Compared to version 3.1.3 of FFTW, highlights of the FFTW 3.2 release

    (e.g. x86) with SIMD instruction.

  • Performance improvements for sizes with factors of 5 and 10.

  • Rewritten threading support for improved performance.

  • Support for the Cell processor, donated by IBM Research; see
    README.Cell and the Cell section of the manual.
