Description

降低移动终端功耗的方法、装置及其终端 Method of reducing the power consumption of the mobile terminal, and the terminal apparatus

技术领域 FIELD

[0001] 本发明涉及通信技术领域,具体而言,涉及一种降低移动终端功耗的方法、装置及其终端。 [0001] The present invention relates to communication technologies, and in particular, relates to a method for reducing the power consumption of the mobile terminal, and the terminal device.

背景技术 Background technique

[0002] 随着移动终端(例如手机)功能的不断加强和完善,其在人们的生活中扮演着越来越为重要的角色,于是,如何降低手机的功耗,以使得手机的应用待机时间能够得到进一步地增长,便成为了手机制造商们目前需要解决的重要问题之一。 [0002] As mobile terminals (eg mobile phones) continue to strengthen and improve the function of which is playing an increasingly important role in people's lives, so how to reduce the power consumption of the phone so that the phone's standby time application can be further growth, it has become one of the important issues currently handset manufacturers need to be addressed.

[0003] 通常,手机低功耗方案包括工作状态下的低功耗以及空闲状态下的低功耗两种,工作状态下的低功耗是指:当某个设备空闲时关闭其时钟或电源,以达到降低功耗的目的,比如当不使用手机背光或键盘时将其背光关闭,不使用照相机camera功能时关闭camera模块的电源和时钟。 [0003] Usually, the low-power embodiment comprises two kinds of low-power and low power at the idle operating state, the low power operating state refers to: power off when it is idle clock or a device to achieve the purpose of reducing power consumption, such as when not using the mobile phone keypad to backlight or backlight off, turn off the power and clock module camera camera function camera is not used. 空闲状态下的低功耗则是指:当整个系统的外设及应用都处于空闲状态时,则整个系统进入休眠状态,也就是使系统所有能关闭的时钟或电源均关闭,不能关闭的则进入低功耗工作模式。 Low power consumption in the idle state refers to: when the peripherals and the application of the system is idle, the system enters the sleep state, i.e. so that all closable clock or power supply are turned off, is not closed enter low-power mode.

[0004] 因此,如何在各种不同的应用场景下使得手机能够进入相应的低功耗模式,且关闭相应的时钟或电源便是实现手机低功耗的关键。 [0004] Therefore, how to make a mobile phone in a variety of different application scenarios can enter a respective low-power modes, and closing the respective clock or power is critical to achieve low power consumption of the mobile phone.

[0005] 现有技术提供的电源管理方案,其一次只能操作一个电源模块,无法实现能够根据不同场景将相应的多个电源模块关闭,使多个电源模块进入低功耗模式,从而导致系统功耗较大。 [0005] The prior art power management scheme is provided which can only operate a power module can not be realized according to different scenes corresponding plurality of power modules are closed so that the plurality of power modules enter a low power mode, causing the system power consumption is large. 例如,有的电源芯片的电源模块关闭是通过I2C(Inter — Integrated Circuit,两线式串行总线)将值写到电源芯片中,从而使相应的电源模块关闭,然而该技术方案所存在的缺点是:操作I2C比较复杂,且操作I2C关闭电源模块需要一定的时间,这样势必会减少系统的睡眠时间,另外,若要同时关闭多个电源模块,则需要多次操作I2C,这样会大大减少系统的睡眠时间,导致功耗增大,而且在系统对时间要求比较严格的条件下,还会影响系统的运行时序。 For example, some power chip power module switched off by I2C (Inter - Integrated Circuit, two-wire serial bus) writes the value of the power chip, so that the corresponding power module switched off, but the present aspect disadvantages is: I2C operation is more complex, and the operation of the I2C off the power module will take some time, this will inevitably reduce the sleep time of the system, in addition, to close multiple power modules at the same time, you need multiple operations I2C, it would greatly reduce system sleep time, power consumption increases, and the time required for the system under more stringent conditions, will also affect the operation of the timing system.
