the chip to reset any logic that was using reset
synchronously. All logic is now reset and RESETSTAT will be driven low indicating that the device is in reset.
3. POR must be held active until all supplies on the board are stable then for at least an additional time for the
Chip level PLLs to lock.
4. The POR pin can now be de-asserted. Reset sampled pin values are latched at this point. The Chip level PLLs
is taken out of reset and begins its locking sequence, and all power-on device initialization also begins.
5. After device initialization is complete, the RESETSTAT pin is de-asserted (driven high). By this time, DDR3
PLL has already completed its locking sequence and is outputting a valid clock. The system clocks of both PLL
controllers are allowed to finish their current cycles and then paused for 10 cycles of their respective system
reference clocks. After the pause, the system clocks are restarted at their default divide by settings.
6. The device is now out of reset and device execution begins as dictated by the selected boot mode.
Note—To most of the device, reset is de-asserted only when the POR and RESET pins are both de-asserted
(driven high). Therefore, in the sequence described above, if the RESET pin is held low past the low period
of the POR pin, most of the device will remain in reset. The RESET pin should not be tied together with the
POR pin.

7.4.2 Hard Reset
A hard reset will reset everything on the device except the PLLs, test, emulation logic, and reset isolation modules.
POR should also remain de-asserted during this time.
Hard reset is initiated by the following
• RESET pin
• RSCTRL register in PLLCTL
• Watchdog timer
• Emulation
All the above initiators by default are configured to act as hard reset. Except emulation, all the other 3 initiators can
be configured as Soft resets in the RSCFG register in PLLCTL.
The following sequence must be followed during a Hard reset:
1. The RESET pin is pulled active low for a minimum of 24 CLKIN1 cycles. During this time the RESET signal is
able to propagate to all modules (except those specifically mentioned above). All I/O are Hi-Z for modules
affected by RESET, to prevent off-chip contention during the warm reset.
2. Once all logic is reset, RESETSTAT is driven active to denote that the device is in reset.
3. The RESET pin can now be released. A minimal device initialization begins to occur. Note that configuration
pins are not re-latched and clocking is unaffected within the device.
4. After device initialization is complete, the RESETSTAT pin is de-asserted (driven high).
Note—The POR pin should be held inactive (high) throughout the warm reset sequence. Otherwise, if POR
is activated (brought low), the minimum POR pulse width must be met. The RESET pin should not be tied
together with the POR pin.

7.4.3 Soft Reset
A soft reset will behave like a hard reset except that the PCIe MMRs and DDR3 EMIF MMRs content is retained.
POR should also remain de-asserted during this time.
Soft reset is initiated by the following
• RESET pin
• RSCTRL register in PLLCTL
• Watchdog timer
All the above initiators by default are configured to act as hard reset. Except emulation, all the other 3 initiators can
be configured as soft resets in the RSCFG register in PLLCTL.
In the case of a soft reset, the clock logic or the power control logic of the peripherals are not affected, and, therefore,
the enabled/disabled state of the peripherals is not affected. On a soft reset, the DDR3 memory controller registers
are not reset. In addition, the DDR3 SDRAM memory content is retained if the user places the DDR3 SDRAM in
self-refresh mode before invoking the soft reset.
During a soft reset, the following happens:
1. The RESETSTAT pin goes low to indicate an internal reset is being generated. The reset is allowed to propagate
through the system. Internal system clocks are not affected. PLLs also remain locked.
2. After device initialization is complete, the RESETSTAT pin is deasserted (driven high). In addition, the PLL
controllers pause their system clocks for about 8 cycles.
At this point:
› The state of the peripherals before the soft reset is not changed.
› The I/O pins are controlled as dictated by the DEVSTAT register.
› The DDR3 MMRs and PCIe MMRs retain their previous values. Only the DDR3 Memory Controller
and PCIe state machines are reset by the soft reset.
› The PLL controllers are operating in the mode prior to soft reset. System clocks are unaffected.
The boot sequence is started after the system clocks are restarted. Since the configuration pins are not latched with
a System Reset, the previous values, as shown in the DEVSTAT register, are used to select the boot mode.

7.4.4 Local Reset
The local reset can be used to reset a particular CorePac without resetting any other chip components.
Local reset is initiated by the following (for more details see the Phase Locked Loop (PLL) Controller for KeyStone
Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66:
• LRESET pin
• Watchdog timer should cause one of the below based on the setting of the CORESEL[2:0] and RSTCFG
register in the PLL controller. See ‘‘Reset Configuration Register (RSTCFG)’’ on page 139 and ‘‘CIC Registers’’
on page 174:
– Local Reset
– NMI
– NMI followed by a time delay and then a local reset for the CorePac selected
– Hard Reset by requesting reset via PLLCTL
• LPSC MMRs (memory-mapped registers)
7.4.5 Reset Priority
If any of the above reset sources occur simultaneously, the PLLCTL processes only the highest priority reset request.
The reset request priorities are as follows (high to low):
• Power-on reset
• Hard/Soft reset
7.4.6 Reset Controller Register
The reset controller register are part of the PLLCTL MMRs. All TCI6608 device-specific MMRs are covered in
Section 7.5.3 ‘‘Main PLL Control Register’’ on page 140. For more details on these registers and how to program
them, see the Phase Locked Loop (PLL) Controller for KeyStone Devices User Guide in ‘‘Related Documentation from
Texas Instruments’’ on page 66.

