Method for adjusting working frequency of CPU

Abstract

This invention discloses a method for adjusting the working frequency of the central process unit, which gradually adjust the CPU according to the CPU real time operation status. The method are the following: to establish a frequency stage conversion meter; to get a current using state data of CPU; to generate a stage value of target frequency according to the frequency conversion meter; to gradually adjust the working frequency to the target frequency stage value. This method can decrease human operation errors and make the CPU work at beat and decrease material waste and hardware loss.

Description

technical field [0001] The present invention relates to a kind of adjustment method related to working frequency (Clock Frequency), especially relates to a kind of in computer software program according to central processing unit use state data, then apply fuzzy control (Fuzzy Control) mode to gradually adjust central processing unit operating frequency method. Background technique [0002] The existing methods for adjusting the operating frequency (Clock Frequency) of the central processing unit, namely the so-called "overclocking" or "underclocking", are mostly adjusted by the user using manual operation, and the user must use The jumper is changed and adjusted by plugging and unplugging so that the required operating frequency circuit can be electrically connected so that the central processing unit can be replaced to the required operating frequency for operation. [0003] However, the way of artificially adjusting the operating frequency is likely to cause the followin...

Problems solved by technology

[0003] However, the way of artificially adjusting the operating frequency is likely to cause the following two problems: (1) Since the operating program executed by the central processing unit is constantly changing, a higher operating frequency is theoretically required to cope with the load when the load is heavy. Huge execution burden, and when the load is light, it is theoretically necessary to adjust the CPU to a lower operating frequency to save unnecessary resource consumption, and this phenomenon often causes the current artificial adjustment method to fail because it cannot be Grasp the load (loading) of the central processing unit and produce problems that cannot be adjusted to the optimum in real time and maintain the optimum operating frequency at any time; (2) because the user must refer to the manual before adjusting the operating frequency. The frequency modulation work can be carried out smoothly, not only the operation procedure is quite cumbersome, but also it is easy to cause frequency modulation errors due to the lack of relevant knowledge of the user. When the frequency modulation is excessive or insufficient, it will often cause an additional burden on the operation of the central processing unit. Therefore, through artificial adjustment work The frequency method is more error-prone and easy to cause unnecessary loss of related hardware components, resulting in the problem of reducing the service life time

[0004] In order to reduce the above-mentioned many problems of artificially adjusting the operating frequency, there is now a practice of adjusting the operating frequency by providing a computer software program interface. Although this method can prevent users from directly contacting difficult and difficult hardware components, it can also simplify the use. operator's operating procedures, but also because of the inability to provide real-time adjustments and methods to maintain optimization at any time, the problem of hardware component wear and tear may still occur
