Microprocessor for bit strings operations.

摘要

A microprocessor includes a barrel shifter, a rewrite section, and a control section. The barrel shifter serves as a shift unit which is controlled by a microprogram and operated by microinstructions for performing extraction, insertion, and comparison of consecutive bit strings in word data. The rewrite section directly rewrites output data from the barrel shifter into its an input. The control section controls the rewrite section by using the microprogram. <IMAGE>
