Abstract
PURPOSE: To make operation high-speed to improve the operation function of an information processing unit by designating addresses from two directions by a general register and reading two data at a time.
CONSTITUTION: Instruction register IR21 stores instruction words, and general register 27 can designate addresses from two directions, namely, the A port side and the B port side to read two data at a time. Then, two data read from register 27 are selected on a basis of information of a field designating a source register of the micro instrcution word by general selector switches 30 and 31 and are inputted to operation circuit 32. As a result, operation can be made high-speed to improve the operation function of the information processing unit.