7.5 Main PLL and PLL Controller
This section provides a description of the Main PLL and the PLL controller. For details on the operation of the PLL
controller module, see the Phase Locked Loop (PLL) Controller for KeyStone Devices User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 66.
The Main PLL is controlled by the standard PLL controller. The PLL controller manages the clock ratios, alignment,
and gating for the system clocks to the device. Figure 7-7 shows a block diagram of the main PLL and the PLL
controller.

www.ti.com
Note—The Main PLL Controller registers can be accessed by any master in the device. The PLLM[5:0] bits
of the multiplier are controlled by the PLLM register inside the PLL controller and PLLM[12:6] bits are
controlled by the chip-level MAINPLLCTL0 register. The Output Divide and Bypass logic of the PLL are
controlled by fields in the SECCTL register in the PLL controller. Only PLLDIV2, PLLDIV5, and PLLDIV8
are programmable on the TCI6608 device. See the Phase Locked Loop (PLL) Controller for KeyStone
Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66 for more details on
how to program the PLL controller.
The multiplication and division ratios within the PLL and the post-division for each of the chip-level clocks are
determined by a combination of this PLL and the PLL Controller. The PLL controller also controls reset propagation
through the chip, clock alignment, and test points. The PLL controller monitors the PLL status and provides an
output signal indicating when the PLL is locked.
Main PLL power is supplied externally via the Main PLL power-supply pin (AVDDA1). An external EMI filter
circuit must be added to all PLL supplies. See the Hardware Design Guide for KeyStone Devices in ‘‘Related
Documentation from Texas Instruments’’ on page 66 for detailed recommendations. For the best performance, TI
recommends that all the PLL external components be on a single side of the board without jumpers, switches, or
components other than those shown. For reduced PLL jitter, maximize the spacing between switching signal traces
and the PLL external components (C1, C2, and the EMI Filter).
The minimum SYSCLK rise and fall times should also be observed. For the input clock timing requirements, see
Section 7.5.5 ‘‘Main PLL Controller/SRIO/HyperLink/PCIe Clock Input Electrical Data/Timing’’.
CAUTION—The PLL controller module as described in the see the Phase Locked Loop (PLL) Controller for
KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66 includes a
superset of features, some of which are not supported on the TMS320TCI6608 device. The following
sections describe the registers that are supported; it should be assumed that any registers not included in
these sections is not supported by the device. Furthermore, only the bits within the registers described here
are supported. Avoid writing to any reserved memory location or changing the value of reserved bits.
7.5.1 Main PLL Controller Device-Specific Information
7.5.1.1 Internal Clocks and Maximum Operating Frequencies
The Main PLL, used to drive the CorePacs, the switch fabric, and a majority of the peripheral clocks (all but the
DDR3 and the network coprocessor (PASS)) requires a PLL controller to manage the various clock divisions, gating,
and synchronization. The Main PLL’s PLL controller has several SYSCLK outputs that are listed below, along with
the clock description. Each SYSCLK has a corresponding divider that divides down the output clock of the PLL. Note
that dividers are not programmable unless explicitly mentioned in the description below.
• SYSCLK1: Full-rate clock for the CorePacs.
• SYSCLK2: 1/x-rate clock for CorePac (emulation). Default rate for this will be 1/3. This is programmable from
/1 to /32, where this clock does not violate the max of 350 MHz. The SYSCLK2 can be turned off by software.
• SYSCLK3: 1/2-rate clock used to clock the MSMC, HyperLink, CPU/2 SCR, DDR EMIF and CPU/2 EDMA.
• SYSCLK4: 1/3-rate clock for the switch fabrics and fast peripherals. The Debug_SS and ETBs will use this as
well.
• SYSCLK5: 1/y-rate clock for system trace module only. Default rate for this will be 1/5. It is configurable and
the max configurable clock is 210 MHz and min configuration clock is 32 MHz. The SYSCLK5 can be turned
off by software.H
• SYSCLK6: 1/64-rate clock. 1/64 rate clock (emif_ptv) used to clock the PVT compensated buffers for DDR3
EMIF.

•
•
•
•
•
SYSCLK7: 1/6-rate clock for slow peripherals and sources the SYSCLKOUT output pin.
SYSCLK8: 1/z-rate clock. This clock is used as slow_sysclk in the system. Default for this will be 1/64. This is
programmable from /24 to /80.
SYSCLK9: 1/12-rate clock for SmartReflex.
SYSCLK10: 1/3-rate clock for SRIO only.
SYSCLK11: 1/6-rate clock for PSC only.
Only SYSCLK2, SYSCLK5 and SYSCLK8 are programmable on theTMS320TCI6608 device.
Note—In case any of the other programmable SYSCLKs are set slower than 1/64 rate, then SYSCLK8
(SLOW_SYSCLK) needs to be programmed to either match, or be slower than, the slowest SYSCLK in the
system.
7.5.1.2 Main PLL Controller Operating Modes
The Main PLL controller has two modes of operation: bypass mode and PLL mode. The mode of operation is
determined by BYPASS bit of the PLL Secondary control register (SECCTL). In PLL mode, SYSCLK1 is generated
from the PLL output using the values set in PLLM and PLLD bit fields in the MAINPLLCTL0 register. In bypass
mode, PLL input is fed directly out as SYSCLK1.
All hosts must hold off accesses to the DSP while the frequency of its internal clocks is changing. A mechanism must
be in place such that the DSP notifies the host when the PLL configuration has completed.
7.5.1.3 Main PLL Stabilization, Lock, and Reset Times
The PLL stabilization time is the amount of time that must be allotted for the internal PLL regulators to become
stable after device powerup. The PLL should not be operated until this stabilization time has elapsed.
The PLL reset time is the amount of wait time needed when resetting the PLL (writing PLLRST = 1), in order for the
PLL to properly reset, before bringing the PLL out of reset (writing PLLRST = 0). For the Main PLL reset time value,
see Table 7-13.
The PLL lock time is the amount of time needed from when the PLL is taken out of reset (PLLRST = 1) to when to
when the PLL controller can be switched to PLL mode. The Main PLL lock time is given in Table 7-13.

