The problem is that MP3 decoding takes a lot of computes, more than a simple PIC can reasonably do in real time. Serial algorithms also lend themselves well to hardware implementation because you can set up a pipeline. Each block in the pipeline is working o= n successive data, but they are all working simultaneously, something a singl= e CPU can't do. A pipeline increases latency, but in the case of decoding a MP3 stream a small delay is of no consequence as long as the overall rate can be sustained. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
