Abstract
A data-processing device has a clock generator for generating pulse signals .phi.1 and .phi.2, an ALU capable of executing various arithmetic-logic operations during cycles corresponding to the pulse signals .phi.1 and .phi.2,and a control unit for generating a control signal which causes the ALU to execute an arithmetic-logic operation according to an instruction. This data-processing device further includes a transfer switch for causing the ALU to execute an arithmetic-logic operation, which is for generating output data equal to input data, during a cycle in which the ALU would otherwise be idle.
