Description
The TMS320C64x+ DSPs (including the TMS320C6474 device) are the highest-performance multicore
DSP generation in the TMS320C6000™ DSP platform.
The C6474 device is based on the third-generation high-performance, advanced VelociTI™
very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI).
The C64x+™ devices are upward code-compatible from previous devices that are part of the C6000™
DSP platform.
1.2.1
Core Processor
Based on 65-nm process technology and 3.6 GHz of total raw DSP processing power with performance of
up to 28,800 million instructions per second (MIPS) [or 28,800 16-bit MMACs per cycle], the C6474 device
offers cost-effective solutions to high-performance DSP programming challenges with three independent
DSP subsystems. The DSP possesses the operational flexibility of high-speed controllers and numerical
capability of array processors.
The C64x+ DSP core employs eight functional units, two register files, and two data paths. Like the earlier
C6000 devices, two of these functional units are multipliers or .M units. Each C64x+ .M unit doubles the
multiply throughput versus the C64x core by performing four 16-bit x 16-bit multiply-accumulates (MACs)
every clock cycle. Thus, eight 16-bit x 16-bit MACs can be executed every cycle on the C64x+ core. At
a1.2-GHz rate, this means 9600 16-bit MMACs can occur every microsecond. Moreover, each multiplier
on the C64x+ core can compute one 32-bit x 32-bit MAC or four 8-bit x 8-bit MACs every clock cycle.
The C6474 DSP integrates a large amount of on-chip memory organized as a three-level memory system.
The level-1 data memories on the device are 32 KB each. This memory can be configured as mapped
RAM, cache, or some combination of the two. When configured as cache, L1 program (L1P) is a
direct-mapped cache where as L1 data (L1D) is a two-way set associative cache. The level-3 (L3) ROM is
64 KB in the device. The C64x+ megamodule also has a 32-bit peripheral configuration (CFG) port, an
internal DMA (IDMA) controller, a system component with reset/boot control, and a free-running 32-bit
timer for time stamp.
The C64x+ DSP core has a complete set of development tools which includes: a new C compiler, an
assembly optimizer to simplify programming and scheduling, and a Windows® debugger interface for
visibility into source code execution.
The DMA switch fabric provides enhanced on-chip connectivity between the DSP cores and the
peripherals and accelerators.
1.2.2
Peripherals
The peripheral set includes: an inter-integrated circuit bus module (I2C); two multichannel buffered serial
ports (McBSPs) each at 100 Mbps; six 64-bit general-purpose timers (also configurable as twelve 32-bit
timers); 16 general-purpose input/output ports (GPIO) with programmable interrupt/event generation
modes; a 1000-Mbps Ethernet media access controller (EMAC), which provides an efficient interface
between the C6474 DSP core processor and the network; a management data input/output (MDIO)
module (also part of EMAC), which controls PHY configuration and status monitoring; a frame
synchronization (FSYNC) module, which synchronizes DMA transactions; a semaphore hardware block
(Semaphore), which allows access to shared resources with unique interrupts to each of the cores to
identify when that core has acquired the resource; and a 16-/32-bit DDR2 SDRAM interface.
The I2C port allows the DSP to easily control peripheral devices and communicate with a host processor.

SPRS552H – OCTOBER 2008 – REVISED APRIL 2011
www.ti.com
The device includes two Serial RapidIO® (SRIO) with link rates of 1.25 Gbps, 2.5 Gbps or 3.125 Gbps.
This high-bandwidth peripheral is used for point-to-point inter-device communication and may connect the
C6474 device to other DSPs, ASICs, or switches on the same board or across the backplane. This
dramatically improves system performance and reduces system cost for applications that include multiple
DSPs on a board such as video and telecom infrastructures and medical/imaging. The SRIO also provides
alarm, interrupt, and messaging events.
The device includes the SerDes-based antenna interface (AIF) capable of up to 3.072 Gbps operation per
link. The AIF comprises six high-speed serial links, compliant to OBSAI RP3 and CPRI standards. The
antenna interface is used to connect the backplane for antenna data transmission and reception. Each link
of the AIF includes a differential receive and transmit signal pair.
1.2.3
Accelerators
The device has two high-performance embedded coprocessors [enhanced Viterbi Decoder Coprocessor
(VCP2) and enhanced turbo decoder coprocessor (TCP2)] that significantly speed up channel-decoding
operations on-chip. The VCP2 operating at CPU clock divided-by-3 can decode over 694 7.95-Kbps
adaptive multi-rate (AMR) [K=9, R=1/3] voice channels. The VCP2 supports constraint lengths K = 5, 6, 7,
8, and 9, rates R = 3/4, 1/2, 1/3, and 1/5, and flexible polynomials, while generating hard decisions or soft
decisions. The TCP2 operating at CPU clock divided-by-3 can decode up to fifty 384-Kbps or eight
2-Mbps turbo encoded channels (assuming 6 iterations). The TCP2 implements the max*log-map
algorithm and is designed to support all polynomials and rates required by third-generation partnership
projects (3 GPP and 3 GPP2), with fully programmable frame length and turbo interleaver. Decoding
parameters such as the number of iterations and stopping criteria are also programmable.
Communications between the VCP2/TCP2 and the CPU are carried out through the EDMA3 controller.

CPU (DSP Core) Description
The C64x+ central processing unit (CPU) 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 (thirty-two)
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, 32-bit data, 40-bit data, and
64-bit data. Values larger than 32 bits, such as 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).
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.
The C64x+ CPU extends the performance of the C64x core through enhancements and new features.
Each C64x+ .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, two 16 x
16 bit multiplies, two 16 x 32 bit multiplies, four 8 x 8 bit multiplies, four 8 x 8 multiplies with add
operations and four 16 x 16 multiplies with add/subtract capabilities (including a complex multiply). There
is also support for Galois filed multiplication for 8-bit and 32-bit data. Many communications algorithms
such FFTs and modems require complex multiplication. The complex multiply (CMPY) instruction takes
four 16-bit inputs and produces a 32-bit real and a 32-bit imaginary output. There are also complex
multiplies with rounding capability that produces one 32-bit packed output that contain 16-bit real and
16-bit imaginary values. The 32 x 32 bit multiply instructions provide the extended precision necessary for
audio and other high-precision algorithms on a variety of signed and unsigned 32-bit data types.
The .L or arithmetic logic unit now incorporates the ability to do parallel add/subtract operations on a pair
of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data
performing dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions.
The C64x+ core enhances the .S unit in several ways. In the C64x core, dual 16-bit MIN2 and MAX2
comparisons were only available on the .L units. On the C64X+ core, they are also available on the .S unit
which increases the performance of algorithms that do searching and sorting. Finally, to increase data
packing and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bit
and dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Pack
instructions return parallel results to output precision including saturation support.
Other new features include:
• SPLOOP - a small instruction buffer in the CPU that aids in creation of software pipelining loops where
multiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code size
associated with software pipelining. Furthermore, loops in the SPLOOP buffer are fully interruptible.
• Compact Instructions - The native instruction size of the C6000 devices is 32 bits. Many common
instructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C64x+
compiler can restrict the code to use certain registers in the register file. This compression is
performed by the code generation tools.