7.5.2.4 PLLDIV Divider Ratio Change Status Register (DCHANGE)
Whenever a different ratio is written to the PLLDIVn registers, the PLLCTL flags the change in the DCHANGE
status register. During the GO operation, the PLL controller will change only the divide ratio of the SYSCLKs with
the bit set in DCHANGE. Note that the ALNCTL register determines if that clock also needs to be aligned to other
clocks. The PLLDIV divider ratio change status register is shown in Figure 7-11 and described in Table 7-18.

7.5.2.9 Reset Isolation Register (RSISO)
This register is used to select the module clocks that must maintain their clocking without pausing through non
power-on reset. Setting any of these bits effectively blocks reset to all PLLCTL registers in order to maintain current
values of PLL multiplier, divide ratios and other settings. Along with setting module specific bit in RSISO, the
corresponding MDCTLx[12] bit also needs to be set in PSC to reset isolate a particular module. For more
information on MDCTLx register see the Power Sleep Controller (PSC) for KeyStone Devices User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 66. The Reset Isolation Register (RSTCTRL) is shown in
Figure 7-16 and described in Table 7-23.

7.5.3 Main PLL Control Register
The Main PLL uses two chip-level registers (MAINPLLCTL0 and MAINPLLCTL1) along with the PLL controller
for its configuration. These MMRs exist inside the Bootcfg space. To write to these registers, software should go
through an un-locking sequence using KICK0/KICK1 registers. For valid configurable values into the
MAINPLLCTL0 and MAINPLLCTL1 registers see Section 2.5.3 ‘‘PLL Boot Configuration Settings’’ on page 34. See
section 3.3.4 ‘‘Kicker Mechanism (KICK0 and KICK1) Register’’ on page 74 for the address location of the registers
and locking and unlocking sequences for accessing the registers. The registers are reset on POR only.

End of Table 7-25
Note—PLLM[5:0] bits of the multiplier is controlled by the PLLM register inside the PLL controller
and PLLM[12:6] bits are controlled by the MAINPLLCTL0 chip-level register. The MAINPLLCTL0 register
PLLM[12:6] bits should be written just before writing to the PLLM register PLLM[5:0] bits in the controller
to have the complete 13 bit value latched when the GO operation is initiated in the PLL controller. See the
Phase Locked Loop (PLL) Controller for KeyStone Devices User Guide in ‘‘Related Documentation from
Texas Instruments’’ on page 66 for the recommended programming sequence. Output Divide ratio and
Bypass enable/disable of the Main PLL is controlled by the SECCTL register in the PLL Controller. See the
7.5.2.1 ‘‘PLL Secondary Control Register (SECCTL)’’ for more details.

7.6 DD3 PLL
The DDR3 PLL generates interface clocks for the DDR3 memory controller. When coming out of power-on reset,
DDR3 PLL is programmed to a valid frequency during the boot config before being enabled and used.
DDR3 PLL power is supplied externally via the Main PLL power-supply pin (AVDDA2). An external EMI filter
circuit must be added to all PLL supplies. See the Hardware Design Guide for KeyStone Devices in ‘‘Related
Documentation from Texas Instruments’’ on page 66. For the best performance, TI recommends that all the PLL
external components be on a single side of the board without jumpers, switches, or components other than those
shown. For reduced PLL jitter, maximize the spacing between switching signal traces and the PLL external
components (C1, C2, and the EMI Filter).

The DDR3 PLL, which is used to drive the DDR PHY for the EMIF, does not use a PLL controller. DDR3 PLL can
be controlled using the DDR3PLLCTL0 and DDR3PLLCTL1 registers located in the Bootcfg module. These MMRs
(memory-mapped registers) exist inside the Bootcfg space. To write to these registers, software should go through
an un-locking sequence using KICK0/KICK1 registers. For suggested configurable values see 2.5.3 ‘‘PLL Boot
Configuration Settings’’ on page 34. See section 3.3.4 ‘‘Kicker Mechanism (KICK0 and KICK1) Register’’ on
page 74 for the address location of the registers and locking and unlocking sequences for accessing the registers. This
register is reset on POR only

7.6.2 DDR3 PLL Device-Specific Information
As shown in Figure 7-21, the output of DDR3 PLL (PLLOUT) is divided by 2 and directly fed to the DDR3 memory
controller. The DDR3 PLL is affected by power-on reset. During power-on resets, the internal clocks of the DDR3
PLL are affected as described in Section 7.4 ‘‘Reset Controller’’ on page 124. DDR3 PLL is unlocked only during the
power-up sequence and is locked by the time the RESETSTAT pin goes high. It does not lose lock during any of the
other resets.
7.6.3 DDR3 PLL Initialization Sequence
The Main PLL and PLL Controller must always be initialized prior to the DDR3 PLL. The sequence shown below
must be followed to initialize the DDR3 PLL.
1. In DDR3PLLCTL1, write ENSAT = 1 (for optimal PLL operation)
2. In DDR3PLLCTL0, write BYPASS = 1 (set the PLL in Bypass)
3. In DDR3PLLCTL1, write PLLRST = 1 (PLL is reset)
4. Program PLLM and PLLD in DDR3PLLCTL0 register
5. Program BWADJ[7:0] in DDR3PLLCTL0 and BWADJ[11:8] in DDR3PLLCTL1 register. BWADJ value must
be set to ((PLLM + 1) >> 1) - 1)
6. Wait for at least 5 us based on the reference clock (PLL reset time)
7. In DDR3PLLCTL1, write PLLRST = 0 (PLL reset is released)
8. Wait for at least 500 *REFCLK cycles * (PLLD + 1) (PLL lock time)
9. In DDR3PLLCTL0, write BYPASS = 0 (switch to PLL mode)
CAUTION—Software must always perform read-modify-write to any registers in the PLL. This is to ensure
that only the relevant bits in the register are modified and the rest of the bits including the reserved bits are
not affected.

