board programmer DSP

Hello.

I hope that someone can help me.

Now I wanted to ask if they could move my question in the correct section, I apologize for the error.

Hi Marco

Welcome to the world of DSP.

I would start with a different processor. The ADSP-2184 is very old. You might look at one of the SHARC or Blackfin EZ Kits to get started. My preference is SHARC.

DSPs are not ideal for high speed sampling by themselves. Lets assume your core is running at 400 MHz. At 30 MHz sampling, you only have 400/30 = 13 instructions per sample to do things. Sometimes we mix FPGAs and DSPs for these kind of applications.

I think you might be able to use the ADSP-SC589 for an SDR if you dedicated one core to down sampling and the other for signal processing. The ARM would likely handle housekeeping. This is a very advanced processor for a newcomer. I would probably start with a ADSP-214xx instead and do something other than high speed (30 MHz) applications.

If you are interested in audio processing, we will have a low cost line of ADSP-21479 boards this fall. You might also look at sigmaDSP.
