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.
ADVANCE INFORMATION
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-Gbps 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 TMS320C6674 DSP is a highest-performance fixed/floating-point DSP that is based on TI's KeyStone multicore
architecture. Integrated with 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 TMS320C6674 DSP offers 5 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 allow for efficient data
management between the various chip components, Teranet switch fabric that is a 2 TB non-blocking switch fabric
enabling fast and contention free internal data movement, as well as the Multicore shared memory controller that
allows access to shared and external memory directly without drawing from switch fabric capacity.
For fixed point use, the C66x core has 4X the multiply accumulate (MAC) capability of current generation 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 targeted for floating point and vector math oriented processing,
compared to the C64x+ core. 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 C6674 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 64 bit DDR-3 running at 1600MHz and has ECC DRAM support.

2.2 DSP Core Description
ADVANCE INFORMATION
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

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.

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
‘‘Reset Controller’’.
The C6674 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 (literature number
SPRUGY5).

2.5 Boot Modes Supported and PLL Settings
ADVANCE INFORMATION
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 CorePac 0 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), the C66x CorePac 0
then begins execution from the provided boot entry point, other C66x CorePac’s are released from reset based
on interrupts generated by C66x CorePac 0, see the Bootloader for the C66x DSP User Guide (literature number
SPRUGY5) for more details.
• Secure ROM Boot - On secure devices, the C66x CorePac 0 is released from reset and begin executing from
secure ROM. Software in the secure ROM will free up internal RAM pages, after which the C66x CorePac 0
initiates the boot process. The C66x CorePac 0 performs any authentication and decryption required on the
bootloaded image prior to beginning execution.
The boot process performed by the C66x CorePac 0 in public ROM boot and secure ROM boot are determined by
the BOOTMODE[12:0] value in the DEVSTAT register. The C66x CorePac 0 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 I2C Boot Device Configuration
2.5.2.5.1 I2C Master Mode
In master mode, the I2C 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.

2.5.3 PLL Boot Configuration Settings
The PLL default settings are determined by the BOOTMODE[12:10] bits. The Table 2-13 shows settings for various
input clock frequencies. This will set the PLL to the maximum clock setting for the device.
CLK = CLKIN × (PLLM+1) ÷ (2 × (PLLD+1))
The PA configuration is also shown. The PA 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 PA SerDes clock). See Table 2-3 for details on
configuring Ethernet boot mode. See section 7.8 ‘‘Main PLL and PLL Controller’’ on page 209 for further details

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 77.
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 (literature number SPRABI2).

2.9 Development
2.9.1 Development Support
In case the customer would like to develop their own features and software on the C6674 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).
ADVANCE INFORMATION
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 TMS320C6674 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. By
default, the peripherals on the device are disabled and need to be enabled by software before being used.
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.
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 77.

1 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 Section 3.4 ‘‘Pullup/Pulldown Resistors’’ on page 77.

3.2 Peripheral Selection After Device Reset
Several of the peripherals on the TMS320C6674 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. Then, 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 (literature
number SPRUGV4).
3.3 Device State Control Registers
The TMS320C6674 device has a set of registers that are used to control the status of its peripherals. These registers
are shown in Table 3-2.

3.3.4 Kicker Mechanism (KICK0 and KICK1) Register
ADVANCE INFORMATION
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 62 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. In order to ensure protection to all Bootcfg MMRs, software must always re-lock the kicker
mechanism after completing the MMR writes.
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

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.

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 (DSP/6) followed
by a deassertion of 4 bootcfg clock cycles. Generating the pulse will result in 8 DSP/6 cycle pulse blocking window.
Write to IPCGRH with IPCG bit (bit 0) set will only generate a pulse if they are beyond 8 DSP/6 cycle period. The

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.
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.

ADVANCE INFORMATION
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.

