<div>>> 1) For example, is a 600MHz DSP faster than a 2GHz dual xeon ? I know DSP<br>>> has multi-level pipelines, MACs and Harvard bus... but anyone know if there<br>>> was a well coded (SMP) application using dual cores and reserving one entire<br>
>> core for DSP purposes to let us to compare performances ???<br><br>>The Zaptel echo canceller runs from the interrupt handler of the card's<br>>interrupts. You can easily control on which CPU this will occour..<br>
><br>>But I don't really see what you have to gain from this.</div>
<div> </div>
<div>
<div>Well, I`ve seen hardware cancelation boards using TI TMS320C55xx family for 60 channels 64ms... </div>
<div>I Think this DSP is slower than a single core of a dual core processor, so if I reserve 1 core only for echo cancelations, why my pc based system should be slower or worse than hardware based ?????</div>
<div> </div>
<div>I think this occurs because the code is not optimized ! So, instead of put everything in hardware, why not study the case better and optimize (even rewrite) the code ???</div>
<div> </div>
<div>Someone maybe already has studied the problem and could give me a good reason to believe that is not possible do it with a PC, but until now I am not convinced.</div>
