C32025 Overview
The C32025 is a 16-bit fixed-point digital signal processor core. It bines the flexibility of a high-speed controller with the numerical capability of an array processor. The C32025 has the same instruction set as the TMS320C25 and also provides the same interrupts, serial interface and timer.
