The SM320C6472 device is a Texas Instruments next-generation fixed-point digital signal processor (DSP) targeting high-performance computing applications, including high-end industrial, mission-critical, high-end image and video, communication, media gateways, and remote access servers. This device was designed with these applications in mind. A common key requirement of these applications is the availability of large on-chip memories to handle vast amounts of data during processing. With 768K-Byte of shared RAM and 608K-Byte local L2 RAM per C64x+ Megamodule, the SM320C6472 device can eliminate the need for external memory, thereby reducing system power dissipation and system cost and optimizing board density.

The SM320C6472 device has six optimized TMS320C64x+™ megamodules, which combine high performance with the lowest power dissipation per port. The TMS320C6472 device includes three different speeds: 500 MHz, 625 MHz, and 700 MHz. The C64x+ megamodules are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The C64x+ megamodule is based on the third-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making devices like SM320C6472 an excellent choice for applications including video and telecom infrastructure, imaging/medical, and wireless infrastructure (WI). The C64x+™ devices are upward code-compatible from previous devices that are part of the C6000™ DSP platform.

The C64x+ megamodule core employs eight functional units, two register files, and two data paths. Like the earlier C6000 devices, two of these eight functional units are multipliers or .M units. Each C64x+ megamodule core .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 a 500-MHz clock rate, this means 4000 16-bit MMACs can occur every second. Moreover, each multiplier on the C64x+ megamodule core can compute one 32-bit x 32-bit MAC or four 8-bit x 8-bit MACs every clock cycle.

The C64x+ megamodule integrates a large amount of on-chip memory organized as a two-level memory system. The level-1 (L1) program and data memories on this C64x+ megamodule are 32KB 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 2 (L2) memory is shared between program and data space and is 608K-Byte in size. L2 memory can also be configured as mapped RAM, cache, or some combination of the two. The C64x+ megamodule also has a 32-bit peripheral configuration (CFG) port, an internal DMA (IDMA) controller, a system component with reset/boot control, interrupt/exception control, a power-down control, and a free-running 32-bit timer for time stamp.

The peripheral set includes: three Telecom Serial Interface Port (TSIPs); an 16/8 bit Universal Test and Operations PHY Interface for Asynchronous Transfer Mode (ATM) Slave [UTOPIA Slave] port; two 10/100/1000 Ethernet media access controllers (EMACs), which provide an efficient interface between the C6472 DSP core processor and the network; a management data input/output (MDIO) module (shared by both EMACs) that continuously polls all 32 MDIO addresses in order to enumerate all PHY devices in the system; a Serial RapidIO® with two 1x lanes and support for packet forwarding; a 32-bit DDR2 SDRAM interface; 12 64-bit general-purpose timers; an inter-integrated circuit bus module (I2C); 16 general-purpose input/output ports (GPIO) with programmable interrupt/event generation modes; and a 16-bit multiplexed host-port interface (HPI16).

The C6472 device has a complete set of development tools which includes: a C compiler, an assembly optimizer to simplify programming and scheduling, and a Windows® debugger interface for visibility into source code execution.
