[hpsdr] DFC

[Phil Harman]

Hi Scott,

Correct, it will also connect the PCIe bus directly to the DAC for transmit.

I believe Phil's efforts on DFC are wholly focused on his new circuit card design that I think he intends to present at Friedrichshafen this June, based on Teamspeak discussions. This card will take raw ADC output and put it directly onto a PCIE bus for processing in an NVIDIA GPU (CUDA processing) also resident on the same PCIE bus. The great advantage of this, of course, is that such an architecture would eliminate the requirement for complex and expensive FPGA processing, and thereby also open up development of what used to be FPGA firmware to C developers. 

73,

Scott/w-u-2-o

  I'm also curious about DFC, specifically, what will the minimum radio hardware requirements be?  I currently have an Atlas based system but seem to recall that, at least for the moment, this hardware will not support the new protocol and I think the new protocol is essential for DFC.  Should I be thinking of investing in a Hermes (or Hemes derivative) based radio in order to take advantage of DFC?
