Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The main solution of the embodiment of the present invention is to obtain the CPU working state information of the mobile terminal multiple times periodically, calculate the real-time utilization rate of the CPU, judge the system load trend according to the real-time CPU utilization rate, and adjust the CPU frequency and CPU frequency according to the trend. The number of cores, thus effectively reducing the number of times of frequency modulation and core adjustment operations without affecting the user experience, and realizing effective control of the number of frequency conversion operations of the system. Moreover, after predicting the system load trend, by adjusting the CPU frequency and the number of CPU cores in advance, the fluency of the system can be improved and the user experience can be improved. ...

Abstract

The invention discloses a dynamic power management method, a mobile terminal and a storage medium. The method comprises: acquiring CPU working state information of the mobile terminal according to a preset time period; The ratio of the total time to get the CPU utilization; judge the trend of the system load based on the CPU utilization; adjust the CPU operating frequency and the number of CPU cores according to the trend of the system load. The present invention effectively reduces the occurrence times of frequency modulation and core adjustment operations without affecting user experience, and realizes effective control of the frequency conversion operation times of the system. And after predicting the system load trend, by adjusting the CPU frequency and the number of CPU cores in advance, the fluency of the system can be improved and the user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a dynamic power management method, a mobile terminal and a storage medium. Background technique [0002] At present, as the screens of mobile terminals become larger and more functional, and the development of battery technology is relatively slow, the battery life of mobile terminals appears to be insufficient, so dynamic power management strategies are particularly important. In addition to the simplest greedy strategy, the commonly used dynamic power management strategies can be roughly divided into three categories: timeout strategy, predictive strategy and stochastic model optimization strategy. [0003] Among them, the Powersave and Performance strategies can be considered as two extreme greedy strategies. The former fixes the CPU at the lowest frequency supported by the hardware to achieve the greatest pursuit of low power consumption, and the latter fixes the CPU...
