That sounds like a good plan. I have used a similar approach a few times. A
microcontroller and an FPGA can give a huge amount of performance pretty
cheaply. There's nothing like parallel processing to speed things up and you
can do a lot of things simultaneously in an FPGA. Are you using VHDL for the
FPGA design?
