PURPOSE: The data operational processor of MPU(Micro Processor Unit) is provided to improve the performance of a data processor by a user directly making a control signal of data operator within served resources. CONSTITUTION: The data operational processor(300) comprises a data operation execution part(303), multiplexer(302), and decoder(301). The data operation execution part processes the data operation. The multiplexer delivers a control signal to the data operation execution part. The decoder delivers the control signal responding to the multiplexer by decoding and checking instruction set received from a system. A user-defined control register(304) of MPU has the control signal information of user definition.
