Abstract
Power gating a portion of a graphics processor may be used to improve performance or to achieve a power budget. A processor granularity, such as a slice or subslice, may be gated.
Claims27
A method comprising:
- determining a performance measure of a graphics processor in a larger configuration without power gating;
- power gating one of two hardware portions of a graphics processor;
- determining performance of the graphics processor with power gating;
- determining in the graphics processor if the graphics processor performance was improved by power gating compared to graphics processor performance without power gating to determine the effect of graphics processor power gating by comparing performance of the graphics processor with and without any power gating;
- and
- transitioning to a smaller configuration, with power gating, only if leakage savings of the smaller configuration exceed dynamic power cost due to increased frequency operation in the smaller configuration.

A non-transitory computer readable medium storing instructions for execution by a computer to:
- determining a performance measure of a graphics processor in a larger configuration without power gating;
- power gating one of two hardware portions of a graphics processor;
- determining performance of the graphics processor with power gating;
- determining in the graphics processor if the graphics processor performance was improved by power gating compared to graphics processor performance without power gating to determine the effect of graphics processor power gating by comparing performance of the graphics processor with and without any power gating;
- and
- transitioning to a smaller configuration, with power gating, only if leakage savings of the smaller configuration exceed dynamic power cost due to increased frequency operation in the smaller configuration.
3 more elements
A graphics processor comprising:
- first and second independently gateable hardware portions of the graphics processor;
- and
- logic to power gate one of two portions of a graphics processor and to determine a performance measure of a graphics processor in a larger configuration without power gating, determine performance of the graphics processor with power gating, determine if the graphics processor performance was improved by power gating compared to performance without power gating to determine the effect of graphics processor power gating by comparing performance of the graphics processor with and without any power gating and transition to a smaller configuration, with power gating, only if leakage savings of the smaller configuration exceed dynamic power cost due to increased frequency operation in the smaller configuration.
