Abstract
A method for reducing power consumption of a processor is disclosed comprising steps of applying time-frequency transformation to a plurality of load values of the processor to obtain the feature sampling cycle of the processor, and adjusting the voltage/frequency of the processor based on said feature sampling cycle. With the method of the present invention, the processor load value in next time interval can be accurately predicted, and thus the voltage/frequency of the processor in the next time interval can be adjusted on the basis of the load value.
