Benchmarks for open-source AltiVec FFTs

AltiVec is a set of instructions for the PowerPC processor which enhance the performance of signal and image processing using a SIMD (single-instruction multiple-data) approach. After searching for a good open-source AltiVec implementation of the Fast Fourier Transform (FFT), I have put together the AltiVec FFT page. It has all of the source, some benchmarks, and runs on Mac OS X or LinuxPPC. I even compared it to the venerable (but scalar) FFTW.
