Digital signal processors for communications, video infrastructure, and audio

This paper provides a description of the features of Texas Instruments' new TMS320C6455 and TMS320C672x series digital-signal processors (DSPs). The high-speed Serial RapidIOtrade port, DDR2 memory controller, and multiple standard ports of TMS320C6455 DSPs make these processors ideal for communications and video infrastructure systems. Similarly, the audio-oriented peripherals and large amount of on-chip memory included on the floating-point TMS320C672x series DSPs enable professional audio applications. Both processors include enhanced CPUs with instruction set enhancements focused on algorithms specific to their application space and a flexible DMA architecture suited to their system needs
