Problems solved by technology

[0007] When a state switch occurs, the terminal will always enter the Normal state with a fixed operating frequency (including CPU operating frequency, DSP operating frequency, bus operating frequency or related module operating frequency, etc.), but for some tasks executed in the Normal state, some tasks only It can be processed normally at a low operating frequency. Since the operating frequency is proportional to the dynamic power consumption value of the terminal, if the terminal always enters the Normal state at a fixed operating frequency, it actually leads to unnecessary waste of power consumption.

Embodiment 1

[0026] figure 1 Shown is a flowchart of a terminal power consumption control method according to an embodiment of the present invention, including the following steps:

[0027] S101. When the terminal receives a trigger to switch to a standard working state, acquire a type of a trigger condition for switching.

[0028] First, a brief description of the switching process of the terminal working state is given. figure 2 Shown is a schematic diagram of the switching conditions of the terminal between various states. When the terminal is in the Sleep state, if it receives an interrupt, it will wake up and enter the Slow state. The interrupt can be divided into DRX interrupt and non-DRX interrupt.

[0029] The DRX interruption is periodic. According to the specific communication network environment, the DRX cycle range is generally set at 80ms-2560ms. When the terminal receives the DRX interrupt, it will execute the corresponding DRX tasks, mainly including the detection of pagi...

Embodiment 2

[0054] Corresponding to the above method embodiment, the embodiment of the present invention also provides a terminal power consumption control device, see image 3 shown, including:

[0055] The trigger condition type acquisition unit 310 is used to acquire the type of the switch trigger condition when the terminal receives a trigger to switch to the standard working state;

[0056] The frequency setting unit 320 is used to set the operating frequency according to the type of the acquired switching trigger condition; the operating frequency may include: CPU operating frequency, DSP operating frequency, system bus operating frequency, peripheral interface operating frequency, storage device operating frequency frequency and memory operating frequency, etc.

[0057] Wherein, the frequency setting unit 320 can set the working frequency according to the preset correspondence between the switching trigger condition type and the working frequency.

[0058] The specific scheme of ...

Abstract

The invention discloses a method and a device for controlling the terminal power consumption, wherein, the method has the step of obtaining the type of a shift toggle condition when a terminal receives the toggle shifting into a standard working condition, as well as the step of setting working frequency according to the obtained type of the shift toggle condition; and the working frequency comprises the working frequency of a treatment unit and (or) the working frequency of a system bus. Compared with the prior art, when the terminal is shifted into a Normal state, the device can not be run on the same frequency, the concrete type of the shift toggle condition needs to be firstly judged before the operation of shifting, and the corresponding working frequency is selected according to the type of the toggle condition, therefore, the working frequency of the terminal shifted into the Normal state can be matched with the frequency required for executing function at latter time, thus realizing the optimizing control of the power consumption and reducing the integral power consumption of the terminal.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and device for controlling power consumption of a terminal. Background technique [0002] In recent years, embedded terminals such as mobile phones and PDAs (Personal Digital Assistants) have been integrated into people's daily life. As the function of the terminal becomes more and more powerful, the power consumption requirement of the terminal is also higher and higher; on the other hand, the terminal's energy supply is limited due to the user's portable demand for the terminal. The goal of low power consumption design for embedded devices is to reduce the power consumption of the device as much as possible on the premise of meeting the performance requirements of users, so as to solve the contradiction between high performance and limited battery energy. [0003] In the prior art, a solution for controlling terminal power consumption is to set multip...
