Abstract
In one embodiment, a system includes power management control that controls a duty cycle of a processor to manage power. The duty cycle may be the amount of time that the processor is powered on as a percentage of the total time. By frequently powering up and powering down the processor during a period of time, the power consumption of the processor may be controlled while providing the perception that the processor is continuously available. For example, the processor may be a graphics processing unit (GPU), and the period of time over which the duty cycle is managed may be a frame to be displayed on the display screen viewed by a user of the system.
