일단 3.3.5 에서 NEON 지원을 하는데 64비트 ARM일 경우에만 되는 듯?


FFTW 3.3.5 Jul 31, 2016

New SIMD support:

Power8 VSX instructions in single and double precision. To use, add --enable-vsx to configure.

Support for AVX2 (256-bit FMA instructions). To use, add --enable-avx2 to configure.

Experimental support for AVX512 and KCVI. (--enable-avx512, --enable-kcvi) This code is expected to work but the FFTW maintainers do not have hardware to test it.

Support for AVX128/FMA (for some AMD machines) (--enable-avx128-fma)

Double precision Neon SIMD for aarch64. This code is expected to work but the FFTW maintainers do not have hardware to test it.ft-with-fftw-library-c

AArch64 was introduced in ARMv8-A and is included in subsequent versions of ARMV8-A
