Abstract

The invention discloses a method and a system for regulating and controlling a multi-core central processing unit (CPU). The method comprises the following steps of: setting CPU regulation and control modes which are used for regulating CPU startup quantity, CPU operation frequency and process migration in advance, wherein the CPU regulation and control modes comprise a predefined regulation and control mode and an automatic regulation and control mode; and performing switching on, switching off, frequency modulation and process migration control on CPU cores of the multi-core CPU in the CPU regulation and control modes through a bottom-layer core interface. According to the method and the system, the predefined regulation and control mode and the automatic regulation and control mode of the multi-core CPU are provided, so that mobile equipment can regulate on-and-off states, the frequency and process migration of the CPU automatically or in the predefined mode according to the service condition of the CPU of the mobile equipment; and by the method and the system, a user of the mobile equipment can select to input an instruction to regulate and control the operating condition of each CPU core of the multi-core CPU in different scenes, so that the processing capability of the multi-core CPU is improved or the aims of energy conservation and electricity saving are fulfilled.

Description

technical field [0001] The invention relates to the communication field, in particular to a multi-core CPU control method and system. Background technique [0002] It has become a trend to use dual-core and quad-core processors for mobile devices such as Android system smartphones and tablet computers. Since multi-core CPUs have certain advantages in processing capabilities, multi-core CPUs are more and more widely used in mobile devices. However, while the multi-core CPU brings a certain performance improvement to the mobile device, it also makes the bottleneck of the mobile device in terms of power more prominent. [0003] At present, multi-core smartphones with Android system generally schedule task processes to multiple cores of the multi-core CPU according to a "load balancing mechanism". However, under this "load balancing mechanism", even if the mobile phone is idle or in a low power state, the multi-core of the multi-core CPU is always in the running state, which ma...
