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

A computing system, comprising:

• a processor comprising at least one processor core;
• a power management circuit configured to provide a clock signal and a voltage for an operation of the processor;
• and
• a memory storing a dynamic voltage and frequency scaling (DVFS) computer program,
• wherein the processor is configured to execute the DVFS computer program to:
• set a plurality of power levels corresponding to a plurality of available frequencies of the clock signal for the operation of the processor;
• set a plurality of power steps corresponding to the plurality of available frequencies;
• and
• control a conversion between the plurality of power levels based on a utilization of the processor and the plurality of power steps.

A method of performing dynamic voltage and frequency scaling (DVFS), the method comprising:

• setting a plurality of power levels corresponding to a plurality of available frequencies of a clock signal for an operation of a processor;
• setting a plurality of power steps corresponding to the plurality of available frequencies based on at least one of an operation temperature of the processor and an available power of the processor;
• determining a power target frequency based on a current utilization of the processor and a current power step corresponding to a current power level determined from among the plurality of power levels;
• and
• determining a next power level from among the plurality of power levels based on the power target frequency.