Instruction Set Enhancements - As noted above, there are new instructions such as 32-bit
multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field
multiplication.
Exception Handling - Intended to aid the programmer in isolating bugs. The C64x+ CPU is able to
detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and
from system events (such as watchdog time expiration).
Privilege - Defines user and supervisor modes of operation, allowing the operating system to give a
basic level of protection to sensitive resources. Local memory is divided into multiple pages, each with
read, write, and execute permissions.
Time-Stamp Counter - Primarily targeted for real-time operating system (RTOS) robustness, a
free-running time-stamp counter is implemented in the CPU that is not sensitive to system stalls.
For more details on the C64x+ CPU and its enhancements over the C64x architecture, see the following
documents:

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 C64x+ Megamodule should not affect the state of the hardware boot controller on the device.
For more details on the initiators of the resets, see Section 7.7, Reset Controller.
The C6474 device supports several boot processes 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; using the BOOTMODE[3:0] device configuration inputs to determine the software
configuration that must be completed.
2.4.1
Boot Modes Supported
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 three possible boot modes:
• No Boot (BOOTMODE[3:0] = 0000b)
With no boot, the CPU executes directly from the internal L2 RAM located at address 0x80 0000.
Note: Device operations are undefined if invalid code is located at address 0x80 0000. This boot mode
is a hardware boot mode.
• Public ROM Boot
The C64x+ Megamodule Core 0 is released from reset and begins executing from the L3 ROM base
address. C64x+ Megamodule Core 0 is responsible for performing the boot process (e.g., from I2C
ROM, Ethernet, or RapidIO), after which C64x+ Megamodule Core 0 brings the other C64x+
megamodule cores out of reset by setting to 1 the EVTPULSE4 bit (bit 4) of the C64x+ Megamodule
Core 0's EVTASRT register. This process is valid only once: writing 1, then writing 1 again will not
bring Core 1 and 2 out of reset again. Then, the C64x+ Megamodule Core 0 begins execution from the
entry address defined in the boot table. The C64x+ Megamodule Core 1 and 2 begin execution from
their L2 RAMs' base address.
The boot process performed by C64x+ Megamodule Core 0 in public ROM boot is determined by the
BOOTMODE[3:0] value in the DEVSTAT register. C64x+ Megamodule Core 0 reads this value, and then
executes the associated boot process in software.

Table 2-3. C6474 Supported Boot Modes
MODE NAME
BOOTMODE[3:0]
DESCRIPTION
No Boot
0000b
No Boot (BOOTMODE[3:0] = 0000b)
I2C Master Boot A
0001b
Slave I2C address is 0x50. C64x+ Megamodule Core 0 configures I2C, acts as a
master to the I2C bus and copies data from an I2C EEPROM or a device acting as an
I2C slave to the DSP using a predefined boot table format. The destination address
and length are contained within the boot table. After boot table copy is complete, the
C64x+ Megamodule Core 0 brings the other C64x+ Megamodule Cores out of reset
by setting to 1 the EVTPULSE4 bit (bit 4) of the C64x+ Megamodule Core EVTASRT
register.
I2C Master Boot B
0010b
Similar to I2C boot A except the slave I2C address is 0x51.
I2C Slave Boot
0011
The C64x+ Megamodule Core 0 configures I2C and acts as a slave and will accept
data and code section packets through the I2C interface. It is required that an I2C
master in present in the system.
EMAC Master Boot
0100b
EMAC Slave Boot
0101b
EMAC Forced-Mode Boot
0110b
TI Ethernet Boot, C64x+ Megamodule Core 0 configures EMAC0 and EDMA, if
required, and brings the code image into the internal on-chip memory via the protocol
defined by the boot method (EMAC bootloader). After initializing the on-chip memory
to the known state, C64x+ Megamodule Core 0 brings the other C64x+ Megamodule
Cores out of reset.

The C64x+ Megamodule Core 0 configures the SRIO and an external host loads the
application via SRIO peripheral, using directIO protocol. A doorbell interrupt is used to
indicate that the code has been loaded. For more details on the Serial RapidIO
configurations, see Table 2-4.
Serial RapidIO Boot (Config 3)
1011b
C64x+ Megamodule Core 0 configures Serial RapidIO and EDMA, if required, and brings the code image
into the internal on-chip memory via the protocol defined by the boot method (SRIO bootloader) and then
C64x+ Megamodule Core 0 brings the other C64x+ Megamodule Cores out of reset. Note that SRIO boot
modes are only supported on port 0.

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.

Non-maskable interrupts. NMI0, NMI1, and NMI2 pins are mapped to C64x+
Megamodule Core 0, C64x+ Megamodule Core 1, and C64x+ Megamodule Core
2, respectively. NMIs are edge-driven (rising edge). Any noise on the NMI pin
may trigger an NMI interrupt; therefore, if the NMI pin is not used, it is
recommended that the NMI pin be grounded rather than relying on the IPD.

Development and Device Support
Development Support
In case the customer would like to develop their own features and software on the C6474 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) Evaluation Module (EVM).
2.8.2
Device 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., TMS320C6474ZUN). 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 against 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 C6474 device, certain device configurations (like boot mode, pin multiplexing, and endianness) are
selected at device reset. The status of the peripherals (enabled/disabled) is determined after device reset.
By default, the peripherals on the device are disabled and must be enabled by software before being
used.
3.1
Device Configuration at Device Reset
Table 3-1 describes the C6474 device. The logic level is latched at reset to determine the device
configuration. The logic level can be set by using external pullup/pulldown resistors or by using some
control device to intelligently drive these pins. When using a control device, take care to avoid contention
on the lines when the device is out of reset. The are sampled during power-on reset and are driven after
the reset is removed. To avoid contention, the control device must stop driving the of the DSP.
NOTE
If a configuration pin must be routed out from the device, the internal pullup/pulldown
(IPU/IPD) resistor should not be relied upon; TI recommends the use of an external
pullup/pulldown resistor.

