In one embodiment, a system includes a power management controller that controls a duty cycle of a processor to manage power. 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. Additionally, in some cases, it may be a better power/performance tradeoff to run the processor at a higher power/performance state if the processor is executing for a significant portion of the execution interval (e.g. the frame time for a GPU). Executing at a higher power/performance state may permit a realization of a greater number of frames per second for a given workload, in an embodiment. |
