PROBLEM TO BE SOLVED: To provide an information processor capable of reducing unnecessary power consumption by setting the operation frequency and operation voltage of a processor to appropriate one in the case of executing service processing.SOLUTION: An information processor includes: a processor; a storage part; an operating system; and an operation frequency/operation voltage control part. The storage part stores an operation frequency and operation voltage predetermined for each of a plurality of service processing operating in a privilege mode. When any of the plurality of service processing is called, the operating system reads the operation frequency and operation voltage corresponding to the called service processing from the storage part. The operation frequency/operation voltage control part changes the operation frequency and operation voltage of the processor to the operation frequency and operation voltage corresponding to the called service processing, which is read by the operating system. |
