Description: FFT算法实现
Radix2 可以计算 4，8，16，32, 64，128, 256....点FFT
Radix4 可以计算 4，16, 64, 256, 1024...点FFT
FFT_DIT_general.c 实现了 Radix2 和Radix4 的配合使用，可以计算Radix2可以计算的所有FFT，但效率比Radix2高。-FFT can be calculated Radix2 algorithm 4,8,16,32, 64,128, 256 .... can calculate the FFT Radix4 points 4,16, 64, 256, 1024-point FFT FFT_DIT_general.c ... Radix2 and Radix4 achieved with the use of Radix2 can calculate can calculate all the FFT, but Radix2 high efficiency.

Description: 一个用于ARM的基4/基5定点FFT算法，原作者是JDB，后来我扩展过16和256点的计算并用在项目中了，感觉速度还不错。现在重写了基于Linux GCC4的测试程序，可供使用者评估参考。建议安装FFTW3用来精确评估测试结果，相关范例已经在代码中了。-Radix 4/5 FFT routines supporting 16/64/256 and 20/80 calculations. The source originally contributed by JDB, I had extended 16 and 256 candidates and used it in our project it has been verified as fast and stable. Now we add some test vectors running on Linux with GCC 4 for testers who want to use or just evaluate it. Installing FFTW3 is recommended for evaluating the code exactly.
