Abstract

The invention discloses a method and a device for balancing multi-core CPU load. The method comprises the following steps of acquiring utilization rate information and frequency information of each CPU core in the multi-core CPU; acquiring a first CPU core with the frequency satisfying the operation condition of a to-be-operated process and lowest utilization rate; configuring the to-be-operated process into the first CPU. By adopting the embodiment, after the load balance of multi-core CPU is carried out, the increment of the power consumption can be avoided.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of multi-core CPU (Central Processing Unit, central processing unit), and in particular to a method and device for multi-core CPU load balancing. Background technique [0002] Due to power consumption considerations, especially the limited battery power supply capacity of embedded devices, modern CPUs often use the DVFS (Dynamic voltage and frequency scaling) mechanism to dynamically adjust the CPU frequency. Reduce power consumption. The adjustment of the CPU frequency is based on the utilization rate of the CPU, which specifically includes: when the utilization rate of the CPU core is greater than the upper limit utilization rate, increase the frequency of the CPU core; when the CPU core utilization rate is lower than the lower limit utilization rate , reduce the frequency of the CPU core. Wherein, the utilization rate refers to the ratio of the working ...