4 System Interconnect
On the TMS320C6674 device, the C66x CorePac, the EDMA3 transfer controllers, and the system peripherals are
interconnected through two switch fabrics. The switch fabrics allow for low-latency, concurrent data transfers
between master peripherals and slave peripherals. The switch fabrics also allow for seamless arbitration between the
system masters when accessing system slaves.
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 only have one type of interface. Furthermore, 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. However, in some cases, the configuration bus is
also used to transfer data. Similarly, the data bus can also be used to access the register space of a peripheral. For
example, the DDR3 memory controller registers are accessed through their data bus interface.
The C66x CorePac, 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 EDMA3 to perform transfers to and from them. Examples of masters
2
include the EDMA3 traffic controllers, SRIO, and EMAC. Examples of slaves include the SPI, UART, and I C.
The device contains two switch fabrics (the TeraNet) through which masters and slaves communicate. The data
switch fabric, known as the data switched central resource (SCR), is a high-throughput interconnect mainly used to
move data across the system (for more information, see Section 4.2 ‘‘Data Switch Fabric Connections’’). The data
SCR is further divided into two smaller SCRs. One connects very high speed masters to slaves via 256-bit data buses
running at a DSP/2 frequency. The other connects masters to slaves via 128-bit data buses running at a DSP/3
frequency. Peripherals that match the native bus width of the SCR it is connected to can connect directly to the data
SCR; other peripherals require a bridge.
The configuration switch fabric, also known as the configuration switch central resource (SCR), is mainly used to
access peripheral registers (for more information, see Section 4.3 ‘‘Configuration Switch Fabric’’). The
configuration SCR connects the C66x CorePac and masters on the data switch fabric to slaves via
32-bit configuration buses running at a DSP/3 frequency. As with the data SCR, some peripherals require the use of
a bridge to interface to the configuration SCR.
Bridges perform a variety of functions:
• Conversion between configuration bus and data bus.
• Width conversion between peripheral bus width and SCR bus width.
• Frequency conversion between peripheral bus frequency and SCR bus frequency.

4.3 Configuration Switch Fabric
A detailed figure will be added here for a future release. All masters can talk to all slaves on the configuration switch
fabric.
4.4 Bus Priorities
The priority level of all master peripheral traffic is defined at the TeraNet boundary. User programmable priority
registers will be present to allow software configuration of the data traffic through the TeraNet. Note that a lower
number means higher priority - PRI = 000b = urgent, PRI = 111b = low.
ADVANCE INFORMATION
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 4-1 and
Table 4-3.

5.1 Memory Architecture
Each C66x CorePac of the TMS320C6674 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 C6674 has a unique location in the memory map (see Table 2-2 ‘‘Memory Map
Summary for TMS320C6674’’ on page 19.
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.
ADVANCE INFORMATION
The on-chip bootloader changes the reset configuration for L1P and L1D. For more information, see the Bootloader
for the C66x DSP User Guide (literature number SPRUGY5).
For more information on the operation L1 and L2 caches, see the C66x DSP Cache User Guide (literature number
SPRUGY8).

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 MSMC SRAM
The MSMC SRAM configuration for the C6674 device is as follows:
• Memory size is 4096KB
• The MSMC 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 (literature number SPRUGW7).
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.
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
Local Bit

Description
No access to memory page is permitted.
0
1
Only direct access by DSP is permitted.
1
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

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
ADVANCE INFORMATION
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) System peripherals with no fields in PRI_ALLOC have their own
registers to program their priorities, see section 4.4 ‘‘Bus Priorities’’ on page 82 for more details.
More information on the bandwidth management features of the C66x CorePac can be found in the C66x CorePac
User Guide (literature number SPRUGW0.)
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 C6674 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 (literature number SPRUGW0).
5.5 C66x CorePac Resets
Table 5-2 shows the reset types supported on the C6674 device and how they affect the resetting of the CorePac,
either both globally or just locally.

