Looking for signal processing library or examples using the SPE instructions.

I am looking for information about using the SPE (Signal Processing Extensions) instructions in

a P1022 processor.  The compiler (gcc) in Qoriq Yocto 1.6 seems capable of generating the

instructions, and they do work, but beyond the SPEPIM reference manual I haven't been able

to find much other support.  Are there libraries available?  We are mostly interested in audio

processing, i.e. seeing if we can handle some of the tasks currently done by dedicated DSP

chips.

 

Has anyone had much luck doing this?

 

Thanks in Advance
