摘要
在电子设备中数字信号处理技术越来越多地得到应用,而FFT运算是数字信号处理技术的基石,FFT运算主要由DSP来完成,DSP的FFT运算程序的编写是一项重要工作,但FFT算法程序的编写调试费时费力。TI公司提供了以TMS320C54x系列芯片为基础的DSPLIB库函数,包含FFT运算,使在TMS320C54x系列芯片上进行FFT运算变得容易,本文就DSPLIB函数库进行介绍并就使用方法进行详细说明。
There are more and more applications of digital signal process technology in electronic equipments. Most of digital signal process applications are based on FFT which is realized by DSP. The programming of FFT routine is a important work, and a hard work. Texas Instruments Inc has provide a DSP library on C54X DSP which make the realization of FFT on C54X DSP easy. This paper describes the DSP library and shows how to use it.