ALTCORECLK is used as the input to PLLCTL1 and SYSCLK is used only for the
Antenna Interface.
Peripheral Selection After Device Reset
Several of the peripherals on the C6474 device are controlled by the Power/Sleep Controller (PSC). By
default the AIF, SRIO, TCP, and VCP are held in reset and clock-gated. The memories in these modules
are also in a low-leakage sleep mode. Software will be required to turn these memories on then enable
the modules (turn on clocks and de-assert reset) before these modules can be used.
If one of the above modules is used in the selected boot mode, the ROM code will automatically enable
the used 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 TMS320C6474 DSP Power/Sleep Controller
(PSC) User's Guide (literature number SPRUG10).

Inter-DSP Interrupt Registers (IPCGR0-IPCGR2 and IPCAR0-IPCAR2)
The IPCGRn (IPCGR0 thru IPCGR2) and IPCARn (IPCAR0 thru IPCAR2) registers facilitate inter-DSP
interrupts. This can be utilized by external hosts or C64x+ megamodules to generate interrupts to other
DSPs. A write of 1 to the IPCG field of IPCGRn register generates an interrupt pulse to C64x+
Megamodulen (n = 0-2). These registers also provide a source ID, by which up to 28 different sources of
interrupts can be identified.

Debugging Considerations
It is recommended that external connections be provided to device configuration pins. Although internal
pullup/pulldown resistors exist on these pins, providing external connectivity adds convenience to the user
in debugging and flexibility in switching operating modes.
For the internal pullup/pulldown resistors for all device pins, see Table 2-5.

4 System Interconnect
On the C6474 device, the C64x+ Megamodule, 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. Through a switch fabric the
CPU can send data to the Viterbi co-processor (VCP2) without affecting a data transfer through the DDR2
memory controller. The switch fabrics also allow for seamless arbitration between the system masters
when accessing system slaves.
4.1
Internal Buses, Switch Fabrics, and Bridges/Gaskets
Two types of buses exist in the C6474 device: data buses and configuration buses. Some C6474
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. For example, data is transferred to the VCP2 and TCP2 via their configuration bus interface.
Similarly, the data bus can also be used to access the register space of a peripheral. For example, the
DDR2 memory controller registers are accessed through their data bus interface.
The C64x+ megamodule, the EDMA3 transfer 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 include the EDMA3
transfer controllers, SRIO, and EMAC. Examples of slaves include the McBSP and I2C.
The C6474 device contains two switch fabrics 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 4.3). The SCR adds no
latency and allows seamless arbitration (i.e., no dead cycles inserted by the fabric) between the masters
and slaves. The data SCR connects masters to slaves via 128-bit data buses (SCR B) and 64-bit data
buses (SCR A) running at a CPU/3 frequency (CPU/3 is generated from PLL1 controller). Peripherals that
have a 128-bit data bus interface running at this speed 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 by the C64x+ Megamodule to access peripheral registers (for more information, see Section 4.4).
The configuration SCR connects C64x+ Megamodule to slaves via 32-bit configuration buses running at a
CPU/3 frequency (CPU/3 is generated from PLL1 controller). As with the data SCR, some peripherals
require the use of a bridge to interface to the configuration SCR. Note that the data SCR also connects to
the configuration SCR.
Bridges and gaskets are required to perform a variety of functions. For the purpose of this document,
bridges and gaskets can be considered as identical. Within the switch fabric infrastructure, gaskets are
simpler than bridges in that they only modify control signals to convert protocols. 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.
For more information on the common bus architecture and its throughput in the C6474 device, see the
TMS320C6474 Common Bus Architecture Throughput application report (literature number SPRAAX6)
and the TMS320C6474 Module Throughput application report (literature number SPRAAW5).

Data Switch Fabric Connections
Figure 4-1 shows the DMA switch fabric, including the EDMA3, connection between slaves and masters
through the data switched central resource (SCR). Masters are shown on the right and slaves on the left.
The number of master ports for the EDMA is 2x the number of TPTCs implemented because each TPTC
has a read port and a write port.

Not all masters on the C6474 DSP may connect to slaves. Allowed connections are summarized in
Table 4-1 and Table 4-2.
SCR A is the main 128-bit switch fabric, which includes the slave ports of all C64x+ Megamodules. There
are three dedicated, 128-bit TPTC channels for internal memory-to-memory transfers, though the channels
can be used to access anything on SCR B as well. Note that any module accessing these particular
C64x+ Megamodules ports, including the EDMA, must use the global addresses, not the local addresses.
The Antenna Interface (AIF) is connected to the SCR via a special bridge that separates the read and
write interfaces into individual ports. The AIF is fully accessible to TPTC channels 3, 4, and 5, allowing
antenna data to be transferred between the AIF and any DSP memory.
Two of the SCR slave ports are driven by masters from SCR B, allowing data to be transferred between
the device peripherals and L2 memory.

SCR B is a secondary, 64-bit switch fabric, primarily dedicated to slave peripherals that require servicing
by the TPDMA. Additionally, master peripherals that are sub-128 bit are connected to this switch fabric.
There are two master ports on the SCR that allow masters to send commands to any of the slaves on
SCR A. There are three TPTC channels directly connected to SCR B to service the slave peripherals.
The Ethernet MAC (EMAC) is connected to the switch fabric with a pair of bridges to convert from VBUSP
to VBUSM (Br 6), along with a change in the bus width and frequency (Br 7). The Br 7 handles a majority
of this conversion, with the Br 6 bridge serving as a protocol-conversion gasket.
The RapidIO CPPI port is connected to the switch fabric similarly to the EMAC connection. This enables
RapidIO to use L2 or DDR2 for buffer descriptors. RapidIO is connected directly to the switch fabric and
can master any memory.
The DDR EMIF is also directly connected as a slave, allowing any master full access to the external
memory space.

Priority Allocation
On the C6474 device, each of the masters is assigned a priority via the Priority Allocation Register
(PRI_ALLOC), see Figure 4-3. User-programmable priority registers allow software configuration of the
data traffic through the SCR. The priority is enforced when several masters in the system vie for the same
endpoint. The PRI value of 000b has the highest priority, while the PRI value 111b has the lowest priority.
A chip-level register must be provided to set these values for masters that do not have their own register
internally.
The configuration SCR port on the data SCR is considered a single endpoint meaning priority will be
enforced when multiple masters try to access the configuration SCR. Priority is also enforced on the
configuration SCR side when a master (through the data SCR) tries to access the same endpoint as the
C64x+ Megamodule.
The 4-Byte PRI_ALLOC register address range is 0288 083C - 0288 083F.

