Abstract
In microcomputers and digital signal processors in which a central processing unit for controlling the entire system and a digital signal processing unit having a product sum function required to process digital signals efficiently are mounted on one and the same chip, an increase in the number of processing steps caused by differing types of data handled by the calculators is prevented, thereby enhancing the efficiency of the digital signal processing.
