Control method of terminal power consumption and terminal

Abstract

The invention relates to the field of communication, which discloses a regulating method of power consumption of a terminal as well as the terminal. In the invention, the method comprises the steps of: when a service is registered or cancelled, obtaining the total clock frequency currently and accurately needed according to the sum of frequency increment of all services currently registered and a basic frequency; further determining the power consumption grade of the terminal and configuring the terminal with corresponding frequency and voltage of the terminal in the power consumption grade. According to the invention, the power consumption of the terminal can be adjusted in real time with smaller resource consumption, and the method is simple to realize and strong in adaptability and takes effect immediately. The system operates in the optimal balance point of efficiency and power consumption, so that the service sensitivity of power consumption of the terminal is realized to the benefit of saving power for the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to the terminal power consumption control technology in the communication field. Background technique [0002] Terminal power consumption generally uses P=ΣC*F*V 2 To calculate, where, C is the parasitic capacitance, F is the clock frequency, V is the operating voltage. It can be known from this formula that the power consumption of the system is the sum of the power consumption of each sub-module. For each sub-module in a terminal system, C is fixed, and the clock frequency and voltage are the key factors of power consumption; for the system, the power consumption of the peripherals is controlled by the corresponding drivers and applications, and the main CPU of the system ( The central processing unit) is a public resource. If the operating clock frequency and the power supply voltage of the CPU are adjusted according to various services or service combinations, the power consu...

Problems solved by technology

[0007] It can be seen that if the power consumption of the terminal is regulated by using the service collection table lookup method, for various local services, there are many combinations and it is difficult to make a table; The table is not easy to change, especially for the terminal solution platform, it is not easy for customers to operate

[0008] If the CPU usage judgment method is used to regulate the power consumption of the terminal, the determination of the power consumption level has a lag, which is only applicable to the application processor side of the smart terminal, and the CPU statistics itself occupies CPU resources.