All other master peripherals are not present in the PRI_ALLOC register, as they have their own registers
to program their priorities and do not need a default priority setting. For more information on the default
priority values in these peripheral registers, see the device-compatible peripheral reference guides. TI
recommends that these priority registers be reprogrammed upon initial use.

Memory Architecture
The C6474 device contains a 3MB level-2 memory (L2) total, a 32KB level-1 program memory (L1P) per
core, and a 32KB level-1 data memory (L1D) per core. All memory has a unique location in the memory
map and can be directly accessed by any master on the device.
The L1P memory configuration for the device is as follows:
• Region 0 size is 0K bytes (disabled).
• Region 1 size is 32K bytes with no wait states.
The L1D memory configuration for the device is as follows:
• Region 0 size is 0K bytes (disabled).
• Region 1 size is 32K bytes with no wait states.
After core 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 (L1PMODE)
and the L1DMODE field of the L1D Configuration Register (L1DCFG) of the C64x+ Megamodule. L1D is a
two-way set-associative cache while L1P is a direct-mapped cache.
L1P and L1D are configured as memory-mapped SRAM, rather than only unmapped cache. Though
all-cache is the default configuration after device reset, the amount of cache for L1P and L1D may be
programmed to be 0Kb, 4Kb, 8Kb, 16Kb, or 32Kb. All additional L1P or L1D memory space is
memory-mapped SRAM. Figure 5-2 provides the memory mapping of L1P. Figure 5-2 provides the
memory mapping of L1D. L1P SRAM and L1D SRAM begin at the same address regardless of the SRAM
size configured.

All memory on the device has a unique location in the memory (see Section 2.3, Memory Map Summary).
Global addresses that are accessible to all masters in the system are in all memory local to the
processors. Additionally, 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 C64x+
Megamodule and allows for common code to be run unmodified on multiple cores. For example, address

location 0x10800000 is the global base address for C64x+ Megamodule Core 0's L2 memory. C64x+
Megamodule 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
three cores as their own L2 base addresses. For C64x+ Megamodule Core 0, as mentioned this is
equivalent to 0x10800000, for C64x+ Megamodule Core 1 this is equivalent to 0x11800000, and for
C64x+ Megamodule Core 2 this is equivalent to 0x12800000. Local addresses should only be used 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.
5.3
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 up to 64 pages of L2. The L1D, L1P, and L2
memory controllers in the C64x+ Megamodule are equipped with a set of registers that specify the
permissions for each memory page. For L2, the number of protection pages and their sizes depend on the
L2 configuration of the device, as defined in the previous section. The actual sizes are listed in Table 5-1.

Each page may be assigned with fully orthogonal user and supervisor read, write, and execute
permissions. Additionally, a page may be marked as either (or both) locally or globally accessible. A local
access is one initiated by the CPU, while a global access is initiated by a DMA (either IDMA or DMA
access by any C64x+ Megamodule or master peripheral).
The CPU and each of the system masters on the device are all assigned a privilege ID (see Table 5-3).
The AIDx (x=0,1,2,3,4,5) and LOCAL bits of the memory protection page attribute registers specify the
memory page protection scheme as listed in Table 5-4.
Whenever the CPU is the initiator of a memory transaction, the privilege mode (user or supervisor) in
which the CPU is running at that time is carried with those transactions. This includes EDMA3 transfers
that are programmed by the CPU. Other system masters (EMAC, RapidIO) are always in user mode.

Faults are handled by software in an interrupt (or exception, programmable within each C64x+
Megamodule interrupt controller) service routine. A CPU or DMA access to a page without the proper
permissions will:
• Block the access - reads return zero, writes are voided.
• Capture the initiator in a status register - ID, address, and access type are stored.
• Signal event to CPU interrupt controller.
The software is responsible for taking corrective action to respond to the event and resetting the error
status in the memory controller.
5.4
Bandwidth Management
When multiple requesters contend for a single C64x+ Megamodule resource, the conflict is solved 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 C64x+ Megamodule; e.g., CPU-initiated transfers,
user-programmed cache coherency operations, and IDMA-initiated transfers, are declared through
registers in the C64x+ Megamodule. The priority level for operations initiated outside the C64x+
Megamodule by system peripherals is declared through the Priority Allocation Register (PRI_ALLOC), see
Section 4.4. System peripherals with no fields in PRI_ALLOC have their own registers to program their
priorities.
Table 5-5 shows the default priorities of all masters in the device.

Power-Down Control
The C64x+ Megamodule supports the ability to power-down various parts of the C64x+ Megamodule. The
power-down controller (PDC) of the C64x+ Megamodule can be used to power down L1P, the cache
control hardware, the CPU, and the entire C64x+ Megamodule. These power-down features can be used
to design systems for lower overall system power requirements. Note that the device does not support
power-down modes for the L2 memory at this time.

C64X+ Megamodule Register Description(s)
In some applications, some specific addresses may need to be read from their physical locations each
time they are accessed (e.g., a status register within FPGA).
The L2 controller offers registers that control whether certain ranges of memory are cacheable and
whether one or more requestors are actually permitted to access these ranges. The registers are referred
to as memory attribute registers (MARs). A list of MARs is provided in Table 5-12.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to VSS.
There is no pin named DVDD11 available on the device. DVDD11 represents the AIF_VDDA11, AIF_VDDD11, AIF_VDDT11, SGR_VDDA11,
SGR_VDDD11, and SGR_VDDT11 pins.
A heatsink is required for proper device operation.
Advance Information is presented in this document for the C6474 1.2-GHz extended temperature device.

The data sheet 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's guides, and design guides.
A transmission line delay of 2 ns was used for all output measurements, except the DDR2 which was evaluated using
a 528-ps delay.
This figure represents all outputs, except differential or I2C.

7.3.2
Power-Supply Decoupling
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as
possible close to the DSP. These caps need to be close to the DSP, no more than 1.25 cm maximum
distance to be effective. Physically smaller caps are better, such as 0402, but need to be evaluated from a
yield/manufacturing point-of-view. Parasitic inductance limits the effectiveness of the decoupling
capacitors, therefore physically smaller capacitors should be used while maintaining the largest available
capacitance value. As with the selection of any component, verification of capacitor availability over the
product's production lifetime should be considered.
7.3.3
Power-Down Operation
One of the power goals for the C6474 device is to reduce power dissipation due to unused peripherals.
There are different ways to power down peripherals on the C6474 device.

