[casper] FFT speed optimizations

2016-09-21 Thread Guenter Knittel
Hi all, I'm still busy trying to speed-optimize our DSP pipeline, and it's amazing how sophisticated the tools are in picking ever new signals to let them miss timing. But a few of them occur frequently, often inside fft_wideband_real, and so I'm hoping that somebody can give me a hint.
