Sounds like a good job for an FPGA based solution. It's not nearly as
complex as you might think. Using an FPGA allows you to implement custom
peripherals can speed up your software algorithms, without the need of
additional CPUs. You can run hardware peripherals on the FPGA in parallel.
If you're interesting in this route I can provide some more pointers.
