Abstract
A data processor has a general purpose register for storing arithmetic data and arithmetic results; an arithmetic device for MAC for performing a predetermined arithmetic operation by using the arithmetic data read from the general purpose register and outputting its arithmetic results to the general purpose register after a predetermined cycle; an arithmetic device for DIV for performing a predetermined arithmetic operation by using data read from the general purpose register and outputting its arithmetic results after a cycle longer than the predetermined cycle relative to the arithmetic device for MAC; and a temporary storing register for storing the arithmetic results outputted from the arithmetic device for DIV until the next arithmetic operation is terminated.
