Title: POWER SUPPLY VOLTAGE PRIORITY BASED AUTO DE-RATING FOR POWER CONCURRENCY MANAGEMENT
Abstract:
Particular embodiments include logic that can reduce an voltage output of a regulator to multiple subsystems in response to detecting high power conditions in an electronic device. When the power being monitored goes up, the logic detects the increase in power. Then, the logic can compare the power to a plurality of thresholds. The plurality of thresholds may be set below an absolute limit threshold in which the electronic device may not operate properly if the absolute limit is met. When a first threshold is met, the output voltage of the regulator may be decreased until a minimum voltage level is reached. When a second threshold is met, the output voltage may be increased until a maximum voltage level is reached. The minimum and maximum voltage levels may be based on voltage levels requested from a set of subsystems and also priority levels associated with those subsystems.
