Cast C32025
The C32025 is a 16-bit fixed-point digital signal processor core. It combines 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.GENERAL DESCRIPTION
Developed for easy reuse with ASICs or FPGAs, the core requires under 18000 ASIC gates.APPLICATIONS
