Sounds like you're up and running OK. Note that another nice aspect of the built-in self-test sets in the current (and future) code is that it makes it a lot easier to do run-time profiling of the binary. Just build a version with all your usual compiler flags and also with -xcollect, then run one or more of the self-test sets, then incorporate the RTP data that were collected by doing a final build with -xuse replacing -xcollect. I believe Bill Rea got a nice (10-20%) speedup at most FFT lengths this way. Note that the optimal FFT radix sets may change once profiling has been done.

Happy Hunting,