7.7 PASS PLL
The PASS PLL generates interface clocks for the Network Coprocessor. Using the PACLKSEL pin the user can select
the input source of PASS PLL as either the output of CORECLK clock reference sources or the PASSCLK clock
reference sources. When coming out of power-on reset, PASS PLL comes out in a bypass mode and needs to be
programmed to a valid frequency before being enabled and used.
PASS PLL power is supplied externally via the Main PLL power-supply pin (AVDDA3). An external EMI filter
circuit must be added to all PLL supplies. Please see the Hardware Design Guide for KeyStone Devices in ‘‘Related
Documentation from Texas Instruments’’ on page 66. for detailed recommendations. For the best performance, TI
recommends that all the PLL external components be on a single side of the board without jumpers, switches, or

7.8 Enhanced Direct Memory Access (EDMA3) Controller
The primary purpose of the EDMA3 is to service user-programmed data transfers between two memory-mapped
slave endpoints on the device. The EDMA3 services software-driven paging transfers (e.g., data movement between
external memory and internal memory), performs sorting or subframe extraction of various data structures, services
event driven peripherals, and offloads data transfers from the device CPU.
There are 3 EDMA Channel Controllers on the TCI6608 DSP, EDMA3CC0, EDMA3CC1, and EDMA3CC2.
• EDMA3CC0 has two transfer controllers: EDMA3TC1 and EDMA3TC2.
• EDMA3CC1 has four transfer controllers: EDMA3TC0, EDMA3TC1, EDMA3TC2, and EDMA3TC3.
• EDMA3CC2 has four transfer controllers: EDMA3TC0, EDMA3TC1, EDMA3TC2, and EDMA3TC3.

In the context of this document, EDMA3TCx associated with EDMA3CCy, and is referred to as EDMA3CCy TCx.
Each of the transfer controllers has a direct connection to the switch fabric. Section 4.2 ‘‘Switch Fabric Connections’’
lists the peripherals that can be accessed by the transfer controllers.
EDMA3CC0 is optimized to be used for transfers to/from/within the MSMC and DDR-3 Subsytems. The others are
to be used for the remaining traffic.
Each EDMA3 Channel Controller includes the following features:
• Fully orthogonal transfer description
– 3 transfer dimensions:
› Array (multiple bytes)
› Frame (multiple arrays)
› Block (multiple frames)
– Single event can trigger transfer of array, frame, or entire block
– Independent indexes on source and destination
• Flexible transfer definition:
– Increment or FIFO transfer addressing modes
– Linking mechanism allows for ping-pong buffering, circular buffering, and repetitive/continuous
transfers, all with no CPU intervention
– Chaining allows multiple transfers to execute with one event
• 128 PaRAM entries for EDMA3CC0, 512 each for EDMA3CC1 and EDMA3CC2
– Used to define transfer context for channels
– Each PaRAM entry can be used as a DMA entry, QDMA entry, or link entry
• 16 DMA channels for EDMA3CC0, 64 each for EDMA3CC1 and EDMA3CC2
– Manually triggered (CPU writes to channel controller register), external event triggered, and chain
triggered (completion of one transfer triggers another)
• 8 Quick DMA (QDMA) channels per EDMA 3 Channel Controller
– Used for software-driven transfers
– Triggered upon writing to a single PaRAM set entry
• 2 transfer controllers and 2 event queues with programmable system-level priority for EDMA3CC0, 4 transfer
controllers and 4 event queues with programmable system-level priority per channel controller for
EDMA3CC1 and EDMA3CC2
• Interrupt generation for transfer completion and error conditions
• Debug visibility
– Queue watermarking/threshold allows detection of maximum usage of event queues
– Error and status recording to facilitate debug
7.8.1 EDMA3 Device-Specific Information
The EDMA supports two addressing modes: constant addressing and increment addressing mode. Constant
addressing mode is applicable to a very limited set of use cases; for most applications increment mode must be used.
On the TCI6608 DSP, the EDMA can use constant addressing mode only with the Enhanced Viterbi-Decoder
Coprocessor (VCP) and the Enhanced Turbo Decoder Coprocessor (TCP). Constant addressing mode is not
supported by any other peripheral or internal memory in the DSP. Note that increment mode is supported by all
peripherals, including VCP and TCP. For more information on these two addressing modes, see the Enhanced Direct
Memory Access 3 (EDMA3) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’
on page 66.

7.8.3 EDMA3 Transfer Controller Configuration
Each transfer controller on a device is designed differently based on considerations like performance requirements,
system topology (like main TeraNet bus width, external memory bus width), etc. The parameters that determine the
transfer controller configurations are:
• FIFOSIZE: Determines the size in bytes for the Data FIFO that is the temporary buffer for the in-flight data.
The data FIFO is where the read return data read by the TC read controller from the source endpoint is stored
and subsequently written out to the destination endpoint by the TC write controller.
• BUSWIDTH: The width of the read and write data buses in bytes, for the TC read and write controller,
respectively. This is typically equal to the bus width of the main TeraNet interface.
• Default Burst Size (DBS): The DBS is the maximum number of bytes per read/write command issued by a
transfer controller.
• DSTREGDEPTH: This determines the number of Destination FIFO register set. The number of Destination
FIFO register set for a transfer controller determines the maximum number of outstanding transfer requests.
All four parameters listed above are fixed by the design of the device.
Table 7-34 provides the configuration for each of the EDMA3 transfer controllers present on the device.