7 TMS320C6674 Peripheral Information and Electrical Specifications
This chapter covers the various peripherals on the TMS320C6674 DSP. Peripheral-specific information, timing
diagrams, electrical specifications, and register memory maps are described in this chapter.
7.1 Parameter Information
The data manual provides timing at the device pin. For output analysis, the transmission line and associated
parasitics (vias, multiple nodes, etc.) must also be taken into account. The transmission line delay varies depending
on the trace length. An approximate range for output delays can vary from 176 ps to 2 ns depending on the end
product design. For recommended transmission line lengths, see the appropriate application notes, user guides, and
design guides. A transmission line delay of 2 ns was used for all output measurements, except the DDR3, which was
evaluated using a 528-ps delay.

7.1.2 Timing Parameters and Board Routing Analysis
ADVANCE INFORMATION
The timing parameter values specified in this data sheet do not include delays by board routings. As a good board
design practice, such delays must always be taken into account. Timing values may be adjusted by
increasing/decreasing such delays. TI recommends using the available I/O buffer information specification (IBIS)
models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate timing analysis
for a given system, see the Using IBIS Models for Timing Analysis application report (literature number TBD). If
needed, external logic hardware such as buffers may be used to compensate any timing differences.
For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device and
from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time margin,
but also tends to improve the input hold time margins (see Table 7-1 and Figure 7-4).

This is followed by the device initialization phase. Either POR or RESETFULL may be used to trigger the end of the
initialization phase, but both must be inactive for the initialization to complete. The differences between
POR-controlled initialization and RESETFULL initialization are described below. The following section has a
mention of REFCLK in many places. REFCLK here refers to the clock input that has been selected as the source for
the Main PLL. See Figure 7-23 for more details.
For more information on Power Supply sequencing see the Hardware Design Guide for KeyStone Devices (literature
number SPRABI2).
7.3.1.1 POR-Controlled Device Initialization
The timing diagrams in the figures below show the power sequencing and reset control of the device when
RESETFULL is held high and POR is used to control the device initialization. In this mode, POR must be held low
until the power has been stable for the required 100 μsec and the device initialization requirements have been met.
On the rising edge of POR, the HHV signal will go inactive allowing the core to control the state of the output buffers
and pulls. The POR must be held for the 100 μsec after the power has stabilized plus the time period between that100
μsec and when the clock is active in addition to the 16 μsec following the active clock. If the clock becomes active
before the 100 μsec stabilization period has expired, only the additional 16 μsecs of POR is required to complete
initialization.
Note—REFCLK must always be active before POR can be removed.

ADVANCE INFORMATION
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.

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.
t2a
• 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 (core constant) should trail CVDD
(core AVS) 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.
t2b
• 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.
t2c
• The DDRCLK and REFCLK may begin to toggle anytime between when CVDD is at a valid level and the setup time before POR goes high
specified by t7.
t3
• DVDD18 (1.8 V) supply is ramped up followed coincidentally by HHV (1.8 V).
• 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.
t4a
• 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.

• RESETFULL and RESET may be driven high anytime after DVDD18 is at a valid level. In a POR controlled boot both RESETFULL and RESET
must be high before POR is driven high.
t5
• POR must continue to remain low for at least 100 μs after power has stabilized.
End Power Stabilization Phase
t6
• Device initialization requires 500 REFCLK 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.
t7
• The rising edge of POR 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.

remain low through Power Stabilization Phase.
• Filtered versions of 1.8V can ramp simultaneously with DVDD18.
• RESETSTAT is driven low once the DVDD18 supply is available.
• All input and bidirectional pins must not be driven or pulled high until DVDD18 is present. Driving an input or bidirectional pin before
DVDD18 could cause damage to the device.

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 (core constant) should trail CVDD
(core AVS) 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.

Begin Device Initialization
• Device initialization requires 500 REFCLK 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.
• POR must remain low.
t7
• The rising edge of the POR 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.

