Perhaps...
It's much better suited to a CPLD or FPGA though. Although a uC could be
used for postprocessing. True, the Parallax chips are pretty powerful, but
I'm not convinced it's the right tool for the job.

Can't ask for better than that. Although I have been considering farming
out the lower level processing to a uC. Problem is in doing this a lot of
flexibility is lost.
