Ernst Mayer - Fortran 90 codes for Fast Fourier Transforms and Discrete Weighted Transforms, for use in number theory research.

Fast Fourier Transform code - By James Van Buskirk.

Jörgs Useful and Ugly FFT page - Code and links in Fortran and C for the Fast Fourier Transform.

Pipelined phase-rotation FFT - By David O'Halloran. The Welchel phase-rotation FFT is a new form of the fast Fourier transform (FFT) that replaces data movement at runtime with equivalent multiplications by precomputed constants. The result is an FFT that is easy to pipeline.
