ABSTRACT:
An arithmetic circuit includes an arithmetic circuit performing an arithmetic operation of a predetermined bit width in accordance with an arithmetic instruction, a holding circuit storing status information about the arithmetic operation by the arithmetic circuit and a logic circuit having a function of a logic operation. The logic circuit receives the status information stored in the holding circuit and the status information about a present result of arithmetic operation. The arithmetic circuit further includes a selector for selecting either the status information about the present result of arithmetic operation or a signal outputted form the logic circuit in accordance with a control signal based on the arithmetic instruction. The selector supplies the selected signal to the holding circuit.
