    Abstract: A microprogram control subsystem discloses two control stores, one of which is accessed and utilized only on the first cycle of a microprogram sequence utilized to execute an information handling system instruction. A portion of the operation code of the system instruction is used to address the first-cycle control store to provide access to a microinstruction having fewer binary bits than normal microinstructions, and is effective to direct access to the remainder of the microprogram sequence contained in the other control store.
