Computer processing unit intra-frame clock and voltage scaling based on graphics application awareness
摘要:
Computer processing unit intra-frame clock and voltage scaling based on graphics application awareness is disclosed. The computer processing unit includes a processor configured to execute a graphics application to generate a graphics image for output to a display. The computer processing unit includes a power management circuit configured to perform clock and voltage scaling (CVS) (i.e., frequency and/or voltage scaling) for the processor. The power management circuit is configured to identify a graphics application dispatched to be executed or being executed by the processor and to set the operating point for the processor based on the identified graphics application. This may allow the processor to operate at a more optimal operating point for performance of graphics and non-graphics applications as opposed to operating each application at a lower operating point due to a graphics application that is more current intensive.
