METHOD OF POWER MANAGEMENT FOR GRAPHIC PROCESSING UNIT AND SYSTEM THEREOF

摘要

A power management system to manage power of a graphic processing unit is disclosed. The power management system includes: a dynamic voltage and frequency scaling (DVFS) driver which includes an interface which calls a device driver of the graphic processing unit or is called by the device driver, and controls an operating voltage or an operating frequency of the graphic processing unit; and a DVFS governor interface module which provides a power management policy module of an operating system with an interface for the DVFS driver. Therefore, the power management system according to the present invention can apply, to the graphic processing unit, a power management policy of the operating system based on changes in the workload of the graphic processing unit, independently of a hardware configuration of the graphic processing unit.
