Is there a cheap way to get a high speed interconnect (as in more than USB2 or Ethernet) between a Digilent Atlys FPGA board and a Core i7 desktop PC? (If it matters, the PC runs Linux.) Going from the PC to the FPGA seems simple enough with the use of HDMI but what about the reverse? Would it be possible to use a USB 3 to SATA converter and then have the FPGA operate as a "SCSI generic device"?
Ideally, I would want nearly 3Gbps (the maximum data rate coming from the ADC) of usable bandwidth (meaning PCIe?), but I can make do with less. Also, whatever solution is proposed must allow the FPGA to be reprogrammed without having to reboot the PC in order to use it afterwards.
