Identification of GPU phase to determine GPU scalability during runtime

摘要

A method performed by a processor is described. The method may include identifying a graphics processing unit (GPU) phase of a frame, using said identified GPU phase to obtain frequency scalability information for said identified GPU phase, and determining whether to change a frequency at which a GPU is to draw said frame within said phase based on said frequency scalability information.

1. A method performed by a processor comprising:
identifying a plurality of graphics processing unit (GPU) phases of a frame; defining a frequency scalability function of performance versus frequency for each of said plurality of identified GPU phases; separately tracking frequency scalability information for each GPU phase of the plurality of GPU phases in a phase profile database; and determining whether to change a frequency at which a GPU is to draw said frame within said plurality of identified GPU phases based on said frequency scalability functions.
