US 2018/0120923 A1 · USAGE PATTERN BASED SUPERVISORY CONTROL OF POWER MANAGEMENT

Abstract

A supervisory control system provides power management in an electronic device by providing timeout periods for a hardware component to lower levels of the operating system such as a power management arbitrator and/or a hardware interface controller. The timeout periods are chosen based on usage patterns detected on the electronic device and based on user preference information. The power management arbitrator and/or hardware interface controller transition at least a portion of a hardware component to a lower-power state based on monitored activity information of the hardware component. The supervisory control system may further provide wakeup periods to the power management arbitrator and/or a hardware interface controller to determine whether the hardware component should be transitioned to a higher power state at the end of the wakeup period if the hardware component satisfies a transition condition.

Dependent claims

An adaptive power management method for power management of an electronic device, the adaptive power management method comprising:

receiving operational information of one or more applications executing on the electronic device, the one or more applications interacting with a hardware component of the electronic device;
determining a usage pattern of the hardware component by the one or more applications based on the received operational information;
setting a timeout period associated with the hardware component of the electronic device based on the determined usage pattern, the timeout period defining a minimum amount of time before a power state of the hardware component is permitted to be transitioned from a higher-power state to a lower-power state;
and
transitioning at least a portion of the hardware component from the higher-power state to the lower-power state after expiration of the timeout period if the hardware component satisfies a transition condition, the transition condition being dependent at least in part on the operational information and the timeout period.

an operational information receiver configured to receive operational information of one or more applications executing on the electronic device, the one or more applications interacting with a hardware component of the electronic device;
a usage pattern module configured to determine a usage pattern of the hardware component by the one or more applications based on the received operational information;
and
a timeout period selector configured to set a timeout period associated with the hardware component of the electronic device based on the usage pattern, the timeout period defining a minimum amount of time before a power state of the hardware component is transitioned from a higher-power state to a lower-power state.
