As another naive note, since sincosf seems to be the dominating function by a large factor, this website might be worth a read:
http://www.devmaster.net/forums/showthread.php?t=5784 I know there is a fast sine and cosine somewhere for filtering, but I also thought those caused some issues recently with GMSK demodulation? When converted from floating -> fixed point for transmission, the error might be swamped by the quantization noise? The last section of the forum post really is interesting since we generally do work on more than 1 piece of data at a time, the SIMD version of calculating sines or cosines might come in handy.
