I will attach a USB audio interface for testing purposes and if the
performance is sufficient for me, i'll look into attaching an audio codec to
its ISP bus.
BTW: i don't need jack to run.. I'm not even sure it can run at all on that
board. All i need will be a single application which will feed audio into
LADSPA plugins.. Jack would be overkill..
For the sake of sanity, here is the manual for the chip in question.
Note that the floating point co-processor has no divider but on the
other hand has a fast Integer Multply Accumulate with four 72bit
accumulators. Kind of hellish to make sense out of in a standard C
environmenet, but not at all bad for sound processing. Look for chapter
two (pdf page 35):
