Overview
The TMS320C32PCM60 is a digital signal processor (DSP) from Texas Instruments, part of the TMS320C3x generation. This enhanced 32-bit floating-point processor is manufactured using 0.7-µm triple-level-metal CMOS technology. It offers significant improvements over its predecessors, including a variable-width external-memory interface, faster instruction cycle time, power-down modes, and a two-channel DMA coprocessor with configurable priorities. The processor is designed for high-performance applications and is compatible with object code from the TMS320C30 and TMS320C31 processors.
