Embodiment Construction

[0010] Such as figure 1 Shown is the functional block diagram of the system for adjusting CPU frequency of the present invention. The system adopts a layered architecture, which includes an application layer, a driver layer, a hardware abstraction layer, and a hardware platform. The application layer includes the user interface 10 and the dynamic link library 11; the driver layer includes the driver model 12; the hardware abstraction layer includes the basic input output system (BIOS) 13 and the flash memory 14, where the BIOS 13 includes a frequency update module 130 and a data access module 131 ; The hardware platform includes South Bridge 15 and Central Processing Unit (CPU) 16. The user interface 10 is used to display the frequency of the CPU 16, the user intuitively adjusts the frequency of the CPU 16 through the user interface 10, and the user interface 10 outputs command signals to the dynamic link library 11 according to the user's operation. The dynamic link library 11 i...

Abstract

This invention discloses one CPU frequency system and its method, wherein, the system adopts layer structure, which comprises one application layer, one driving layer, one hardware abstraction layer and one hardware platform bench, wherein, the application layer comprises one user interface to display the CPU frequency and for user to adjust the CPU frequency freely and to output one CPU update frequency order signal according to user operations; the hardware abstraction layer comprises one BIOS to respond to the order signals and to provide the CPU frequency adjusting function. The invention adopts layer structure and provides the function to the BIOS to make the developer obey the standard interface to realize the compatibility of the BIOS of different types.

Description

【Technical Field】 [0001] The present invention relates to a system and method for adjusting CPU parameters, in particular to a system and method for adjusting CPU frequency. 【Background technique】 [0002] In practical applications, different applications require different central processing units (Central Processing Unit, CPU) to run at different speeds. For example, the running speed of the CPU required by a general file editing program is low. However, when a computer is used for image data processing, or for large data exchanges such as web browsing, the CPU must run at a higher speed to meet program performance. The power consumption, heat generation, and noise of accessories differ greatly under different operating speeds. In order to save energy, reduce heat generation, and improve CPU performance, the frequency of the CPU needs to be adjusted according to actual application requirements. [0003] There are many devices and methods for adjusting CPU frequency on the market...
