Limited.On the contrary, it is provided that these embodiments are able to be best understood from the disclosure, and can be by the scope of the present disclosure
Complete conveys to those skilled in the art.
Embodiment one
With reference to Fig. 1, it is shown that the flow chart of steps of a kind of central processing unit control method of the embodiment of the present invention one.
The central processing unit control method of the embodiment of the present invention comprises the following steps:
Step 101: obtain the current temperature value of mobile terminal.
CPU control method in the embodiment of the present invention is suitable for inclusion in the mobile terminal of many kernels CPU.The embodiment of the present invention
In the particular number of kernel that CPU is comprised be not especially limited.Such as: CPU can comprise 8 kernels, 4 kernels etc..
Mobile terminal is bringing into operation and all can adjust kernel in CPU according to current temperature value in running
Run quantity.When carrying out the control of kernel operation quantity in CPU, perform the CPU control flow in the embodiment of the present invention i.e. every time
Can.
The current temperature value of the mobile terminal obtained can be the internal current temperature value of mobile terminal, it is also possible to for movement
Terminal surrounding current environmental temperature value, is not specifically limited this in the embodiment of the present invention.
Step 102: determine the temperature range belonging to current temperature value.
Mobile terminal is preset with the corresponding relation of temperature range and kernel operation quantity, therefore, this step needs really
Determine the temperature range belonging to current temperature value, it is simple to further determine that kernel runs quantity.
Step 103: determine the kernel operation quantity that temperature range is corresponding.
After determining temperature range, run the corresponding relation between quantity according to temperature range and kernel, in i.e. can determine that
Core runs quantity.In the embodiment of the present invention, the corresponding relation that temperature range and kernel are run quantity is not especially limited.For
The higher limit of each temperature range is not restricted with lower limit.
When the arranging of corresponding relation carrying out temperature range and kernel operation quantity, it then follows temperature value runs number with kernel
The principle that value is inversely proportional to, the i.e. temperature of temperature range instruction are the highest, then the kernel operation quantity of its correspondence is the fewest.
Step 104: the kernel of this quantity control in CPU, determining is in running status.
Such as: determine that 4 kernels run, if CPU comprises 8 kernels, when CPU is controlled, then control 4 in CPU
Individual kernel runs, and 4 other kernels are then controlled in a dormant state.
It should be noted that run or during dormancy at the kernel controlled in CPU, can be come by the frequency adjusting kernel
Realize.

With reference to Fig. 2, it is shown that the flow chart of steps of a kind of central processing unit control method of the embodiment of the present invention two.
The central processing unit control method that the embodiment of the present invention provides specifically includes below scheme:
Step 201: receive the setting that the kernel that each temperature range and each temperature range are corresponding is run quantity.
CPU control method in the embodiment of the present invention is suitable for inclusion in the mobile terminal of many kernels CPU.The embodiment of the present invention
In comprise by CPU and to illustrate as a example by 8 kernels.It should be noted that during implementing, the embodiment of the present invention provides
CPU control method, it is not limited to the CPU comprising 8 kernels is controlled, it is also possible to the kernel comprising other quantity
CPU be controlled.
A kind of preferred temperature range is as follows with the set-up mode of the corresponding relation that kernel runs quantity:
Arranging temperature range is 40 degree of extremely infinities, and in corresponding CPU, all kernels are in resting state；
Arranging temperature range is 30～40 degree, the kernel of the middle half quantity of corresponding CPU in a dormant state, half quantity
Kernel be in running status；
