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
