To get a PIC to execute 1 instruction per nanosecond you would have to clock the device at 4GHz, which is a little on the high side. Perhaps a Scenix chip instead? (just kidding!)

If not possible with Pics are there any other microcontrollers that can execute instructions this fast? Thanx in advance for for responding. Dominic
