Those skilled in the art are better understood upon the background of related of the application for convenience, and applicant is first to existing
4 kinds of CPU chirping strategies of some Android systems are simply introduced.Android system mainly has 4 kinds of CPU chirping strategies：
Performance (performance strategy), powersave (power-saving strategies), ondemand (tactful on demand), and, userspace
(User space strategy).
Wherein, " performance " represents that CPU is fixed under this policy and operates in maximum operating frequency.But so
CPU power consumption can be caused too big." powersave " represents that CPU is fixed under this policy and operates in lowest operating frequency.But
The lower CPU of this strategy performance is worst, and many situations can not meet requirement of the user to performance." ondemand " is represented this
The lower CPU of strategy operates in relatively low working frequency, and CPU working frequency can be improved when system load increases.Due to this strategy
It is that constantly loading condition of the computing system during a timer, draws after load value, according to one based on a timer
Fixed algorithm, determines whether to adjust CPU working frequency and how to adjust a bit.But because of the average value in a cycle
The frequency needs of system can not be truly reflected, especially with the result of a cycle before current time, to determine
The frequency of next cycle system, so this regulation is also inaccurate." userspace " represents that CPU works under this policy
Frequency is by User space control.This tactful the problem of is that User space is difficult the accurate frequency for knowing that how high system needs are.
With reference to Fig. 1, the flow of the control method embodiment of cpu frequency in a kind of android system of the application is shown
Figure, may comprise steps of：
Step 101：In response to startup movable in current android system, the movable corresponding history CPU frequencies are obtained
Rate value.
In the embodiment of the present application, a frequency modulation manager can be set, to monitor startup movable in android system
Or stop.If listening to activity in current android system to start, the movable history cpu frequency can be got
Value, is that once operationally corresponding cpu frequency value was how many for the activity.Specifically, it is real that a decision-making device can be set
Existing step 101 and step 102, when frequency modulation manager, which listens to activity, to be started, just call decision-making device to get activity
Corresponding history cpu frequency value.
Wherein, the step of obtaining the movable corresponding history cpu frequency value, can specifically include：
Step A1：Obtain the movable activity name.
Because each activity in android system has corresponding title, have been started up movable is got first
Activity name.
Step A2：The movable corresponding history cpu frequency value is obtained from data management system according to the activity name.
In the present embodiment, a data management system can be set to be used for depositing each movable corresponding history cpu frequency
Value, then after activity name is obtained, it is possible to which correspondence finds the history cpu frequency value of matching from data management system.
It is understood that in the embodiment of the present application, a sampler can be set, for during activity starts,
Gather CPU working frequency.So after the activity starts, in addition to：
Step B：The cpu frequency value of the activity operation is gathered according to default collection period, and by the CPU collected frequently
Rate value is stored to data management system.
In actual applications, the collection period of sampler can be pre-set, then after activity starts, it is possible to by adopting
Cpu frequency value when sample device is run according to default collection period collection activity, and by the cpu frequency value and activity name that collect
Claim correspondence to store to data management system, inquire about and obtain from data management system during so as to follow-up needing.Wherein, collection period can be with
In units of millisecond, such as hundreds of milliseconds.
Step 102：The current frequency of the CPU is controlled according to the movable corresponding history cpu frequency value.
When the movable corresponding history cpu frequency value is obtained, just control CPU's with reference to history cpu frequency value
Current frequency.
Step 102 can include when implementing：
Step C1：Judge whether the movable execution number of times meets preset times threshold value, if it is, into step C2,
If it is not, then into step C3.
In actual applications, because not having corresponding CPU historical frequencies value when there may be movable operation for the first time
Situation, it is possible to first judge whether the movable execution number of times meets preset times threshold value.For example, preset times threshold value is set
1 is set to, represents, if activity had been performed once, to be put into step C2, explanation activity has not been performed if being unsatisfactory for
Cross, be put into step C3.
Step C2：The current frequency of the CPU is determined according to the movable corresponding history cpu frequency value.
If activity had been performed once, then the history that the samplers sample that will be stored with data management system is arrived
Cpu frequency value, now may be referred to history cpu frequency value to determine CPU current frequency.
Step C3：The current frequency of the CPU is determined according to strategy on demand.
And if activity was not performed, then CPU frequency can be determined in the way of the strategy on demand introduced before
Rate, that is to say by the kernel state of android system to determine CPU current frequency.Because determining that CPU's is current by kernel state
Frequency belongs to prior art, will not be repeated here.
In actual applications, step C2 can include when implementing：
Step D1：Judge whether the movable history cpu frequency value meets frequency fluctuation threshold value, if it is, into
Step D2, if it is not, then into step D4.
It is understood that when the frequency values according to history CPU are to determine current cpu frequency, can first judge
Whether history cpu frequency value meets frequency fluctuation threshold value, and such as frequency fluctuation threshold value is 1, then illustrates that the multiple of corresponding record go through
History cpu frequency value is all equal, is only one of which frequency values, and CPU operatings are more normal when now explanation activity starts, frequency
Rate is more stable, then can enter the current frequency that history cpu frequency value is directly defined as to CPU in step D2.Certainly, frequency
Fluctuation threshold it can also be provided that 2, be it is corresponding with the activity in data management system have two history cpu frequency values, now
May determine that be some frequency values shared by ratio be more than a default proportion threshold value, such as 90%, if
In the presence of such frequency values, then the frequency values can be defined as to CPU present operating frequency, conversely, then also needing to enter step
Rapid D3, CPU present operating frequency is determined according to strategy on demand.Certainly, those skilled in the art can also be according to the actual requirements
To set other numerical value.
Step D2：Judge whether that proportion is more than the cpu frequency value of threshold percentage threshold value, if it is present entering
Enter step D3, if it does not exist, then into step D4.
In the case where meeting frequency fluctuation threshold value, the CPU for whether having proportion to be more than threshold percentage threshold value is judged
Frequency values, if so, also illustrating that CPU working frequency is relatively stablized.
Step D3：The cpu frequency value that proportion is more than preset ratio threshold value is defined as to CPU present operating frequency.
Step D4：The frequency of the CPU is determined according to strategy on demand.
If not meeting frequency fluctuation threshold value, although or meet frequency fluctuation threshold value, proportion is not present
More than the cpu frequency value of preset ratio threshold value, all illustrate that the CPU frequency fluctuation recorded in data management system is larger, then this
When just can determine CPU frequency according further to strategy on demand.
Using the embodiment of the present invention, by using the activity in system as reference, and according to movable corresponding history cpu frequency
Value controls CPU current frequency, CPU working frequency can be enable effectively to be reduced, and then can effectively reduce
The power consumption of mobile device, extends the battery durable power of mobile device, can not only so save the resource of mobile device, additionally it is possible to
Lift the usage experience of user.
