Hi all, I'm strugling making the right choice for our new board. I Need something like 2 GFLOPS in order to process audio. Audio is sampled with 44Ks/s externally and internally at 10xFS. I have been aiming at the ADSP-21161 or ADSP-21261 as a target. I know there are 2 ways of processing; Parallel and serial. I have no clue how to create a parallel system ( bus arbiter, software ).

We have a system with a backplane with five slots for ADSP-21065L DSP's based custom cards. Each DSP card has SPORT 0 DR0A and DT0A tied together. TCLK0, RFS0, and the common DT signals are then each run through a 33ohm series to the backplane bus. The problem is that we are having significant noise problems. One slot in our back plane seems to have problems on the TCLK line as the audio...

We have implemented a reed solomon encoder (238,255) followed by an interleaver (depth of 3 blocks of 255) .Over this we perform convolutional encoding. The codes are running on the adsp 219x processor. The incoming clock rate is at 2.048 Mbps and outgoing bits are pushed out at a clock rate which is basically 2.048*255/238 *8/7 = 2.5078 Mbps .
