Problems solved by technology

[0004] In the prior art, the CPU in the mobile terminal generally uses a single ondemand mode for frequency modulation, but the frequency modulation speed of the ondemand mode is slow and requires level-by-level adjustments, which limits the performance of the mobile terminal and increases power consumption
For example, when a user uses a mobile terminal to play a game, the CPU needs to process a large amount of data, but due to the slow increase of the CPU frequency, the data required by the game is not processed in time, resulting in freezes or crashes; another example, when the mobile terminal is in idle mode (idle), in theory, only the minimum performance is required, but in ondemand mode, if there are processes running in the background, the load size will change, which will cause the CPU to continue to adjust frequency, which will increase power consumption and affect performance optimization

Description

technical field [0001] The invention relates to computer technology, in particular to a method and device for adjusting a CPU frequency modulation mode in a terminal. Background technique [0002] With the rapid development of mobile terminal technologies (for example, smart phones and tablet computers, etc.), the performance of mobile terminal processors is also improving accordingly, and correspondingly, the power consumption of mobile terminals is also increasing. [0003] The CPU (Central Processing Unit, Central Processing Unit) of the mobile terminal does not always run at one frequency, but adjusts the frequency according to actual needs, so that the CPU runs at different frequencies, so as to achieve the purpose of optimal power consumption and performance. Currently, the frequency modulation modes of the CPU mainly include the most power-saving mode (powersave), the on-demand setting mode (ondemand), and the highest performance mode (perform). [0004] In the prior...
