PROBLEM TO BE SOLVED: To expect technique for saving power consumption since power consumption shows tendency to increase as multi-functioning is promoted in a portable terminal. SOLUTION: A data processor 10 is the one for outputting a prescribed arithmetic result to input data and constituted of an arithmetic processing part 30 for performing a general-purpose arithmetic processing concerning optional input data, an exclusive processing part 40 consisting of gates which are smaller in number than the gates which are comprised in the arithmetic processing part so as to perform a processing concerning specified input data and a data judging part 20 for judging whether input data is the specified one or not. When input data is the specified input data, the exclusive processing part processes input data and outputs the processing result as an arithmetic result. When input data is the one except the specified input data, input data is processed through the use of the arithmetic processing part and the processing result is outputted as the arithmetic result. |
