Abstract

The invention discloses a method and device for regulating CPU frequency of a portable terminal. The method comprises the steps that operation frequency of an application program to be operated is obtained, magnitude of operation frequency of the application program to be operated and magnitude of the present frequency of a CPU are judged, if the operation frequency is smaller than or equal to the present frequency of the CPU, the present frequency of the CPU is maintained, and if the operation frequency is higher than the present frequency of the CPU, the present frequency of the CPU is regulated to the operation frequency. According to the method and device, operation power dissipation of the CPU is lowered as much as possible, power consumption of the CPU is lowered, and endurance time of a battery is prolonged.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment, in particular to a method and device for adjusting the frequency of a central processing unit (CPU) of a portable terminal. Background technique [0002] With the popularity of computers and handheld terminals, more and more users will choose terminal devices such as smart phones, smart tablets, and personal computers to surf the Internet, entertain or work. With the continuous progress of the manufacturing industry and the emergence of integrated design, the manufacturing threshold of portable terminal equipment has been continuously lowered, and more and more companies have begun to manufacture and sell the above-mentioned portable devices. Users can use the portable terminal to perform various operations such as web browsing, document processing, reading e-books, and enjoying video and audio. Greatly facilitate the user. [0003] With the advancement of the semiconductor m...
