Abstract

A microprocessor with an improved register part is disclosed. The register part includes a plurality of registers for holding data and adding circuits connected to the outputs of predetermined two registers. Adding circuits are provided as a preceding operation circuit and a part of the operation to be executed in an ALU or a multiplier is carried out in the preceding operation circuit. At the time two data to be used in an operation are applied to the predetermined two registers, addition is started in the preceding operation circuit. Therefore, the number of instructions required for carrying out the operation is reduced thereby realizing faster processing.
