Abstract: A method of Dynamic Voltage Frequency Scaling (DVFS) of a processor includes measuring a first utilization of the processor utilized to execute at least one of a graphic task and a computing task. A second utilization is generated by adjusting the first utilization based on a duration of the graphic task and a duration of the computing task. An operation frequency of the processor is determined based on a comparison of the second utilization with at least one threshold value.

Abstract: A processor and a semiconductor device including the same are provided. The processor includes an operation unit, an operation counter which measures a first operation pattern by counting first operations of the operation unit and measures a second operation pattern by counting second operations of the operation unit which are different from the first operations, a power measurement unit which calculates power consumption of the operation unit using a first weight for the first operation pattern and a second weight for the second operation pattern, and a frequency controller which adjusts an operating frequency used for the first or second operations by using the calculated power consumption.
