[hpsdr] Ozy with Gb Ethernet

[Phil Harman]

HI Warren,

Welcome to the group. Not sure what we would gain my going to T-100 Ethernet since at  the moment we can get 35-40MB/s over USB2.  The uWSDR guys have chosen Ethernet as their means of communicating with their hardware mainly so they can mount it at the top of a tower and run CAT5 cable to it I think, see

I think an Ozy type board with GB Ethernet would be just great since we could transfer some of the DSP work to the PC and look at MHz of bandwidth at a time.

  Wow! Some good information to start looking at, thanks gang!

  Eric, I looked at tha Master's Thesis, and found the PCI interface interesting.  I just finished designing a PCI 64/66 interface in a Xilinx XC2V3000, with 9 DMA engines for the Initiator and a Target interface. The Xilinx PCI IP core license is $10K by itself. 

  Keep the ideas coming!
