[FREESW]FFTW Home Page  
FFTW is a C subroutine library for computing the Discrete Fourier Transform (DFT) in one or more dimensions, of both real and complex data, and of arbitrary input size. We believe that FFTW, which is free software, should become the FFT library of choice for most applications. Our benchmarks, performed on on a variety of platforms, show that FFTW's performance is typically superior to that of other publicly available FFT software. Moreover, FFTW's performance is portable: the program will perform well on most architectures without modification.

The benchFFT Home Page  
benchFFT is program to benchmark FFT software, developed by Matteo Frigo and Steven G. Johnson at MIT. The benchmark incorporates a large number of publicly-available FFT implementations, both in C and in Fortran, and measures their performance and accuracy over a wide range of transform sizes. It benchmarks both real and complex transforms in one, two, and three dimensions.
