WebThe performance depends strongly on the SIMD instructions that are used. muFFT has four versions: no-SIMD, SSE, SSE3 and AVX. pffft also has four variants: no-SIMD, SSE, AltiVec and NEON. These libraries don't have all the features of FFTW and MKL. muFFT supports only sizes 2^N, pffft supports radices 2, 3 and 5. WebFFTW can also take advantage of certain hardware-specific features, such as cycle counters and SIMD instructions, but this is optional. Question 2.2. Does FFTW run on Windows? …
