Clearly understand for making the object, technical solutions and advantages of the present invention, below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Embodiment 1
Cpu frequency control method embodiment 1 of the present invention is applied to electronic equipment, described electronic equipment can run one or more application program and described electronic equipment has processor, in this embodiment 1, when described electronic equipment detects described one or more application program generation running status change, obtain and change corresponding running state parameter with described running status; Based on the corresponding relation data prestored, mate processor frequencies information corresponding to described running state parameter (such as cpu frequency ideal value), and the frequency of operation of processor is adjusted.
Particularly, in this embodiment 1, running status changes and is presented as that one or more application program brings into operation, exits or suspends, and as shown in Figure 1, the method comprises:
Step 101: whether detection application program occurs brings into operation, exits or suspend, and obtains testing result;
Generation application program brings into operation, exits or suspends and namely there occurs operation conditions change, for this electronic equipment of mobile phone, is exemplified below:
Example 1: after user's start, bring into operation game application, thinks that operation conditions changes;
Example 2: current when running certain game application, receive phone, now telephony application brings into operation, and according to Operation system setting, such as only has operation application program, then game application is suspended, and is now operation conditions and changes;
Example 3: based on example 2, if telephone communication terminates, according to Operation system setting, game application restarts, then think and new operation conditions change occurs.
Example 4: the application program first running music, user brings into operation again certain game application, then now there occurs operation conditions change.
Step 102: when testing result shows operation conditions change occurs, obtain and change corresponding running state parameter with described running status;
Step 103: based on the corresponding relation data prestored, mates the processor frequencies information that described running state parameter is corresponding;
In corresponding relation data, the cpu frequency ideal value corresponding with the one or more application programs run can be system default, also can according to ruuning situation statistics in early stage.
When electronic equipment has multiple processor (CPU), one group of corresponding relation data comprises the processor frequencies information of described multiple processor, and the CPU running certain application program can be system configuration or dynamic assignment, below illustrates:
Example 4, electronic equipment has 2 CPU, the then application program of Operation system setting or dynamic assignment and the relation of the CPU of this application program of execution, wherein, first CPU runs application 1,2,3, second CPU runs application 4,5, then in corresponding relation, the cpu frequency ideal value of application program 1 correspondence is then the frequency of first CPU, the cpu frequency ideal value of application program 5 correspondence is then the frequency of second CPU, and the cpu frequency ideal value of application program 1 and 4 correspondence then comprises the ideal value of first cpu frequency and the ideal value of second cpu frequency.

Step 104: the frequency of operation adjusting described processor based on described processor frequencies information.
The frequency of operation of CPU is exactly the clock frequency of CPU, and the abbreviation of the frequency (the synchronizing pulse number occurred in 1 second) of work when being briefly CPU computing, unit is hertz (Hz).It determines the travelling speed of computing machine, and along with the development of computing machine, dominant frequency has developed into present GHZ(1GHZ=1000MHZ=1000000KHZ=1000000000HZ by past MHZ).Generally, the higher speed just representing computing machine of dominant frequency is also faster.
Outer frequency is the reference frequency of CPU, and unit is also MHz.Outer frequency is the speed of synchronous operation between CPU and mainboard, and current most computer system China and foreign countries are also the speed of the synchronous operation between internal memory and mainboard frequently, in this manner, the outer frequency that can be understood as CPU is directly connected with internal memory, realizes synchronous operation state between the two; The multiple of frequency multiplication and dominant frequency and the ratio of outer frequency.Dominant frequency, outer frequency, frequency multiplication, its relational expression: dominant frequency=outer frequency × frequency multiplication.
Particularly, the setting means by jumper settings and DIP switch changes CPU frequency multiplication or frequently outer.
Above example 4 when, when the application program of the current operation of electronic equipment is application program 1 and 4, need the frequency of adjustment the one CPU and the frequency of the 2nd CPU.
In the embodiment of the present invention 1, the corresponding relation of cpu frequency ideal value when saving one or more application program in advance and run, when detect occur application program bring into operation, exit or the change of the ruuning situation such as time-out time, only need the corresponding relation according to storing, the cpu frequency ideal value of mating one or more application programs of current operation corresponding can carry out rapid adjustment to cpu frequency, CPU is made to reach stable point fast, instead of dynamically slowly adjust, make system can reach the state of best performance fast, improve the experience of user.
And the corresponding relation of above-mentioned storage, be the corresponding relation of application program and handling rate frequency optimum value when running prestored in systems in which, this corresponding relation is cured in the firmware of electronic equipment to read when needing.For example, the optimum operation processor frequencies of " Sina's microblogging " application program stored in firmware is 900MHz, when " Sina's microblogging " application program is activated, electronic equipment control processor controls Sina's microblogging with the processor frequencies of 900MHz " application program launching, instead of adjust to 900MHz gradually by 200MHz.
Adopt this processor frequencies Adjusted Option, the benefit of easily seeing has: 1, can open application program fast, and without the need to waiting for the raising frequency process of processor; 2, stable processor frequencies, compared with the processor frequencies of constantly change, obviously can reduce power consumption.
