Hi all:

Looking for a solution to implement DVB-s2 LDPC at 8-9 gbs or 
above.
1) anyone know of a silicon solution for this rate?
2) what is the feasibility of achieving this rate with
	a) Tilera jumpgen
          b) Nividia GPU's
   how expensive, number of processors, etc

I doubt one exists.   DVB-S or S2 does not support rates anywhere
close to 8 Gbps.   Very few comm links do other than fiber, and fiber
doesn't need that much error correction.

It's possible, but you may have to have a lot of those running in
parallel and latency might be high.

Nvidia's Tesla system has 448 of the CUDA engines running in parallel.  It
is, in fact, a teraflop processor.  How one would go about implementing a
massively parallel LDPC decoder is beyond my knowledge, however.
