DEVICE FOR DECODING AN OPERATION CODE AND PROVIDING A PLURALITY OF SEQUENTIAL OUTPUT STATES

摘要

A multi-bit operation code (22) is decoded into a single product term in the AND array (20) of a programmable logic array. That single product term is then processed through a clock (45) driven sequencer (32) to generate a plurality of sequential product term signals. These sequential product terms are decoded by the OR array (30) of the programmable logic array to generate a plurality of sequential time states (58) corresponding to the decoded operation code (22).
