Hallo,
I have an audio datastream and want to process this on the dsp. I tried to use dsplink with RingIO to get the data from the arm to the dsp-core but the performance is very poor. Then I tried the readwrite example with proc_write and there is also such a poor performance.
Actually it's faster to process the datastream on the arm-core but there are many operations which should calculate faster on the dsp.
time for the same datastream (i think it was a 3MB datastream):
arm: 70µs
dsp with ringio: 271µs
Is there any way to get faster communication bitween arm and dsp?
