Techniques for managing system power using deferred graphics rendering

摘要

An apparatus may include a memory to store one or more graphics rendering commands in a queue after generation. The apparatus may also include a processor circuit, and a graphics rendering command manager for execution on the processor to dynamically determine at one or more instances a total execution duration for the one or more graphics rendering commands, where the total execution duration comprises a total time to render the one or more graphics rendering commands. The graphics rendering command manager also may be for execution on the processor to generate a signal to transmit the one or more graphics rendering commands for rendering by a graphics processor when the total execution duration exceeds a graphics rendering command execution window.

1. An apparatus, comprising:
a memory to store one or more graphics rendering commands in a queue after generation; a processor; and a graphics rendering command manager for execution on the processor to:
dynamically determine at one or more instances in a graphics frame a total execution duration for the one or more graphics rendering commands, the total execution duration comprising a total time to render the one or more graphics rendering commands; andgenerate a signal to transmit the one or more graphics rendering commands for rendering by a graphics processor and to wake up the graphics processor from a low power state when the total execution duration exceeds a graphics rendering command execution window based on a decreasing remaining interval before an end of the graphics frame and based on an amount of time required to wake up the graphics processor from the low power state.
