Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method and system for dynamically controlling the frequency of a processor in view of the deficiencies in the prior art. Through this method, it can solve the existing problem when the processor is running a high-load application program. , unable to switch from a low operating frequency to a high operating frequency as the load increases, resulting in stuck problems during the execution of the application
At the same time, it solves the problem that when the processor is running a low-load application program, it cannot switch from high operating frequency to low operating frequency as the load decreases, resulting in waste of processor power consumption.

Abstract

The present invention discloses a method and system for dynamically controlling a frequency of a processor. by presetting a multi-level instruction processing cache and a multi-level processor operating frequency on a processor, a current storage state of the multi-level instruction processing cache is detected, wherein the storage state of the multi-level instruction processing cache is positively correlated with the processor operating frequency; the processor operating frequency is adjusted according to the storage state of the multi-level instruction processing cache; and resources of the processor can be utilized reasonably, so that overall energy consumption is reduced. When a relative processing operating frequency of storage of the multi-level instruction processing cache of the processor is excessively high, the processor operating frequency is adjusted to the processor operating frequency corresponding to the instruction processing cache so as to guarantee various applications to smoothly run; and moreover, when the relative operating frequency of storage of the multi-level instruction processing cache is low, the processor operating frequency is adjusted to the processor operating frequency corresponding to the instruction processing cache.

Description

technical field [0001] The present invention relates to the technical field of terminal processing, in particular to a method and system for dynamically controlling processor frequency. Background technique [0002] With the rapid development and popularization of smart terminals (such as smart phones, tablet computers, etc.), more and more users use smart terminals to perform various operations such as web browsing, document processing, reading e-books, and enjoying video and audio. Great convenience for users. [0003] In practical applications, processors required by different applications, such as central processing units (Central Processin Unit, CPU) or microprocessors, have different operating speeds (or operating frequencies). For example, a general file editing program requires a relatively low processor speed, but when processing large amounts of data such as image data processing or web browsing, the processor must run at a higher speed to meet the program require...
