Abstract:
1. A computer, comprising: a processor that processes specific operation data, the specific operation data including a plurality of portion data, the processor processing the plurality of portion data one by one; a data length detector that obtains a data length of a portion of the specific operation data; and a power controller that controls a power consumption of the processor on the basis of the data length obtained by the data length detector, the power control being performed while the processor processes the specific operation data, the power controller controlling a clock frequency of the processor to reduce the power consumption of the processor, the power controller determining the clock frequency on the basis of a sum of (1) a first product of a first coefficient and the data length of a portion data of the first specific data and (2) a second product of a second coefficient and the data length of a portion data of the second specific data.