7.3.1.2 RESETFULL-Controlled Device Initialization
The timing diagrams in the figures below show the power sequencing and reset control of the device when
RESETFULL is used to extend device initialization. In this mode, POR may be removed after the power has been
stable for the required 100 μsec, but RESETFULL may be held low until the device initialization requirements have
been met. On the rising edge of POR, the HHV signal will go inactive.
Note—REFCLK must always be active before POR can be removed.

7.3.1.3 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.
7.3.2 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.
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 7-7 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.

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 (literature number SPRABI2).

7.3.4 SmartReflex
Texas Instruments' SmartReflex technology is used to decrease both static and dynamic power consumption while
maintaining the device performance. SmartReflex in the TMS320C6674 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
TMS320C6674 device.
To guarantee maximizing performance and minimizing power consumption of the device, SmartReflex is required
to be implemented whenever the TMS320C6674 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 (literature number SPRABI2).

ADVANCE INFORMATION
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.

7.4 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 C6674 DSP, TPCC0, TPCC1, and TPCC2. TPCC0 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.
ADVANCE INFORMATION
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 TPCC0, 512 each for TPCC1 and TPCC2
– 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 TPCC0, 64 each for TPCC1 and TPCC2
– 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 TPCC0, 4 transfer
controllers and 4 event queues with programmable system-level priority per channel controller for TPCC1 and
TPCC2
• 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
In the context of this document, TPTCs associated with TPCC0 are referred to as TPCC0 TPTC0 and1. TPTCs
associated with TPCC1 and 2 are each referred to as TPCCx TPTC0 - 3, where x is 1 or 2. Each of the transfer
controllers has a direct connection to the switched central resource (SCR). ‘‘DSP/2 Data SCR Connection Matrix’’
on page 80 and ‘‘DSP/3 Data SCR Connection Matrix’’ on page 82 lists the peripherals that can be accessed by the
transfer controllers.

7.4.2 EDMA3 Channel Synchronization Events
The EDMA3 supports up to 16 DMA channels for TPCC0, 64 each for TPCC1 and TPCC2 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 TPCC DMA channels. On the C6674, the association of each
synchronization event and DMA channel is fixed and cannot be reprogrammed.

ADVANCE 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 can be used.
On the C6674 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 (literature number SPRUGS5).

prioritized, linked, chained, and cleared, etc., see the Enhanced Direct Memory Access 3 (EDMA3) for KeyStone

7.5 Interrupts
7.5.1 Interrupt Sources and Interrupt Controller
The CPU interrupts on the C6674 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 INTC blocks, INTC[2:0], with one controller per C66x CorePac.
This is clocked using CPU/6.
The event controllers consist of simple combination logic to provide additional events to each C66x CorePac, plus
the TPCC. INTC0 provides 17 additional events as well as 8 broadcast events to each of the C66x CorePacs, INTC2
provides 26 and 24 additional events to TPCC1 and TPCC2 respectively, and INTC3 provides 8 and 32additional
events to TPCC0 and HyperLink respectively.
There are a large amount of events on the chip level. The chip level INTC provides a flexible way to combine and
remap those events. Multiple events can be combined to a single event through chip level INTC. However, an event
can only be mapped to a single event output from the chip level INTC. The chip level INTC 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
INTC features, please refer to the Interrupt Controller (INTC) for KeyStone Devices User Guide (literature number
SPRUGW4).

7.6 MPU
The C6674 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 (literature
number SPRUGW5).
ADVANCE INFORMATION
The following tables show the configuration of each MPU and the memory regions protected by each MPU.

Table 7-42 shows the privilege ID of each CORE and every mastering peripheral. Table 7-42 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.

