一种可编程FFT处理器

A Programmable FFT Processor

本文介绍了一种用TMS320C25实现的可编程FFT 处理器的硬、软件设计思想.这种FFT 处理器很好地利用了TMS320C25芯片的硬、软件特点,构成简单,编程灵活,可在2ms 内完成128个复数点的FFT 运算.

This paper gives the design considera-tions of a programmable FFT processor onhardware and software on the base of TMS320C25,this processor takes advantage of TMS320C25's characteristics,it is easy to buildand Program.With this processor,A 128Complex-Point FFT can oe finished in 2ms.
