Hi Berkdan, Failing to understand why you need what you think you need...
IMO a better setup would be a PC with a mesanet PCI card. This is in fact a FPGA. Perhaps you could do a thing like you propose, but i think this is a setup involving a lot of components where i fail to see the merit. What does the machine need to do, why do you need a 500 kHz step rate? I wonder which driver/motor would be able to handle that. You can run Machinekit directly on a raspberry pi, or a beaglebone for that matter.