Some peripherals can be statically powered down at device reset through the device configuration pins
(see Section 3.1, Device Configuration at Device Reset). Once in a static power-down state, the peripheral
is held in reset and its clock is turned off. Peripherals cannot be enabled once they are in a static
power-down state. To take a peripheral out of the static power-down state, a device reset must be
executed with a different configuration pin setting.
After device reset, all peripherals on the C6474 device are in a disabled state and must be enabled by
software before being used. It is possible to enable only the peripherals needed by the application while
keeping the rest disabled. Note that peripherals in a disabled state are held in reset with their clocks
gated. For more information on how to enable peripherals, see Section 3.2, Peripheral Selection After
Device Reset.
Peripherals used for booting, like I2C, are automatically enabled after device reset. It is possible to disable
peripherals used for booting after the boot process is complete. This, too, results in gating of the clock(s)
to the powered-down peripheral. Once a peripheral is powered-down, it must remain powered down until
the next device reset.
The C64x+ Megamodule also allows for software-driven power-down management for all of the C64x+
Megamodule components through its Power-Down Controller (PDC). The CPU can power-down part or
the entire C64x+ Megamodule through the power-down controller based on its own execution thread or in
response to an external stimulus from a host or global controller. More information on the power-down
features of the C64x+ Megamodule can be found in the TMS320C64x+ Megamodule Reference Guide
(literature number SPRU871).

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 C6474 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 C6474 device.
To guarantee maximizing performance and minimizing power consumption of the device, SmartReflex is
required to be implemented whenever the C6474 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 complete information on SmartReflex, see the TMS320C6474 Hardware Design
Guide application report (literature number SPRAAW7).

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 such as a McBSP port, and
offloads data transfers from the device CPU.
The EDMA3 includes the following features:
• Fully orthogonal transfer description
– 3 transfer dimensions: array (multiple bytes), frame (multiple arrays), and 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
• 256 PaRAM entries
– Used to define transfer context for channels
– Each PaRAM entry can be used as a DMA entry, QDMA entry, or link entry
• 64 DMA channels
– 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
– Used for software-driven transfers
– Triggered upon writing to a single PaRAM set entry
• 6 transfer controllers and 6 event queues with programmable system-level priority
• 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
Each of the transfer controllers has a direct connection to the switched central resource (SCR). Table 4-1
lists the peripherals that can be accessed by the transfer controllers.

EDMA3 Channel Synchronization Events
The EDMA3 supports up to 64 DMA channels 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. Table 7-4 lists the source of the synchronization event associated with each of the
DMA channels. The association of each synchronization event and DMA channel is fixed and cannot be
reprogrammed. Additional events are available to the EDMA3 via an external interrupt controller. For more
details on Chip Interrupt Controller 3 (CIC3), see Section 7.6.2.

Interrupts
7.6.1
Interrupt Sources and Interrupt Controller
The CPU interrupts on the device are configured through the C64x+ Megamodule Interrupt Controller. The
interrupt controller allows for up to 128 system events to be programmed to any of the twelve CPU
interrupt inputs, the CPU exception input, or the advanced emulation logic. Table 7-13 shows the mapping
of system events to the interrupt controller inputs. Event numbers 0-31 correspond to the default interrupt
mapping of the device. The remaining events must be mapped using software. Table 7-14 lists the Chip
Interrupt Controller (CIC) registers. For more details on chip interrupt controller 0-2 (CIC0, CIC1, and
CIC2), see Section 7.6.2.

System Event Routing
Additional system events are routed to each of the C64x+ Megamodules 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 C64x+ Megamodule interrupt selector. This is accomplished through Chip Interrupt
Controllers, CIC[2:0], with one controller per C64x+ Megamodule. This is clocked using CPU/6.
The event controllers consist of simple combination logic to provide sixteen events to each C64x+
Megamodule, plus the TPCC.
These events are routed to the C64x+ Megamodules for AET purposes, from those TPCC and FSYNC
events that are not otherwise provided to each C64x+ Megamodule. The event controllers each include
two event combiners to provide two combined events to each C64x+ Megamodule, for use. Each of the 16
event outputs from the controllers can select any of the 64 inputs, or either of the two combined events to
pass on to their respective C64x+ Megamodule.
Table 7-15 lists the system events that are available to each C64x+ Megamodule through their respective
event controllers. Note that n implies the event number matches the C64x+ Megamodule number to which
it is routed.

Another system event selector is present to route events to the TPCC. Most system events routed through
the event controller to the TPCC are CPU events that do not normally require DMA servicing, but may be
used to trigger a statistics capture. Several events are routed through the event controller that may be
used to trigger a DMA transaction in normal operation, but the programmer must make a resource tradeoff
to use these events. Table 7-16 lists all of the events routed through the TPCCs system event controller.

Reset Controller
The reset controller detects the different type of resets supported on the device and manages the
distribution of those resets throughout the device.
The C6474 device has several types of resets: power-on reset, warm reset, system reset, and CPU reset.
Table 7-18 explains further the types of reset, the reset initiator, and the effects of each reset on the chip.
Table 7-18. Reset Types
TYPE
INITIATOR
EFFECT(S)
Power-on Reset
POR pin
Resets the entire chip including the test and emulation logic.
Warm Reset
XWRST pin
Resets everything except for the test and emulation logic PLL2, AIF, and FSYNC. Emulation
stays alive during warm reset.
System Reset
Emulator
Serial RapidIO
A system reset maintains memory contents and does not reset the test and emulation
circuitry. The device configuration pins are also not re-latched and the state of the
peripherals (enabled/disabled) are also not affected.
CPU Local Reset
Watchdog Timer
CPU local reset.
7.7.1
Power-on Reset (POR Pin)
Power-on Reset is a special reset needed when powering on the DSP. The device is globally reset
through the assertion of the active-low Power-on Reset (POR) input. The power-on reset is intended to be
asserted to the device while the system power supplies are ramped.
For power-on reset, the main PLL Controller comes up in bypass and the PLL is not enabled. Other resets
do not affect the state of the PLL or the dividers in the PLL Controller. For the secondary PLL Controller,
this is different as the PLL is enabled and clocking always when POR is not asserted.
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 3.2, Peripheral
Selection After Device Reset.
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 100
μs.
4. The POR pin can now be de-asserted. Reset sampled pin values are latched at this point. PLL2 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,
PLL2 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.

