Abstract
PURPOSE: To make an operation speed high by executing multiplication or division dependently upon addition between contents of an integral multiple register and an operation result register or subtraction between contents of an operation register and the integral multiple register.
CONSTITUTION: Operation register X stores one of a multiplier and a multiplicand or a divisor, and integral multiple register Y stores the other of the multiplier and the multiplicand or numerics once, twice, four times and eight times as large as the divisor. Operation result register Z and store the product, the quotient, or their intermediate result. That is, multiplication and division are executed dependently upon addition 30 between contents of register Y and register Z and subtraction between contents of register X and register Y by control part 33 including a prescribed program. As a result, the operation speed can be made high.
