ADAPTIVE FRAME RATE CONTROL FOR A GRAPHICS SUBSYSTEM

摘要

Examples are disclosed for adjusting a performance state of a graphics subsystem and/or a processor based on a comparison of an average frame rate to a target frame rate and also based on whether the graphics subsystem is in a burst mode or sustained mode of operation.

主权项

1. A method comprising:
gathering, by a process circuit, first separate render times for one or more frames rendered by a graphics subsystem for a computing platform; determining a first average render time for the first separate render times based on whether the first separate render times have been gathered for at least a first time interval; determining whether the graphics subsystem is operating in either a burst mode or a sustained mode based on a comparison of the first average render time to a target render time; determining a first average frame rate over the first time interval based on a determination of sustained mode for the graphics subsystem; and determining whether to adjust a performance state associated with the graphics subsystem based on a comparison of the first average frame rate to a target frame rate.
