一种基于CCS与DSPs串口实现FFT的方法

The Realization of FFT Based on UART and CCS

FFT是对实时采集的动态数据进行频域分析、处理的基本算法,本文针对DSP系统特点设计了一种高效的FFT的实现方法,以完成对动态信号的实时分析、处理。使用串口将DSP评估板与PC机相连,利用CCS作为开发平台来进行调试,分析了调试过程中遇到的问题给出了解决的方法,并利用MATLAB验证了该方法的正确性与可行性。

FFF is the fundamental algorithm of frequency-domain analysis and processing of the real-time dynamic data acquisition. Directing at DSP system＇s characteristic, the present paper designs an efficient realization of FFF in order to realize real-time analysis and processing of dynamic signal. Through connecting DSP evaluation board with PC by UART and debugging them based on CCS, this paper analyzes the problems happened in the process of debugging and provides the solution to these problems,and use MATLAB to prove the correctness and feasibility of the method.