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

7.7 Reset Controller
The reset controller detects the different type of resets supported on the TMS320C6674 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
ADVANCE INFORMATION
Table 7-58 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 205

Total reset of the chip. Everything on the device is reset to its default
state in response to this. Activates the POR signal on chip, which is used
to reset test/emu logic. Boot configurations are latched. ROM boot
process is initiated.
Resets everything except for test/emu logic and Reset Isolation
modules. Emulator and Reset Isolation modules stay alive during this
reset. This reset is also different from POR in that the PLLCTL assumes
power and clocks are stable when Device Reset is asserted. Boot
configurations are not latched. ROM boot process is initiated.
Toggles RESETSTAT pin
Software can program these initiators to be hard or soft. Hard reset is
the default, but can be programmed to be Soft reset. Soft Reset will
behave like Hard Reset except that PCIe MMRs,EMIF16 MMRs, DDR3
EMIF MMRs, and External Memory contents are retained. Boot
configurations are not latched. ROM boot process is initiated.
Toggles RESETSTAT pin
MMR bit in LPSC controls C66x CorePac local reset. Used by Watchdog Does not toggle
RESETSTAT pin
Timers (in the event of a timeout) to reset C66x CorePac. Can also be
initiated by LRESET device pin. C66x CorePac memory system and Slave
DMA port are still alive when C66x CorePac is in local reset. Provides a
local reset of the C66x CorePac, without destroying clock alignment or
memory contents. Does not initiate ROM boot process.
End of Table 7-58
7.7.1 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.

Copyright 2010 Texas Instruments Incorporated
TMS320C6674
Multicore Fixed and Floating-Point Digital Signal Processor
SPRS692—November 2010
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 62).
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.
7.7.2 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.

7.7.3 Soft Reset
A soft reset will behave like a hard reset except that the PCIe MMRs and DDR3 EMIF MMRs contents are retained.
POR should also remain de-asserted during this time.
ADVANCE INFORMATION
Soft 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.
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. The following external memory contents are maintained
during a soft reset:
• DDR3 MMRs: 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.
• PCIe MMRs: The contents of the memory connected to the EMIFA are retained. The EMIFA registers are not
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.

7.7.4 Local Reset
Local reset is initiated by the following (for more details see the Phase Locked Loop (PLL) Controller for KeyStone
Devices User Guide (literature number SPRUGV2):
• LRESET pin
• Watchdog Timer should cause one of the below based on Reset Multiplex “ESTMUXn” register setting (See
TBD for details):
– Local Reset
– NMI

7.8 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 (literature number
SPRUGV2).
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 7-23 shows a block diagram of the main PLL controller. The
following paragraphs define the clocks and PLL controller parameters.

The inputs, multiply factor within the PLL, and post-division for each of the chip-level clocks from the PLL output.
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 (literature number
SPRABI2). 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).
ADVANCE INFORMATION
The minimum SYSCLK rise and fall times should also be observed. For the input clock timing requirements, see
Section 7.8.4 ‘‘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 (literature number SPRUGV2) includes a superset of features, some of which
are not supported on the TMS320C6674 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.
7.8.1 Main PLL Controller Device-Specific Information
7.8.1.1 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 PASS modules) 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.
• REFCLK: Full-rate clock for CorePac 0~CorePac 7.
• SYSCLK2: 1/x-rate clock for CorePac (emulation) and the ADTF module. 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 L2/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.
• 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_sysclck 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 TMS320C6674 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.
7.8.1.2 Main PLL Controller Operating Modes
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.
7.8.1.3 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 expired.
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 7-62.
The PLL lock time is the amount of time needed from when the PLL is taken out of reset (PLLRST = 1 with
PLLEN = 0) to when to when the PLL controller can be switched to PLL mode (PLLEN = 1). The Main PLL lock time
is given in Table 7-62.

definitions can be found in the sections following the Table 7-63, for other registers in the table, see the Phase Locked
Loop (PLL) Controller for KeyStone Devices User Guide (literature number SPRUGV2).
CAUTION—Note that only registers documented here are accessible on the TMS320C6674. Other addresses
in the PLL controller memory map including the reserved registers should not be modified. 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. It is recommended to use read-modify-write sequence to
make any changes to the valid bits in the register.

