[hpsdr] Ozy with Gb Ethernet

[Eric Ellison]

Looks like Gig it is. You got your job cut out for you! (as they say in
"Mission Impossible"). Can we manage to stay away from BGA's for the Bare
Board folks? Although Lyle is set up to go on them!

 

Good Luck, All you need is a name for the project! You have already earned
it from all our abuse! Mercury is already taken!

 

Thanks

Eric

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!
