Yes, I'd be interested.

I haven't profiled on ARM specifically recently, but it tends to always
be the usual suspects: filter_mem16(), pitch_xcorr(), iir_mem16(), and a
few others. If you ever want to optimise filter_mem16() or iir_mem16(),
let me know because the best way to start may not be the C function.
