Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
For technical solutions according to the invention are described, below by specific embodiment, describe.
embodiment mono-:
Fig. 1 shows the realization flow of the mobile terminal CPU frequency modulation method that first embodiment of the invention provides, and details are as follows for its process:
In step S101, receive the outer frequency of mobile terminal CPU of input and/or the value of frequency multiplication.
In actual applications, mobile terminal can provide two input frames, the outer frequency of CPU that reception user inputs by described input frame and the value of frequency multiplication.
It should be noted that, the dominant frequency of mobile terminal CPU is the product of outer frequency and frequency multiplication, therefore by changing CPU any value frequently outer or frequency multiplication, can change the dominant frequency of CPU.
As a preferable examples of the present invention, outside the mobile terminal CPU that receives input, before the value of frequency and/or frequency multiplication, the present embodiment also comprises:
Display reminding information, the maximal value of prompting customer mobile terminal CPU frequency with and the value of the frequency multiplication of input should be the integral multiple of predetermined value.
In the present embodiment, because the value of CPU frequency multiplication is generally 0.5 integral multiple, so when user inputs the value of frequency multiplication, prompting user inputs 0.5 multiple value.After the value of mobile terminal CPU frequency multiplication that receives input, judge whether the value of inputted frequency multiplication is the integral multiple of predetermined value (as 0.5), if not, abandon the value of inputted frequency multiplication, and point out user input error, need to re-enter the value of frequency multiplication.
In addition, in order to prevent that CPU product frequently outer and frequency multiplication from exceeding the maximal value of CPU frequency.Preset the maximal value (be generally while dispatching from the factory the CPU frequency value set 1.1 times) of mobile terminal CPU frequency, outside user inputs CPU frequently and after the value of frequency multiplication, the product that calculates the two obtains the value of CPU frequency, if the value of this CPU frequency is greater than the maximal value of predefined mobile terminal CPU frequency, the maximal value of pointing out user's CPU frequency to exceed CPU frequency, need to re-enter the value of outer frequency and/or frequency multiplication.
It is larger that the CPU frequency that the present embodiment provides is revised scope, both can meet user for saving the operation of Energy Intensity Reduction CPU frequency, also can improve " overclocking " operation that mobile terminal computing power is carried out with meeting user.
As another preferable examples of the present invention, outside the mobile terminal CPU that receives input, before the value of frequency and/or frequency multiplication, described method also comprises:
Handling property to mobile terminal is monitored;
When monitoring the handling property of mobile terminal when abnormal, output information, to point out user to revise the value of the frequently outer and/or frequency multiplication of mobile terminal CPU.
Concrete can be, when the handling property (CPU usage) of mobile terminal is less than a certain threshold value, to reduce the value of the outer frequency of CPU and/or frequency multiplication with conserving mobile terminal electric energy; When the handling property (CPU usage) of mobile terminal is more than or equal to a certain threshold value, increase the value of the outer frequency of CPU and/or frequency multiplication to improve the processing power of mobile terminal.
Further, the present embodiment also comprises:
Pre-configured information, wherein:
Described information can be the display screen windows prompting under the normal state using of mobile terminal display screen, also can be the voice message under the player device normal operating conditions such as loudspeaker, can certainly be other modes, or the combination in any of these prompting modes.
For example, when monitoring the handling property of mobile terminal when abnormal, read pre-configured information, wherein, the information showing on mobile terminal display screen can be " current your terminal processes poor-performing, can suitably improve CPU frequency ".Further, this information can also comprise the numerical value that suggestion improves, for example, advise CPU frequency to improve 20MHz.
As an alternative embodiment of the invention, before carrying out above-described embodiment, can also comprise the option setting to the monitoring of mobile terminal handling property, for example, in the setting options of mobile terminal, set in advance an option, the attributes section hurdle that this function is opened or closed, only, when user opens this function, just monitors the handling property of mobile terminal.
In addition, the present embodiment starts the order that mobile terminal handling property detects and can also be preferably: be at 2 and touch and after sliding trace is longitudinal relative sliding monitoring the touch action of user on mobile terminal, whether the speed whether the range difference whether displacement that judge the two longitudinal relative slidings in touch point is greater than default first threshold, the described two final drop points in touch point is simultaneously less than default Second Threshold and described two touch points slips is greater than the 3rd default threshold value simultaneously; Or be that 2 touches and described sliding trace are after reverse direction slides monitoring described touch action, judge whether range difference that whether displacement that two touch point reverse directions slide is greater than default first threshold, the described two final drop points in touch point is simultaneously greater than the speed of the 4th default threshold value and described two touch points sliding and whether is greater than the 3rd default threshold value simultaneously, if (being that above-mentioned three condition judgment results are all "Yes"), is judged to be to start the sense command of mobile terminal handling property; (judged result of above-mentioned three conditions has one at least for "No"), does not carry out if not, finishes current operation.
In step S102, obtain the configuration file of storing the outer frequency of CPU and frequency multiplication in mobile terminal.
Concrete can be, for example, according to file suffixes name (.conf), search configuration file, and read one by one described configuration file, in the configuration file that judgement is read, whether there is character string frequently outer with described CPU and that frequency multiplication is mated, if exist, determine that this configuration file is the configuration file of the outer frequency of storage CPU and frequency multiplication, obtains this configuration file.
In step S103, value CPU in described configuration file is frequently outer and/or frequency multiplication is revised as the value of described input, and preserves amended configuration file.
For example, user inputs outer frequency 400MHz, and frequency multiplication is 3, CPU configuration file China and foreign countries value is frequently revised as to 400MHz, and the value of frequency multiplication is revised as 3, has revised rear preservation and has exited.
In step S104, mobile terminal CPU, when next clock period operation, read the value of the frequently outer and frequency multiplication of CPU in described amended configuration file, and the value of and frequency multiplication frequently outer according to the described CPU reading is moved.
Concrete, mobile terminal operating system, when operation, first reads the value of the frequently outer and frequency multiplication of CPU in described configuration file, the value of the value acquisition CPU frequency of and frequency multiplication frequently outer according to the described CPU reading, and the value operation work based on this CPU frequency.
By the embodiment of the present invention, make mobile terminal possess CPU frequency regulatory function, can facilitate user to regulate according to the actual requirements CPU frequency frequency.
