Embodiment Construction

[0026] The principle of the power management method of the portable electronic device of the present invention is to bring the processing action of the program being executed by the portable electronic device into the control range of power management, so that the portable electronic device can save more energy and improve the program accordingly The reaction time after the processing action is resumed.

[0027] The above principle can be figure 1 timing diagram to illustrate. exist figure 1 , the horizontal axis is the time axis, and the solid arrows on the time axis respectively represent events occurring at a certain time point, such as events 110 , 112 , 114 and 120 . The dotted arrows respectively represent events (such as event 130 ) that can be avoided when using the power management method of the present invention, whereby the portable electronic device can save more energy. In this example, the portable electronic device displays an animation composed of a pluralit...

Abstract

A portable electronic device and its power management method, which incorporates the processing actions of the program being executed by the portable electronic device into the power management control range, so that the portable electronic device can save more energy and improve the performance of the program. The reaction time after a processing action is resumed.

Description

technical field [0001] The present invention relates to a portable electronic device and its power management method, and in particular to a power management method of the portable electronic device to reduce power consumption. Background technique [0002] With the miniaturization of core computing chips and components, portable electronic devices, such as mobile phones, personal digital assistants, digital cameras and MP3 players (MPEG- 3 player) and so on, most of them have diversified functions to meet the increasing needs of users. The reason why such a portable electronic device can provide a variety of functions, in addition to the hardware design, the portable electronic device itself has a programmable function or an operating system, so that various applications can be used according to executed according to the needs of the reader. [0003] Portable electronic devices, such as mobile phones, emphasize power saving or low power consumption functions to increase t...
