I am working on the implementation of a highly-demanding signal processing algorithm, and I am not able to reach an acceptable execution time with vDSP's routines. I am now having a look at Metal and learn how to use it. It seems like Metal Performance Shaders as well as MPS Graph could replace almost all of my vDSP calls, but not the Fast Fourier Transform (which is the most time consuming part of the algorithm). I was wondering if there's a way for FFT methods to be included in MPS, because it could be insanely fast if optimized for unified architecture of the M1. Thanks !
