Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The present invention discloses a kind of method regulating CPU frequency of operation, and the method is applied to the mobile terminal running Android system.Based on method disclosed by the invention, the power consumption of CPU in mobile terminal can be reduced further, extend the cruising time of mobile terminal.
Mobile terminal can run multiple task simultaneously, and wherein partial task is in running background, only has minority task to be in front stage operation, that is, in running of mobile terminal process, only has minority task carrying out alternately with user.For user, whether the operation that user only pays close attention to current mutual task is smooth, and is in the task of background operation state, and user does not pay close attention to.Therefore, can according to the current frequency of operation regulating CPU with the task of user interactions, reduce the task of running background to the impact of CPU frequency of operation, both ensure that Consumer's Experience like this, also reduce further the frequency of operation of CPU, thus reduce the power consumption of CPU, extend the cruising time of mobile terminal.
Be a kind of process flow diagram regulating the method for CPU frequency of operation disclosed by the invention see Fig. 1, Fig. 1.The method is applied to the mobile terminal running Android system, and the method comprises:
Step S11: determine currently to be in front stage operation task.
In running of mobile terminal process, the task of running of mobile terminal has multiple, determine the task of being in front stage operation in multiple task, namely determines the current task with user interactions in multiple task.
Step S12: the mapping relations utilizing task and the task type prestored, determines the task type of task.
Mobile terminal prestores the mapping relations of task and task type, after determining the current task with user interactions, just can determine task type that the is current and task of user interactions according to these mapping relations.In enforcement, task type can include but not limited to that audio frequency plays type, video playback type, e-book type and social application type.
Step S13: the mapping relations utilizing task type and the CPU frequency of operation prestored, determines the CPU frequency of operation corresponding with task type.
Mobile terminal also prestores the mapping relations of task type and CPU frequency of operation, and in these mapping relations, each task type all has corresponding CPU frequency of operation.It should be noted that, the CPU frequency of operation corresponding with task type, can ensure that the task of this task type can smoothly be run, and the electric energy that CPU consumes is minimum.That is, the CPU frequency of operation corresponding with task type is the minimum CPU frequency of operation that can ensure that the task smoothness of this task type is run.
In enforcement, the mapping relations of task type and CPU frequency of operation, can be determined by the mode of verification experimental verification in process of production by equipment vendors, also in use can be obtained by self study by mobile terminal.
Step S14: the frequency of operation utilizing the CPU frequency of operation configuration CPU corresponding with task type.
Determine with the task type of the task of user interactions after, determine the CPU frequency of operation that this task type is corresponding, utilize afterwards determine CPU frequency of operation configuration CPU frequency of operation.
The method of adjustment CPU frequency of operation disclosed by the invention, first task that is current and user interactions is determined, determine the task type of this task afterwards, determine the CPU frequency of operation corresponding with this task type afterwards, utilize the CPU frequency of operation determined to configure the frequency of operation of CPU.In the method for adjustment CPU frequency of operation disclosed by the invention, CPU frequency of operation is configured with the task of user interactions according to current, therefore, the task of running background can be reduced on the impact of CPU frequency of operation, thus reduce the frequency of operation of CPU, the power consumption of reduction CPU further, and then extend cruising time of mobile terminal, and can not affect with the travelling speed of the task of user interactions, therefore still can ensure Consumer's Experience.
