Please help about literature!

Good day to all!

Maybe my question is not supposed to be on this forum, but i would be very thankfull if smb helped me. So, i need some lierature about "speech compression using FPGA" or "speech processing on FPGA". Has smb any links, related to this problem? or maybe smb knows some good books, dedicated my question?

 

Thanks!

Hi,

 

Have you done any of your own research?

http://scholar.google.co.uk/scholar?q=fpga+speech+processing&hl=en&num=30&um=1&ie=UTF-8&oi=scholart

 

Has quite a lot of hits.

 

However - you are probably approaching this the wrong way.

 

If you want to do speech processing - first figure out what you want to do, then figure out an algorithm for it, and prototype it in software (C, Matlab, Scilab, something high-level).

Then (and only then) you *might* want to think about FPGAs.  If you can perform the task you want in a processor, it's a lot easier to develop and deploy that way.   If you absolutely need and FPGA for performance reasons, then you start down the road of converting your sw to FPGA (either using tools like AccelDSP, CatapultC or ImpulseC (for example)), or you build it up in VHDL from scratch, comparing results to your software efforts as you go.  This is not a small task whichever way you do it (even if you are a guru at the speech processing part) - you might want to get help!


Cheers,
Martin
