Abstract: A semiconductor device is provided. The semiconductor device includes a processing device that provides resource usage information including a utilization value; and a prediction information generating device that generates resource usage prediction information based on the resource usage information and provides the resource usage prediction information to the processing device. The prediction information generating device includes: an error calculator to calculate an error value between the utilization value and a predicted value included in the resource usage prediction information; a margin value calculator to receive the error value from the error calculator and calculate a margin value using the error value; an anchor value calculator to calculate an anchor value using the utilization value; and a predictor to output the predicted value using the anchor value and the margin value. The processing device controls resource allocation of the processing device based on the resource usage prediction information.

Abstract: A method of changing an operating frequency for performing a dynamic voltage and frequency scaling on a central processing unit included in a system on-chip is provided. A previous maximum peak workload of the central processing unit is detected in a history period of the dynamic voltage and frequency scaling when the operating frequency of the central processing unit is determined to be increased, and an increased operating frequency is applied to the central processing unit. The increased operating frequency is calculated based on the previous maximum peak workload of the central processing unit.