7.7.2
SPRS552H – OCTOBER 2008 – REVISED APRIL 2011
Warm Reset
A warm reset will reset everything on the chip except the AIF, FSYNC, PLLs, PLL Controllers, test, and
emulation logic. POR should also remain de-asserted during this time.
1. XWRST pin is pulled active low for a minimum of 24 CLKIN1 cycles. The reset signals flow to the
modules reset by warm reset and sends a tri-state signal to most the I/O pads, to prevent off chip
contention.
2. Once all logic is reset, RESETSTAT is driven active to denote that the device is in reset.
3. XWRST 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).
During warm reset, the DDR2 SDRAM memory content can be retained if the user places the DDR2
SDRAM in self-refresh mode before invoking the warm reset; however, warm reset will reset the DDR2
EMIF registers. The software needs to re-program all DDR2 EMIF registers to correct values after warm
reset.
7.7.3
System Reset
System reset is initiated by the emulator or by the RapidIO module. It is triggered by clicking on the
Debug → Advanced Resets → System Reset menu in Code Composer Studio using the emulator.
System reset is also triggered by RIOINT[6], which is connected to the reset controller. It is considered a
soft reset, meaning memory contents are maintained, it does not affect the clock logic, or the power
control logic of the peripherals.
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. The boot sequence is started after the system clocks are restarted. Since the configuration pins
(including the BOOTMODE[3:0] 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
CPU Reset
(Timer 64 3, 4, and 5) can provide a local CPU reset if they are setup in watchdog mode. Timer64 3, 4,
and 5 are allowed to reset C64x+ Megamodule Core 0, C64x+ Megamodule Core 1, and C64x+
Megamodule Core 2, respectively.
7.7.5
Reset Priority
If any of the above reset sources occur simultaneously, the PLLCTRL only processes the highest priority
reset request. The reset request priorities are as follows (high to low):
• Power-on Reset
• Warm Reset
• System Reset
• CPU Reset

PLL1 and PLL1 Controller
This section provides a description of the PLL1 controller registers. For details on the operation of the PLL
controller module, see the TMS320C6474 DSP Software-Programmable Phase-Locked Loop (PLL)
Controller User's Guide (literature number SPRUG09).
Note: The PLL1 controller registers can only be accessed using the CPU or the emulator.
Not all of the registers documented in the TMS320C6474 DSP Software-Programmable Phase-Locked
Loop (PLL) Controller User's Guide (literature number SPRUG09) are supported on the C6474 device.
Only those registers documented in this section are supported. Furthermore, only the bits within the
registers described here are supported. You should not write to any reserved memory location or change
the value of reserved bits.
The Main and DDR PLLs are controlled by standard PLL Controller peripherals. The PLL Controllers
manage the clock ratios, alignment, and gating for the system clocks to the chip. Figure 7-10 includes a
block diagram of the PLL Controller, and the two subsequent sections define the clocks and PLL
Controller parameters for each of the two standard PLLs.
The PLL controller logic is responsible for controlling all modes of the PLL through software, in terms
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.

PLL1 Controller Device-Specific Information
7.8.1.1
Internal Clocks and Maximum Operating Frequencies
The Main PLL, used to drive all of the cores, the switch fabric, and a majority of the peripheral clocks (all
but the DDR2 clocks) requires a PLL controller to manage the various clock divisions, gating, and
synchronization. The Main PLL controller has seven CPU/6 outputs that are listed below, along with the
clock description. Each CPU/6 has a corresponding divide that divides down the output clock of the PLL.
Note that dividers are not programmable unless explicitly mentioned in the description below.
• SYSCLK1 - SYSCLK6: Reserved.
• SYSCLK7: Full-rate clock for all C64x+ Megamodules.
• SYSCLK8: Reserved.
• SYSCLK9: 1/3-rate clock (chip_clk3) for the switch fabrics, CIC blocks, and fast peripherals (AIF,
SRIO, TCP, VCP, EDMA).
• SYSCLK10: 1/6-rate clock (chip_clk6) for other peripherals (PLL Controllers, McBSPs, Timer64s,
Semaphore, EMAC, GPIO, I2C, PSC) and L3 ROM.
• SYSCLK11: 1/n-rate clock (chip_clks) for an optional McBSP CLKS module input to drive the clock
generator. Default for this will be 1/10. This is programmable from /8 to /32, where this clock does not
violate the max clock of 100 MHz. This clock is also output to the SYSCLKOUT pin.
• SYSCLK12: 1/2-rate clock used to clock the L2 and L2 Powerdown Controller.
• SYSCLK13: 1/n-rate clock for trace. Default rate for this will be 1/6. This is programmable from /1 to
/32, where this clock does not violate the max of 333 MHz. Please note that the data rate on the trace
pins are 1/2 of this clock.
7.8.1.2
PLL1 Controller Operating Modes
The PLL1 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, SYSREFCLK is
generated from the device input clock CLKIN1 and the PLL multiplier PLLM. In bypass mode, CLKIN1 is
fed directly to SYSREFCLK.
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
PLL1 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
PLL1 reset time value, see Table 7-23.
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 the PLL controller can be switched to PLL mode (PLLEN = 1). The PLL1 lock
time is given in Table 7-24.

PLL2 and PLL2 Controller
The secondary PLL controller generates interface clocks for the DDR2 memory controller. The CLKIN2
input for PLL2 is DDRREFCLK. It is a differential clock input and is applied at the DDRREFCLKP and
DDRREFCLKN pins. When coming out of power-on reset, PLL2 is enabled and initialized.
As shown in Figure 7-21, the PLL2 controller features a PLL multiplier controller. The PLL multiplier is
fixed to a x10 multiplier rate.
PLL2 power is supplied externally via the PLL2 power supply (AVDD218). An external PLL filter circuit must
be added to AVDD218 as shown in Figure 7-21. The 1.8-V supply for the EMI filter must be from the same
1.8-V power plane supplying the I/O power-supply pin, DVDD18. TI requires EMI filter manufacturer Murata.
For more information on the external PLL filter or the EMI filter, see the TMS320C6474 Hardware Design
Guide application report (literature number SPRAAW7).
All PLL external components (capacitors and the EMI filter) should be placed as close to the C64x+ DSP
device as possible. For the best performance, TI requires that all the PLL external components be on a
single side of the board without jumpers, switches, or components other than the ones shown. For
reduced PLL jitter, maximize the spacing between switching signals and the PLL external components
(capacitors and the EMI filter). The minimum CLKIN2 rise and fall times should also be observed.

Internal Clocks and Maximum Operating Frequencies
As shown in Figure 7-21, the output of PLL2, PLLOUT, is divided by 2 and directly fed to the DDR2
memory controller. This clock is used by the DDR2 memory controller to generate DDR2CLKOUT0[P/N]
and DDR2CLKOUT1[P/N]. Note that, internally, the data bus interface of the DDR2 memory controller is
clocked by SYSCLK2 and PLL1 controller.
Note that there is a minimum and maximum operating frequency for DDRREFCLK and PLLOUT. The
clock generator and PLL multiplier must not be configured to exceed any of these constraints. For the PLL
clocks input and output frequency ranges, see Table 7-35. DDRREFCLK is a differential clock input to
PLL2 and is applied at the DDRREFCLKP and DDRREFCLKN pins.