7.8.4 EDMA3 Channel Synchronization Events
The EDMA3 supports up to 16 DMA channels for EDMA3CC0, 64 each for EDMA3CC1 and EDMA3CC2 that can
be used to service system peripherals and to move data between system memories. DMA channels can be triggered
by synchronization events generated by system peripherals. The following tables lists the source of the
synchronization event associated with each of the EDMA EDMA3CC DMA channels. On the TCI6608, the
association of each synchronization event and DMA channel is fixed and cannot be reprogrammed.
For more detailed information on the EDMA3 module and how EDMA3 events are enabled, captured, processed,
prioritized, linked, chained, and cleared, etc., see the Enhanced Direct Memory Access 3 (EDMA3) for KeyStone
Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.9 Interrupts
7.9.1 Interrupt Sources and Interrupt Controller
The CPU interrupts on the TCI6608 device are configured through the C66x CorePac Interrupt Controller. The
interrupt controller allows for up to 128 system events to be programmed to any of the twelve CPU interrupt inputs
(CPUINT4 - CPUINT15), the CPU exception input (EXCEP), or the advanced emulation logic. The 128 system
events consist of both internally-generated events (within the CorePac) and chip-level events.
Additional system events are routed to each of the C66x CorePacs to provide chip-level events that are not required
as CPU interrupts/exceptions to be routed to the interrupt controller as emulation events. Additionally, error-class
events or infrequently used events are also routed through the system event router to offload the C66x CorePac
interrupt selector. This is accomplished through chip interrupt controller (CIC) blocks. This is clocked using CPU/6.

TMS320TCI6608
Multicore Fixed and Floating-Point Digital Signal Processor
SPRS623C—February 2012

The event controllers consist of simple combination logic to provide additional events to each C66x CorePac, plus
the EDMA3CC, CIC0, and CIC1 provide 17 additional events as well as 8 broadcast events to each of the C66x
CorePacs, CIC2 provides 26 and 24 additional events to EDMA3CC1 and EDMA3CC2 respectively, and CIC3
provides 8 and 32 additional events to EDMA3CC0 and HyperLink respectively.
There are a large amount of events on the chip level. The chip level CIC provides a flexible way to combine and
remap those events. Multiple events can be combined to a single event through chip level CIC. However, an event
can only be mapped to a single event output from the chip level CIC. The chip level CIC also allows the software to
trigger system event through memory writes. The broadcast events to C66x CorePacs can be used for
synchronization among multiple cores or inter-processor communication purpose and etc. For more details on the
CIC features, please refer to the Chip Interrupt Controller (CIC) for KeyStone Devices User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 66.
Note—Modules such as MPU, Tracer, and BOOT_CFG have level interrupts and EOI handshaking
interface. The EOI value is 0 for MPU, Tracer, and BOOT_CFG.

7.9.4 NMI and LRESET
Non-maskable interrupts (NMI) can be generated by chip-level registers and the LRESET can be generated by
software writing into LPSC registers. LRESET and NMI can also be asserted by device pins or watchdog timers. One
NMI pin and one LRESET pin are shared by all CorePacs on the device. The CORESEL[3:0] pins can be configured
to select between the CorePacs available as shown in Table 7-47.

7.10 Memory Protection Unit (MPU)
The TCI6608 supports four MPUs:
• One MPU is used to protect main CORE/3 CFG SCR (CFG space of all slave devices on the SCR is protected
by the MPU).
• Two MPUs are used for QM_SS (one for DATA PORT port and another is for CFG PORT port).
• One MPU is used for Semaphore.
This section contains MPU register map and details of device-specific MPU registers only. For MPU features and
details of generic MPU registers, see the Memory Protection Unit (MPU) for KeyStone Devices User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 66.
The following tables show the configuration of each MPU and the memory regions protected by each MPU.

Table 7-51 shows the privilege ID of each CORE and every mastering peripheral. Table 7-51 also shows the privilege
level (supervisor vs. user), security level (secure vs. non-secure), and access type (instruction read vs. data/DMA read
or write) of each master on the device. In some cases, a particular setting depends on software being executed at the
time of the access or the configuration of the master peripheral.

1 Some of the PKTDMA-based peripherals require multiple master IDs. QMS_PKTDMA is assigned with 88,89,90,91, but only 88-89 are actually used. For Network coprocessor
packet DMA port, 56,57,58,59 are assigned while only 1 (56) is actually used. There are two master ID values are assigned for the QM_second master port, one master ID
for external linking RAM and the other one for the PDSP/MCDM accesses.
2 The master ID for MSMC is for the transactions initiated by MSMC internally and sent to the DDR.
3 All CP_traces are set to the same master ID and bit 7 of the master ID needs to be 1.

7.10.2 MPU Programmable Range Registers
7.10.2.1 Programmable Range n Start Address Register (PROGn_MPSAR)
The programmable address start register holds the start address for the range. This register is writeable by a
supervisor entity only. If NS = 0 (non-secure mode) in the associated MPPA register, then the register is also
writeable only by a secure entity.
The start address must be aligned on a page boundary. The size of the page is 1K byte. The size of the page determines
the width of the address field in MPSAR and MPEAR.

