Technical Paper / Application Report

More InfoLess Info

The TMS320C6455 fixed-point digital signal processor (DSP) and the TMS320C6474 communications infrastructure DSP are two of Texas Instruments' high-performance DSP processors, each offering high-speed DSP processing, large internal memories, a rich set of peripherals, and other support functions useful in a system environment.

This application report describes device considerations for migrating a design based on the TMS320C6455 to one based on the TI TMS320C6474. These two devices have many similarities; they both contain the TMS320C64x+ DSP central processing unit (CPU) core, and feature a similar mixture of memory and other peripherals. This document describes the details of the considerations of concern for performing this migration.

Note that since this document describes migration from a TMS320C6455 device to a TMS320C6474, familiarity with the TMS320C6455 device and its documentation is assumed.
