Abstract

The invention discloses a method for adjusting the basic frequency of a central processing unit (CPU) and a device thereof. The method comprises: acquiring the average utilization rate of the CPU within the set time; and adjusting the basic frequency of the CPU according to the average utilization rate as well as the preset first utilization rate threshold value and second utilization rate threshold value. The device comprises an average utilization rate acquisition unit used for acquiring the average utilization rate of the CPU within the set time, and a basic frequency adjusting unit used for adjusting the basic frequency of the CPU according to the average utilization rate as well as the preset first utilization rate threshold value and second utilization rate threshold value. The method and the device can effectively acquire the real-time average utilization rate of the CPU by continuously monitoring the CPU, and can adjust the basic frequency of the CPU according to the real-timeaverage utilization rate in a self-adapting way, thus ensuring the CPU to have high basic frequency when the average utilization rate is higher and meeting the using performance of the CPU and have low basic frequency when the average utilization rate is lower, so that the effect of saving energy can be achieved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for adjusting the main frequency of a central processing unit which are beneficial to energy saving. Background technique [0002] Along with the rapid development of computer and network technology, servers have been widely used, such as Web (World Wide Web, referred to as Web) server, FTP (File Transfer Protocol, file transfer protocol) server, mail server, anti-virus server, etc. Wait. The server plays an important role in the contemporary information society. In order to improve the computing and processing capabilities of the server, the CPU (Central Processing Unit, central processing unit) frequency (clock frequency, the unit is MHz or GHz) is designed to be higher and higher. For example, the main frequency of Intel Xeon X5570 reaches 2.93GHz. Although various CPU manufacturers try to reduce power consumption as much as possible while improving pro...
