Hi Frank, LibAV and FFTW both have support for NEON extensions. It would be interesting to benchmark their FFT against what we're using now. That could be a quick validation regarding whether NEON is helpful. Both the softmodem and the codec can use accelleration. One concern of ours is the low end. We are looking at STM32F4 and Sitara for embedding in radios. I think we're limited to conventional floating point on those. Thanks Bruce |
