專案描述

FFTW is a fast C FFT library. It includes complex, real, symmetric, multidimensional, and parallel transforms, and can handle arbitrary array sizes efficiently.It is typically faster than other freely available FFT implementations, and is even competitive with vendor-tuned libraries (benchmarks are available at the homepage). To achieve this performance, it uses novel code generation and runtime self optimization techniques (along with many other tricks).

3.2

Real-to-complex transforms, non-power-of-two
transforms, and multi-threaded transforms were
made faster. Cell processor support was added.
MIPS paired-single SIMD support was added.

3.1.3

This release fixes a bug that causes incorrect
results to be computed in programs that use both
REDFT11 (a.k.a. DCT-IV) and RODFT11 (a.k.a.
DST-IV) at the same time.

3.2-alpha2

Support for the Cell processor was added along with a 64-bit API, experimental MPI support, and support for MIPS paired-single SIMD instructions. r2c transforms and multi-threading were accelerated. A return value bug in the Fortran interface for dfftw_init_threads was fixed. G77 wrappers are now optional if gfortran is detected.