7.9.1.2
PLL2 Controller Operating Modes
Unlike the PLL1 controller which can operate in by_pass and _PLL mode, the PLL2 controller only
operates in PLL mode. In this mode, SYSREFCLK is generated outside the PLL2 controller by dividing the
output by two.
The PLL2 controller is affected by power-on reset and warm reset. During these resets, the PLL2
controller registers get reset to their default values. The internal clocks of the PLL2 controller are also
affected as described in Section 7.7, Reset Controller.
PLL2 is only unlocked during the power-up sequence (see Section 7.7, Reset Controller) and is locked by
the time the RESETSTAT pin goes high. It does not lose lock during any of the other resets.

7.10 DDR2 Memory Controller
The 32-bit DDR2 Memory Controller bus of the C6474 device is used to interface to JESD79-2B
standard-compliant DDR2 SDRAM devices. The DDR2 bus is designed to sustain a throughput of up to
2.67 GBps at a 667-MHz data rate (333-MHz clock rate) as long as data requests are pending in the
DDR2 Memory Controller.
The DDR2 external bus only interfaces to DDR2 SDRAM devices; it does not share the bus with any other
types of peripherals.
7.10.1 DDR2 Memory Controller Device-Specific Information
The approach to specifying interface timing for the DDR2 memory bus is different than on other interfaces
such as McBSP. 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 C6474 DDR2 memory bus, the approach is to specify compatible DDR2 devices and provide the
printed circuit board (PCB) solution and guidelines directly to the user. Texas Instruments (TI) has
performed the simulation and system characterization to ensure all DDR2 interface timings in this solution
are met. The complete DDR2 system solution is documented in the TMS320C6474 DDR2 Implementation
Guidelines application report (literature number SPRAAW8).
TI only supports designs that follow the board design guidelines outlined in the SPRAAW8
application report.
The DDR2 memory controller on the C6474 device supports the following memory topologies:
• 32-bit wide configuration interfacing to two 16-bit wide DDR2 SDRAM devices.
• 16-bit wide configuration interfacing to a single 16-bit wide DDR2 SDRAM device.
A race condition may exist when certain masters write data to the DDR2 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
hardware specification of write-read ordering, it may be necessary to specify data ordering via software.
If master A does not wait for an indication that a write is complete, it must perform the following
workaround:
1. Perform the required write.
2. Perform a dummy write to the DDR2 memory controller module ID and revision register.
3. Perform a dummy read to the DDR2 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 I2C Peripheral
The inter-integrated circuit (I2C) module provides an interface between a C64x+ DSP and other devices
compliant with Philips Semiconductors Inter-IC bus (I2C bus) specification version 2.1 and connected by
way of an I2C-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.
7.11.1 I2C Device-Specific Information
The C6474 device includes an I2C peripheral module (I2C). NOTE: when using the I2C module, ensure
there are external pullup resistors on the SDA and SCL pins.
The I2C modules on the C6474 may be used by the DSP to control local peripherals ICs (DACs, ADCs,
etc.) or may be used to communicate with other controllers in a system or to implement a user interface.
The I2C port supports:
• Compatible with Philips I2C 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- 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
Figure 7-24 is a block diagram of the I2C module.

The I2C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered
down.
A fast-mode I2C-bus device can be used in a standard-mode I2C-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.
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.
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.
Cb = total capacitance of one bus line, in pF. If mixed with HS-mode devices, faster fall-times are allowed.

• Full-duplex communication
• Double-buffered data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
• Direct interface to industry-standard codecs, analog interface chips (AICs), and other serially
connected analog-to-digital (A/D) and digital-to-analog (D/A) devices
• External shift clock or an internal, programmable frequency shift clock for data transfer
• SPI operation in master mode only
For more detailed information on the McBSP peripheral, see the TMS320C6474 DSP Multichannel
Buffered Serial Port (McBSP) Reference Guide (literature number SPRUG17).
7.12.1 McBSP Device-Specific Information
The CLKS signal for MCBSP0 and MCBSP1 can be sourced from an external pin or by PLL Controller 1.
For details, see Section 7.8. If the clock from the PLL Controller 1 is used, the clock is shared between the
two McBSPs.Figure 7-27 shows the sample rate generator clock (CLKSRG) selection logical diagram.

7.13 Ethernet MAC (EMAC)
The Ethernet Media Access Controller (EMAC) module provides an efficient interface between the C6474
DSP core processor and the networked community. The EMAC supports 1000BaseT (1000 Mbps) in
full-duplex mode, with hardware flow control and quality-of-service (QOS) support.
The EMAC module conforms to the IEEE 802.3-2002 standard, describing the “Carrier Sense Multiple
Access with Collision Detection (CSMA/CD) Access Method and Physical Layer” specifications. The IEEE
802.3 standard has also been adopted by ISO/IEC and re-designated as ISO/IEC 8802-3:2000(E).
Deviation from this standard, the EMAC module does not use the Transmit Coding Error signal MTXER.
Instead of driving the error pin when an underflow condition occurs on a transmitted frame, the EMAC will
intentionally generate an incorrect checksum by inverting the frame CRC, so that the transmitted frame
will be detected as an error by the network.
The EMAC control module is the main interface between the device core processor, the MDIO module,
and the EMAC module. The relationship between these three components is shown in Figure 7-34. The
EMAC control module contains the necessary components to allow the EMAC to make efficient use of
device memory, plus it controls device interrupts. The EMAC control module incorporates 8K-bytes of
internal RAM to hold EMAC buffer descriptors.
Figure 7-34. EMAC, MDIO, and EMAC Control Modules
For more detailed information on the EMAC/MDIO, see the TMS320C6474 DSP EMAC/MDIO Module
Reference Guide (literature number SPRUG08).
7.13.1 EMAC Device-Specific Information
The EMAC module on the device supports Serial Gigabit Media Independent Interface (SGMII). The
SGMII interface conforms to version 1.8 of the industry standard specification.

7.14 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 EMAC, retrieve the negotiation results, and configure required parameters in the EMAC
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.
The EMAC control module is the main interface between the device core processor, the MDIO module,
and the EMAC module. The relationship between these three components is shown in Figure 7-34.
For more detailed information on the EMAC/MDIO, see the TMS320C6474 DSP EMAC/MDIO Module
Reference Guide (literature number SPRUG08).

