Description: 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.
