Title:
PROACTIVE POWER MANAGEMENT USING A POWER MANAGEMENT UNIT
Document Type and Number:
WIPO Patent Application WO/2013/026039
Kind Code:
A3
Abstract:
Embodiments of the present disclosure provide systems and methods for proactively managing power in a device. A power management unit (PMU) receives information from various subsystems of a device and estimates the total power required by each subsystem of the device. Based on this information, the PMU can predict power requirements for a particular subsystem or for one or more application(s) to execute. Based on this prediction, the PMU can reconfigure the subsystems so that the device executes more efficiently given the current battery life of the device. Proactive power management advantageously gives the PMU the capability to predict power needs of various subsystems of a device so that the power supplied to these subsystems can be managed in an intelligent way before battery resources are exhausted.
