Abstract

An apparatus, method, and computer-readable media are provided for reducing an energy consumption of hardware on which an application is running. In use, a call is received from an application via anapplication program interface. Such call indicates a state of the application. Further, an action is determined, based on the call. The action is for reducing an energy consumption of hardware on which the application is running. The method continues by executing the action for reducing the energy consumption of the hardware on which the application is running.

Description

[0001] This application claims a prior application to U.S. Nonprovisional Patent Application Serial No. 15 / 448,396, entitled "Apparatus and Method for Reducing Hardware Energy Consumption Based on Application State," filed March 2, 2017 Priority, the entire contents of which are incorporated herein by reference. technical field [0002] The invention relates to energy consumption management, in particular to a technology for reducing energy consumption. Background technique [0003] In recent years, many techniques have been proposed to improve the energy efficiency of mobile devices. One technique is called dynamic voltage and frequency scaling (DVFS). This circuit-level technique regulates power consumption by dynamically adjusting the voltage and / or frequency of the device. A driver-level software module called a regulator can monitor circuit-level factors such as processor load and switch to a certain frequency and / or voltage when such load exceeds a threshold. [000...
