VoIP & FPGA

Hi guys,

Just a dummy level question. Is it possible to implement a VoIP solution with the Xilinx SP3 kit? If not is there a better FPGA solution for it? Thanks!

Howdy Leo,

Not knowing what you consider a "solution" to be, it's difficult to answer your question. Stuff like if it needs to be a real-time demo, the number of VoIP channels, where the audio will come from and go to, etc.

The Xilinx S3 kit doesn't seem to have A/D or D/A converters, so you'd have to do that elsewhere (your computer?). Amazingly, even in this Internet age, it also doesn't look like it has an Ethernet phy, which in my mind, would mostly rule it out for your application if your intent is real-time. There are plenty of other FPGA demo boards (from third parties) which have both A/D, D/A, and Ethernet ports. Might not be quite as inexpensive, but shouldn't break the bank either.

Once you figure out how to get the voice in and out of the FPGA, the actual VoIP encoding should be a piece of cake to do in *any* FPGA. Well, I suppose it could vary from a piece of bunt cake to a whole wedding cake, depending on which encoding standard(s) you want to support and your experience with them.

Have fun,

Marc

Thanks Marc. I was thinking about getting into the VoIP development & I need a kit that I could start playing with. Then I saw the S3 Kit and was woundering if is something useful for this project. I guess its not! I really appericiate your help. Thanks again!
