Abstract

The invention provides a frequency management method and device for a multicore CPU (Central Processing Unit). The method comprises the following steps: periodically acquiring a frequency change set of frequencies according to which the multicore CPU in a terminal is adjusted dynamically under a specified running scene; and performing statistics on the frequencies in the frequency change set according to a preset calculation model, and acquiring a best frequency adjustment range of the multicore CPU under the specified running scene according to a statistical result. Through adoption of the frequency management method and device, the problem of incapability of finding an appropriate adjustment frequency by automatic frequency adjustment when an interactive frequency adjustment method is adopted for the frequency adjustment of the multicore CPU inside the terminal in the prior art is solved, and the effect of lowering the power consumption of the multicore CPU in the terminal is achieved.

Description

technical field

[0001] The invention relates to the field of computers, in particular to a frequency management method and device for a multi-core processor CPU. Background technique

[0002] At present, general intelligent terminal manufacturers, the frequency adjustment of the multi-core CPU inside the terminal adopts the conventional technical solutions of chip manufacturers by default, that is, interactive, powersave, performance, userspace and other control algorithm mechanisms.

[0003] However, among the above-mentioned control algorithm mechanisms currently provided by chip manufacturers, most terminal manufacturers will choose the default interactive control algorithm, because the algorithm mechanism is characterized by "fast rise and slow fall", that is, when there is a high demand, it will jump quickly. To high frequency, gradually reduce to low frequency when the demand is low, focusing on the response speed and performance of the priority protection terminal. B...
