Method of performing dynamic voltage and frequency scaling based on power step

摘要

The method of performing Dynamic Voltage Frequency Scaling (DVFS) includes: setting a plurality of power levels corresponding to a plurality of available frequencies of an operating clock signal for operation of a processor, each of the plurality of available frequencies Setting a corresponding plurality of power steps and controlling the switching between the plurality of power levels based on the plurality of power steps and the utilization of the processor. By efficiently switching the power level based on the power step, it is possible to efficiently control the performance and power consumption of the processor.
