need micro-controllers that operate at about 900 Mcyc to do the work.
AFAIK, there are no commercially microprocessors of any sort that are
rated for operation above 700 MHz.
If you're thinking of 8-bit microcontrollers, one of the fastest is the
Scenix SX. It is currently available rated for 50 MHz operations, for
a 20 ns instruction cycle. Not bad for under $5.
