Overview
The TMS320C6472ECTZ7 is a high-performance fixed-point digital signal processor (DSP) developed by Texas Instruments. This device is part of the TMS320C6000™ DSP platform and is designed to meet the demands of high-end industrial, mission-critical, image and video processing, communication, media gateways, and remote access servers. The TMS320C6472 features six optimized TMS320C64x+™ megamodules, each providing high performance with low power dissipation. The device is available in three different speeds: 500 MHz, 625 MHz, and 700 MHz.
The TMS320C6472 is built on the third-generation VelociTI™ very-long-instruction-word (VLIW) architecture, which enhances its capability for complex signal processing tasks. It includes large on-chip memories, with 768K-Byte of shared RAM and 608K-Byte local L2 RAM per C64x+ megamodule, reducing the need for external memory and optimizing system power and cost.