ADVANCE INFORMATION
The Main PLL controller has two modes of operation: bypass mode and PLL mode. The mode of operation is
determined by the PLLEN bit of the PLL control register (PLLCTL). In PLL mode, REFCLK is generated from the
PLL output using the divider POSTDIV and the PLL multiplier PLLM. In bypass mode, PLL output is fed directly
to REFCLK.

7.8.2.7 Reset Control Register (RSTCTRL)
This register contains a key that enables writes to the MSB of this register and the RSTCFG register. The key value
is 0x5A69. A valid key will be stored as 0x000C, any other key value is invalid. When the RSTCTRL or the RSTCFG
is written, the key is invalidated. Every write must be set up with a valid key. The Software Reset Control register
(RSTCTRL) is shown in Figure 7-30 and described in Table 7-70.

7.8.3 Main PLL Control Register
The Main PLL uses a chip-level register (MAINPLLCTL) along with the PLL controller for its configuration. This
MMR exists inside the Bootcfg space. To write to this register, software should go through an un-locking sequence
using KICK0/KICK1 registers. For valid configurable values into the MAINPLLCTL register see Section 2.5.3 ‘‘PLL
Boot Configuration Settings’’ on page 31. See section 3.3.4 ‘‘Kicker Mechanism (KICK0 and KICK1) Register’’ on
page 66 for the address location of the registers and locking and unlocking sequences for accessing the registers. This
register is reset on POR only.

7.9 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 (literature number
SPRABI2). 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).

7.9.2 DDR3 PLL Device-Specific Information
As shown in Figure 7-36, 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 7.7 ‘‘Reset Controller’’ on page 202. 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.

7.10 PASS PLL
The PASS PLL generates interface clocks for the Packet Accelerator Subsystem. Using the PACLKSEL pin the user
can select the input source of PASS PLL as either the output of Main PLL mux 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.
ADVANCE INFORMATION
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 (literature

7.10.2 PASS PLL Device-Specific Information
As shown in Figure 7-39, the output of PASS PLL (PLLOUT) is divided by 2 and directly fed to the Packet
Accelerator Sub-System. The PASS PLL is affected by power-on reset. During power-on resets, the internal clocks
of the PASS PLL are affected as described in Section 7.7 ‘‘Reset Controller’’ on page 202. PASS 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.

TMS320C6674
Multicore Fixed and Floating-Point Digital Signal Processor
SPRS692—November 2010

7.11 DDR3 Memory Controller
The 64-bit DDR3 Memory Controller bus of the TMS320C6674 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 TMS320C6674 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.
ADVANCE INFORMATION
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 indication that the write
completes, 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) 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.
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 (literature number SPRABI1)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.
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.

7.12.1 I C Device-Specific Information
2
2
The TMS320C6674 device includes an I C peripheral module. 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 C6674 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
The I C port supports:
2
• Compatible with Philips I C specification revision 2.1 (January 2000)
• 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.

ADVANCE INFORMATION
The universal asynchronous receiver/transmitter (UART) module provides an interface between the DSP and
UART terminal interface or other UART based peripheral. 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.

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 TMS320C6674 device has eight 64-bit timers in total. Of which Timer0 through Timer3 are dedicated to each
of the four CorePacs as a watchdog timer and can also be used as general-purpose timers. Each of other 4 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.
ADVANCE INFORMATION
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 zero 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
zero, the timer event output is asserted. Reset initiated by a watch dog timer can be set by programming ‘‘Reset Type
Status Register (RSTYPE)’’ on page 215 and the type of reset initiated can set by programming ‘‘Reset Configuration
Register (RSTCFG)’’ on page 217. For more information, see the 64-bit Timer (Timer 64) for KeyStone Devices User
Guide (literature number SPRUGV5).

The SRIO port on the TMS320C6674 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 (literature number
SPRUGW1).

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:
•
•
244
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
The TMS320C6674 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:
• Using Advanced Event Triggering to Find and Fix Intermittent Real-Time Bugs application report (literature
number SPRA753)

The C6674 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 (literature number SPRU655).

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 C6674 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.
