Abstract

Execution of machine instructions in a microprogrammed processor is effected by several byte field operands within a microprogramme loop held in a memory. The main memory has a work store and a microprogramme store. Addressing of microprogramme locations is affected over a buffer or ROM within the control unit. Microinstructions are acc eased into a register. Two scratch pad registers within the processor operate in association with work space registers. The instruction format for bye organised microinstructions has a bit group to locate the microprogramme loop in memory, a bit to locate the main function, two address field group and three test fields.
