FFTs Using AltiVec on Linux and Mac OS X

Posted by pudge on from the mmmm-fourier dept.

GregAllen writes "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."

  1. memory interleaving by ndevice · · Score: 2, Interesting

    from the article:
    "Split data seems to be much faster with SIMD architectures"

    caching associativity and memory interleaving anyone?
