Power-subsystem-monitoring-based graphics processing system
A power-subsystem-monitoring-based computing system includes a power subsystem coupled to a first computing component. A throttling engine throttles the first computing component when the power subsystem exceeds its maximum power consumption, and de-throttles the first computing component when the power subsystem no longer exceeds its maximum power consumption. The throttling engine also throttles the first computing component when the power subsystem exceeds its rated power consumption for a first time period, and de-throttles the first computing component when the power subsystem no longer exceeds its rated power consumption. The throttling engine also reduces the operating capabilities of the first computing component when throttling has been performed for more than a second time period, and increases the operating capabilities of the first computing component when the throttling has been performed for less than the second time period and the first computing component is operating below its desired operating capability.
