  • Patent number: 9588578
    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.

  • Patent number: 9436253
    Abstract: System-on-a-chip (SOC) includes a dynamic voltage frequency scaling (DVFS) control unit; and a central processing unit (CPU) to operate the DVFS control unit. By using the DVFS control unit, a DVFS table may be selectively used according to any of various scenarios or modes of operation, thereby performing DVFS control.
