Description: Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of complex samples. The intention of this article is to show an efficient and fast FFT algorithm that can easily be modified according to the needs of the user. I ve studied the FFT algorithm when I was developing a software to make frequency analysis on a sample of captured sound.-Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of co mplex samples.

Description: 一个非常高效的基于TS101的8点fft代码,该代码实现8点复数FFT,入口数据按实部,虚部交替存放 FFT结果也按实部,虚部交替存放.
程序没有任何循环,也无须循转因子.
非常高效啊-a very efficient on the TS101 8:00 fft code that realization 8:00 complex FFT, import data by the real part and imaginary part of the turn kept FFT results by the real part, the imaginary part of the turn of storage. No recycling process, they will not need to turn on factor. very efficient ah!
