Abstract

Methods and systems are provided for dynamically managing power consumption in a digital system. These methods and systems broadly provide for permitting clients executing on a digital system to register for notification of power event and to request that power events occur. Registered clients are notified when a power event is requested and the requested power event is caused to occur. Power events are selected from a group comprising setpoint change, enter deep sleep mode, enter snooze mode, and change to power supply status. There may also be user-defined custom power events. If the requested power event is a setpoint change, a check is made to verify that each of the registered clients can operate at the requested setpoint. The digital system may be comprised of processor with a single processing core with a single clock or a processor with multiple processing cores and multiple clocks.
