FFTW DSP Libraries

The NAS FFTW library is an optimised implementation of the well-known FFTW library (see http://www.fftw.org for details).

We provide highly optimised FFTW libraries for:

• ARM A53, A57 and A72
• PPC T2080
• PPC T2081
• PPC T4240
• Intel AVX512
• Intel Phi
• Intel AVX2
• Intel AVX
• Intel SSE

Full reference manuals for Single-Precision (FFTWF) and Double-Precision (FFTW) can be found below:

• FFTWF Single-Precision DSP Library Manual.
• FFTW Double-Precision DSP Library Manual.
