Strange as it sounds, those results actually look better. I'm not sure
about the divide by zero case for the fft_filters, but the other
results you have are very close to what they should be. It almost
looks like there is an off-by-1 indexing problem. Either that or your
ALU is messed up. But there's something strange about the numbers
you're showing. And you haven't changed any files in the source code
(that is, 'git status' shows nothing)?
