<p><P>PROBLEM TO BE SOLVED: To achieve power saving when a processing load on a GPU is large. <P>SOLUTION: A display driver 201 controls a GPU 116 operating at one of a plurality of operating frequencies. The display driver 201 includes a power consumption/total processing time acquisition unit 501 for acquiring power consumption per unit of time and a total processing time when the GPU 116 for each of the plurality of operating frequencies performs processing according to a processing request in response to the processing request from a processor to the GPU 116, a total power consumption calculation unit 502 for calculating the total power consumption for each operating frequency based on the power consumption per unit of time and the total processing time, and a GPU operating frequency control unit 503 for controlling the operating frequency of the GPU 116 based on the total power consumption for each operating frequency. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
