Problems solved by technology

[0004] However, it is not convenient to manually set the PL2 value to optimize it. At the same time, the manual setting of the PL2 value is not safe, and it may cause the CPU to run at an unsafe power consumption, thereby causing the CPU to be damaged.

Embodiment Construction

[0040] For the sake of reference and clarity, the technical terms, abbreviations or abbreviations used in the following text are summarized as follows:

[0041] TDP: The full English name is ThermalDesign Power, that is, thermal design power consumption. It is mainly provided to computer system manufacturers, heat sink / fan manufacturers, and chassis manufacturers, etc. for system design. Generally, TDP is mainly used in CPU, and the CPU TDP value corresponds to the highest heat dissipation heat that the final version of the series CPU may achieve at full load (theoretically, the CPU utilization rate is 100%). The radiator must ensure that the processor TDP is at its maximum. The temperature of the processor is still within the design range.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the describ...

Abstract

The invention discloses a CPU power consumption limit value optimizing method and electronic device. The CPU power consumption limit value optimizing method comprises, after an optimizing instructionfor indicating power consumption limit value optimization of a CPU is acquired, acquiring the maximum clock frequency that the CPU can support, and information of default safety parameters of the CPU,and based on the maximum clock frequency and the information of the default safety parameters, optimizing the CPU power consumption limit value corresponding to the maximum turbo frequency of the CPU. Therefore, the CPU power consumption limit value optimizing method is a scheme for automatically optimizing the CPU power consumption limit value corresponding to the maximum turbo frequency of theCPU, compared with manual optimizing manners in the prior art, the automatic scheme can be convenient and fast; due to the fact, during automatic optimization, the information of the default safety parameters of the CPU are taken into consideration, the CPU power consumption limit value optimizing method can effectively prevent the CPU from running under unsafe conditions and further ensure safetyof the CPU.

Description

technical field [0001] The invention belongs to the technical field of CPU (Central Processing Unit, central processing unit) performance optimization, and in particular relates to a method for optimizing CPU power consumption limit and electronic equipment. Background technique [0002] CPU frequency refers to the clock frequency when the CPU core is working, which can be divided into main frequency and turbo frequency. Among them, the main frequency of the CPU indicates the speed at which the digital pulse signal oscillates in the CPU, which is not directly related to the actual computing power of the CPU; the CPU turbo frequency means that when a running program is started, the processor will automatically accelerate to an appropriate frequency , so that the original running speed will be increased by 10% to 20% to ensure the smooth running of the program, and the maximum turbo frequency refers to the highest frequency that the CPU can achieve when it is automatically tur...