7.15 Timers
The timers can be used to: time events, count events, generate pulses, interrupt the CPU, and send
synchronization event so the EDMA3 channel controller.
7.15.1 Timers Device-Specific Information
The device has six general purpose timers: Timer0 to Timer5, each of which can be configured as a
general purpose timer or a watchdog timer. When configured as a general-purpose timer, each timer can
be programmed as a 64-bit timer or as two separate 32-bit timers.
Each timer is made up of two 32-bit counters: a high counter and a low counter. The timer pinout is
described in the next section.
7.15.1.1 Timer I/O Selection
Not all timer inputs and outputs are pinned out of the device. The six timers have a flexible (e.g. software
controlled) selection of timer inputs and outputs. At the chip level there are four timer pins, two input pins
(TIMI[1:0]) and two output pins (TIMO[1:0]). Each timer input can be configured to be driven by either of
the timer input pins, or by an FSYNC event (FSEVT[3:2]). Each output pin can be driven by any of the
timer outputs. This is programmable through software via the Timer Pin Manager Block, as shown in the
Figure 7-38. Not shown in the figure is the logic that gates the timer resets that are routed to the PLL
controller, shown in Figure 7-39.

7.15.1.2 Timer Watchdog Select
As mentioned previously, the timers can operate in watchdog mode. When in watchdog mode, the event
output from the timer can optionally reset the CPU. When used in this type of mode, Timer3, Timer4, and
Timer 5 correspond to C64x+ Megamodule Core 0, C64x+ Megamodule Core 1, and C64x+ Megamodule
Core 2, respectively. In order for the event not to trigger the reset when this operation is not desired, the
Timer watchdog reset selection register (WDRSTSEL) is created to turn this feature on/off. The
WDRSTSEL register is shown in Figure 7-41 and described in Table 7-67.

• Larger block sizes in shared processing mode
• Both max log MAP and log MAP decoding
• Sliding windows algorithm with variable reliability and prolog lengths
• The prolog reduction algorithm
• Execution of a minimum and maximum number of iterations
• The SNR stopping criteria algorithm
• The CRC stopping criteria algorithm
For more detailed information on the TCP2, see the TMS320C6474 DSP Turbo-Decoder Coprocessor 2
(TCP2) Reference Guide (literature number SPRUG21).

7.18 Serial RapidIO (SRIO) Port
The SRIO Port on the C6474 device is a high-performance, low pin-count interconnect aimed for
embedded markets. 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. The RapidIO
interconnect offers very low pin-count interfaces with scalable system bandwidth based on 10-Gigabit per
second (Gbps) bidirectional links.
The PHY part of the RIO consists of the physical layer and includes the input and output buffers (each
serial link consists of a differential pair), the 8-bit/10-bit encoder/decoder, the PLL clock recovery, and the
parallel-to-serial/serial-to-parallel converters.
The RapidIO interface should be designed to operate at a data rate up to 3.125 Gbps per differential pair.
7.18.1 SRIO Device-Specific Information
The approach to specifying interface timing for the SRIO Port is different than on other interfaces such as
McBSP. 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 SRIO Port, Texas Instruments (TI) provides a printed circuit board (PCB) solution showing two
DSPs connected via a 1x SRIO link directly to the user. TI has performed the simulation and system
characterization to ensure all SRIO interface timings in this solution are met. The complete SRIO system
solution is documented in the TMS320C6474 DSP SERDES Implementation Guidelines application report
(literature number SPRAAW9).
TI only supports designs that follow the board design guidelines outlined in the SPRAAW9
application report.
The Serial RapidIO peripheral is a master peripheral in the C6474 DSP. It conforms to the RapidIO™
Interconnect Specification, Part VI: Physical Layer 1x/4x LP-Serial Specification, Revision 1.2.

7.20 Emulation Features and Capability
7.20.1 Advanced Event Triggering (AET)
The C6474 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)

7.20.2 Trace
The C6474 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).

7.20.3 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 (Antenna Interface, RapidIO, 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, as per the specification. The JTAG interface uses 1.8-V buffers, compliant with the Power Supply
Voltage and Interface Standard for Nonterminated Digital Integrated Circuit Specification (EAI/JESD8-5).
7.20.3.1 IEEE 1149.1 JTAG Compatibility Statement
For maximum reliability, the C6474 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.

7.21 Semaphore
The device contains the Semaphore module for the management of shared resources of the DSP cores.
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 3 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.

7.22 Antenna Interface Subsystem
The Antenna Interface Subsystem (AIF) consists of the Antenna Interface module and two SERDES
macros. The AIF relies on the performance SerDes macro (high-speed serial link) with a logic layer for the
OBSAI RP3 and CPRI protocols. The AIF is used to connect to the backplane for transmission and
reception of antenna data, as well as to additional device peripherals.
The AIF supports OBSAI/CPRI daisy chaining between DSPs:
• OBSAI - 768Mbps, 1.536Gbps, 3.072Gbps link rates supported
• CPRI - 614.4Mbps, 1.2288Gbps, 2.4576Gbps link rates supported
OBSAI and CPRI standards compliant antenna interface
• 6 configurable (Full Duplex) high-speed serial links in either OBSAI or CPRI modes that can support a
variety of data rates:
• Supports star or daisy chain topologies.
• Each link can be used for uplink or downlink.
• Multiple slower links can be combined into faster speed links.
• Controls Word content supplied via DSP software.
The AIF is a slave peripheral, accepting all transactions from the DMA switch fabric, providing uplink data
to device memory and transmitting downlink, delayed stream, and PIC data from device memory. Each
link of the antenna interface includes a differential receive and transmit signal pair.

7.22.2 Antenna Electrical Data/Timing
The TMS320C6474 Hardware Design Guide application report (literature number SPRAAW7) specifies a
complete AIF interface solution for the C6474 device as well as a list of compatible AIF devices. TI has
performed the simulation and system characterization to ensure all AIF interface timings in this solution
are met; therefore, no electrical data/timing information is supplied here for this interface.
TI only supports designs that follow the board design guidelines outlined in the SPRAAW7
application report.

7.23 Frame Synchronization
Frame synchronization handles timing and time alignment on the device by coordinating timing between
the DSP cores. Up to 30 programmable events based on RP3 or system timer. One output is used for
exporting frame alignment to aid in synchronizing external components.
Frame synchronization assists with synchronization of clock inputs:
• OBSAI RP1 compliant input for frame burst data.
• UMTS frame synchronization boundary used as an alternative to RP1 for frame burst data.
• System timer synchronization used as an alternative to RP1.
The user may select between the OBSAI RP1-compliant FSYNCCLK(P|N) and FRAMEBURST(P|N)
signals or the alternate, single-ended ALTFSYNCCLK and ALTFSYNCPULSE inputs to drive the timers.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