7.10.2.2 Programmable Range n End Address Register (PROGn_MPEAR)
The programmable address end register holds the end address for the range. This register is writeable by a supervisor
entity only. If NS = 0 (non-secure mode) in the associated MPPA register then the register is also only writeable by
a secure entity.
The end address must be aligned on a page boundary. The size of the page depends on the MPU number. The page
size for MPU1 is 1K byte and for MPU2 it is 64K bytes. The size of the page determines the width of the address field
in MPSAR and MPEAR

7.11 DDR3 Memory Controller
The 64-bit DDR3 Memory Controller bus of the TMS320TCI6608 is used to interface to JEDEC standard-compliant
DDR3 SDRAM devices. The DDR3 external bus interfaces only to DDR3 SDRAM devices; it does not share the bus
with any other types of peripherals.
7.11.1 DDR3 Memory Controller Device-Specific Information
The TMS320TCI6608 includes one 64-bit wide 1.5-V DDR3 SDRAM EMIF interface. The DDR3 interface can
operate at 800 Mega Transfers per Second (MTS), 1033 MTS, 1333 MTS, and 1600 MTS.
Due to the complicated nature of the interface, a limited number of topologies will be supported to provide a 16-bit,
32-bit, or 64-bit interface.
The DDR3 electrical requirements are fully specified in the DDR Jedec Specification JESD79-3C. Standard DDR3
SDRAMs are available in 8- and 16-bit versions, allowing for the following bank topologies to be supported by the
interface:
• 72-bit: Five 16-bit SDRAMs (including 8 bits of ECC)
• 72-bit: Nine 8-bit SDRAMs (including 8 bits of ECC)
• 36-bit: Three 16-bit SDRAMs (including 4 bits of ECC)
• 36-bit: Five 8-bit SDRAMs (including 4 bits of ECC)
• 64-bit: Four 16-bit SDRAMs
• 64-bit: Eight 8-bit SDRAMs
• 32-bit: Two 16-bit SDRAMs
• 32-bit: Four 8-bit SDRAMs
• 16-bit: One 16-bit SDRAM
• 16-bit: Two 8-bit SDRAM
The approach to specifying interface timing for the DDR3 memory bus is different than on other interfaces such as
I2C or SPI. For these other interfaces, the device timing was specified in terms of data manual specifications and I/O
buffer information specification (IBIS) models. For the DDR3 memory bus, the approach is to specify compatible
DDR3 devices and provide the printed circuit board (PCB) solution and guidelines directly to the user.
A race condition may exist when certain masters write data to the DDR3 memory controller. For example, if
master A passes a software message via a buffer in external memory and does not wait for an indication that the write
completes, before signaling to master B that the message is ready, when master B attempts to read the software
message, then the master B read may bypass the master A write and, thus, master B may read stale data and,
therefore, receive an incorrect message.
Some master peripherals (e.g., EDMA3 transfer controllers with TCCMOD=0) will always wait for the write to
complete before signaling an interrupt to the system, thus avoiding this race condition. For masters that do not have
a hardware specification of write-read ordering, it may be necessary to specify data ordering via software.
If master A does not wait for indication that a write is complete, it must perform the following workaround:
1. Perform the required write to DDR3 memory space.
2. Perform a dummy write to the DDR3 memory controller module ID and revision register.
3. Perform a dummy read to the DDR3 memory controller module ID and revision register.
4. Indicate to master B that the data is ready to be read after completion of the read in step 3. The completion of
the read in step 3 ensures that the previous write was done.

7.11.2 DDR3 Memory Controller Electrical Data/Timing
The KeyStone DSP DDR3 Implementation Guidelines in ‘‘Related Documentation from Texas Instruments’’ on
page 66 specifies a complete DDR3 interface solution as well as a list of compatible DDR3 devices. The DDR3
electrical requirements are fully specified in the DDR3 Jedec Specification JESD79-3C. TI has performed the
simulation and system characterization to ensure all DDR3 interface timings in this solution are met; therefore, no
electrical data/timing information is supplied here for this interface.
Note—TI supports only designs that follow the board design guidelines outlined in the application report.
7.12 I2C Peripheral
The inter-integrated circuit (I2C) module provides an interface between DSP and other devices compliant with
2
2
Philips Semiconductors Inter-IC bus (I C bus) specification version 2.1 and connected by way of an I C bus.
External components attached to this 2-wire serial bus can transmit/receive up to 8-bit data to/from the DSP
through the I2C module.
2
7.12.1 I C Device-Specific Information
2
The TMS320TCI6608 device includes an I C peripheral module.
2
Note—When using the I
C module, ensure there are external pullup resistors on the SDA and SCL pins.
2
The I C modules on the TCI6608 may be used by the DSP to control local peripheral ICs (DACs, ADCs, etc.) or may
be used to communicate with other controllers in a system or to implement a user interface.
2
2
The I C port is compatible with Philips I C specification revision 2.1 (January 2000) and supports:
• Fast mode up to 400 Kbps (no fail-safe I/O buffers)
• Noise filter to remove noise 50 ns or less
• 7-bit and 10-bit device addressing modes
• Multi-master (transmit/receive) and slave (transmit/receive) functionality
• Events: DMA, interrupt, or polling
• Slew-rate limited open-drain output buffers

2 A Fast-mode I C-bus™ device can be used in a Standard-mode I C-bus™ system, but the requirement tsu(SDA-SCLH) ≥ 250 ns must then be met. This will automatically be the
case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the
SDA line tr max + tsu(SDA-SCLH) = 1000 + 250 = 1250 ns (according to the Standard-mode I2C-Bus Specification) before the SCL line is released.
3 A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the undefined region of the falling edge
of SCL.
4 The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal.
5 Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall-times are allowed.

7.13 SPI Peripheral
The serial peripheral interconnect (SPI) module provides an interface between the DSP and other SPI-compliant
devices. The primary intent of this interface is to allow for connection to a SPI ROM for boot. The SPI module on
TCI6608 is supported only in Master mode. Additional chip-level components can also be included, such as
temperature sensors or an I/O expander.

7.14 HyperLink Peripheral
The TMS320TCI6608 includes the HyperLink bus for companion chip/die interfaces. This is a four-lane SerDes
interface designed to operate at up to 12.5 Gbaud per lane. The supported data rates include 1.25 Gbaud,
3.125 Gbaud, 6.25 Gbaud, 10 Gbaud and 12.5 Gbaud. The interface is used to connect with external accelerators.
The HyperLink links must be connected with DC coupling.
The interface includes the Serial Station Management Interfaces used to send power management and flow messages
between devices. This consists of four LVCMOS inputs and four LVCMOS outputs configured as two 2-wire output
buses and two 2-wire input buses. Each 2-wire bus includes a data signal and a clock signal.
7.14.1 HyperLink Device-Specific Interrupt Event
The HyperLink has 64 input events. Events 0 to 31come from the chip level interrupt controller and events 32 to 63
are from queue-pending signals from the Queue Manager to monitor some of the transmission queue status.

7.15 UART Peripheral
The universal asynchronous receiver/transmitter (UART) module provides an interface between the DSP and
UART terminal interface or other UART-based peripheral. The UART is based on the industry standard TL16C550
asynchronous communications element, which in turn is a functional upgrade of the TL16C450. Functionally
similar to the TL16C450 on power up (single character or TL16C450 mode), the UART can be placed in an alternate
FIFO (TL16C550) mode. This relieves the DSP of excessive software overhead by buffering received and transmitted
characters. The receiver and transmitter FIFOs store up to 16 bytes including three additional bits of error status per
byte for the receiver FIFO.
The UART performs serial-to-parallel conversions on data received from a peripheral device and parallel-to-serial
conversion on data received from the DSP. The DSP can read the UART status at any time. The UART includes
control capability and a processor interrupt system that can be tailored to minimize software management of the
communications link. For more information on UART, see the Universal Asynchronous Receiver/Transmitter
(UART) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.16 PCIe Peripheral
The two-lane PCI express (PCIe) module on the device provides an interface between the DSP and other
PCIe-compliant devices. The PCI Express module provides low-pin-count, high-reliability, and high-speed data
transfer at rates of 5.0 GBaud per lane on the serial links. For more information, see the Peripheral Component
Interconnect Express (PCIe) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’
on page 66. The PCIe electrical requirements are fully specified in the PCI Express Base Specification Revision 2.0
of PCI-SIG. TI has performed the simulation and system characterization to ensure all PCIe interface timings in this
solution are met; therefore, no electrical data/timing information is supplied here for this interface.

7.19 Packet Accelerator
The packet accelerator provides L2 to L4 classification functionalities. It supports classification for Ethernet, VLAN,
MPLS over Ethernet, IPv4/6, GRE over IP, and other session identification over IP such as TCP and UDP ports. It
maintains 8K multiple-in, multiple-out hardware queues. It also provides checksum capability as well as some QoS
capabilities. It enables a single IP address to be used for a multi-core device. It can process up to 1.5 M pps. The
packet accelerator is coupled with the network coprocessor. For more information, see the Packet Accelerator (PA)
for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.
7.20 Security Accelerator
The security accelerator provides wire-speed processing on 1-Gbps Ethernet traffic on IPSec, SRTP, and 3GPP Air
interface security protocols. It functions on the packet level with the packet and the associated security context being
one of these above three types. The security accelerator is coupled with network coprocessor, and receives the packet
descriptor containing the security context in the buffer descriptor, and the data to be encrypted/decrypted in the
linked buffer descriptor. For more information, see the Security Accelerator (SA) for KeyStone Devices User Guide in
‘‘Related Documentation from Texas Instruments’’ on page 66.

7.21 Gigabit Ethernet (GbE) Switch Subsystem
The Gigabit Ethernet (GbE) switch subsystem provide an efficient interface between the TMS320TCI6608 DSP and
the networked community. The GbE switch subsystem supports 10Base-T (10 Mbits/second [Mbps]), and
100BaseTX (100 Mbps), in half- or full-duplex mode, and 1000BaseT (1000 Mbps) in full-duplex mode, with
hardware flow control and quality-of-service (QOS) support. The GbE switch subsystem is coupled with network
coprocessor. For more information, see the Gigabit Ethernet (GbE) Switch Subsystem for KeyStone Devices User
Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.
Each device has a unique MAC address. There are two registers to hold these values, MACID1 (0x02620110) and

7.22 Management Data Input/Output (MDIO)
The management data input/output (MDIO) module implements the 802.3 serial management interface to
interrogate and controls up to 32 Ethernet PHY(s) connected to the device, using a shared two-wire bus. Application
software uses the MDIO module to configure the auto-negotiation parameters of each PHY attached to the GbE
switch subsystem, retrieve the negotiation results, and configure required parameters in the GbE switch subsystem
module for correct operation. The module is designed to allow almost transparent operation of the MDIO interface,
with very little maintenance from the core processor. For more information, see the Gigabit Ethernet (GbE) Switch
Subsystem for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.23 Timers
The timers can be used to: time events, count events, generate pulses, interrupt the CPU and send synchronization
events to the EDMA3 channel controller.
7.23.1 Timers Device-Specific Information
The TMS320TCI6608 device has sixteen 64-bit timers in total. Timer0 through Timer7 are dedicated to each of the
eight CorePacs as a watchdog timer and can also be used as general-purpose timers. Each of the other eight timers
can also be configured as a general-purpose timer only, with each timer programmed as a 64-bit timer or as two
separate 32-bit timers.
When operating in 64-bit mode, the timer counts either VBUS clock cycles or input (TINPLx) pulses (rising edge)
and generates an output pulse/waveform (TOUTLx) plus an internal event (TINTLx) on a software-programmable
period.
When operating in 32-bit mode, the timer is split into two independent 32-bit timers. Each timer is made up of two
32-bit counters: a high counter and a low counter. The timer pins, TINPLx and TOUTLx are connected to the low
counter. The timer pins, TINPHx and TOUTHx are connected to the high counter.
When operating in watchdog mode, the timer counts down to 0 and generates an event. It is a requirement
that software writes to the timer before the count expires, after which the count begins again. If the count ever
reaches 0, the timer event output is asserted. Reset initiated by a watchdog timer can be set by programming ‘‘Reset
Type Status Register (RSTYPE)’’ on page 138 and the type of reset initiated can set by programming ‘‘Reset
Configuration Register (RSTCFG)’’ on page 139. For more information, see the 64-bit Timer (Timer 64) for KeyStone
Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.24 Serial RapidIO (SRIO) Port
The SRIO port on the TMS320TCI6608 device is a high-performance, low pin-count interconnect aimed for
embedded markets. The use of the RapidIO interconnect in a baseband board design can create a homogeneous
interconnect environment, providing even more connectivity and control among the components. RapidIO is based
on the memory and device addressing concepts of processor buses where the transaction processing is managed
completely by hardware. This enables the RapidIO interconnect to lower the system cost by providing lower latency,
reduced overhead of packet data processing, and higher system bandwidth, all of which are key for wireless
interfaces. For more information, see the Serial RapidIO (SRIO) for KeyStone Devices User Guide in ‘‘Related
Documentation from Texas Instruments’’ on page 66.

7.26 Semaphore2
The device contains an enhanced Semaphore module for the management of shared resources of the DSP C66x
CorePacs. The Semaphore enforces atomic accesses to shared chip-level resources so that the read-modify-write
sequence is not broken. The semaphore block has unique interrupts to each of the cores to identify when that core
has acquired the resource.
Semaphore resources within the module are not tied to specific hardware resources. It is a software requirement to
allocate semaphore resources to the hardware resource(s) to be arbitrated.
The Semaphore module supports 8 masters and contains 32 semaphores to be used within the system.
There are two methods of accessing a semaphore resource:
• Direct Access: A core directly accesses a semaphore resource. If free, the semaphore will be granted. If not, the
semaphore is not granted.
• Indirect Access: A core indirectly accesses a semaphore resource by writing it. Once it is free, an interrupt
notifies the CPU that it is available.
7.27 Emulation Features and Capability
7.27.1 Advanced Event Triggering (AET)
The TMS320TCI6608 device supports Advanced Event Triggering (AET). This capability can be used to debug
complex problems as well as understand performance characteristics of user applications. AET provides the
following capabilities:
• Hardware Program Breakpoints: specify addresses or address ranges that can generate events such as halting
the processor or triggering the trace capture.
• Data Watchpoints: specify data variable addresses, address ranges, or data values that can generate events
such as halting the processor or triggering the trace capture.
• Counters: count the occurrence of an event or cycles for performance monitoring.
• State Sequencing: allows combinations of hardware program breakpoints and data watchpoints to precisely
generate events for complex sequences.
For more information on AET, see the following documents in ‘‘Related Documentation from Texas Instruments’’
on page 66:
• Using Advanced Event Triggering to Find and Fix Intermittent Real-Time Bugs application report
• Using Advanced Event Triggering to Debug Real-Time Problems in High Speed Embedded Microprocessor
Systems application report
7.27.2 Trace
The TCI6608 device supports Trace. Trace is a debug technology that provides a detailed, historical account of
application code execution, timing, and data accesses. Trace collects, compresses, and exports debug information
for analysis. Trace works in real-time and does not impact the execution of the system.
For more information on board design guidelines for Trace Advanced Emulation, see the 60-Pin Emulation Header
Technical Reference in ‘‘Related Documentation from Texas Instruments’’ on page 66.

7.27.3 IEEE 1149.1 JTAG
The JTAG interface is used to support boundary scan and emulation of the device. The boundary scan supported
allows for an asynchronous TRST and only the 5 baseline JTAG signals (e.g., no EMU[1:0]) required for boundary
scan. Most interfaces on the device follow the Boundary Scan Test Specification (IEEE1149.1), while all of the SerDes
(SRIO and SGMII) support the AC-coupled net test defined in AC-Coupled Net Test Specification (IEEE1149.6).
It is expected that all compliant devices are connected through the same JTAG interface, in daisy-chain fashion, in
accordance with the specification. The JTAG interface uses 1.8-V LVCMOS buffers, compliant with the Power
Supply Voltage and Interface Standard for Nonterminated Digital Integrated Circuit Specification (EAI/JESD8-5).
7.27.3.1 IEEE 1149.1 JTAG Compatibility Statement
For maximum reliability, the TCI6608 DSP includes an internal pulldown (IPD) on the TRST pin to ensure that
TRST will always be asserted upon power up and the DSP's internal emulation logic will always be properly
initialized when this pin is not routed out. JTAG controllers from Texas Instruments actively drive TRST high.
However, some third-party JTAG controllers may not drive TRST high but expect the use of an external pullup
resistor on TRST. When using this type of JTAG controller, assert TRST to initialize the DSP after powerup and
externally drive TRST high before attempting any emulation or boundary scan operations.
