Time device 130 then whether be conditioned according to operating frequency and start or close, and control monitoring modular 110
The detection time.Additionally, be also configured with memorizer in above-mentioned system 10, memorizer can be to set
Put at one of intrasystem separate unit or the composition assembly belonging to adjustment module 120, and in storage
In device, storage has the operating frequency of processor 210 and the matching relationship of load factor, namely processor 210
Under the use state of different loads rate, the preferred operating frequency that can use, thus having concurrently efficiently
Can be with energy-conservation mode.Wherein, the matching relationship of operating frequency and load factor can be but not
It is confined to: the load factor of operating frequency correspondence less than 10% of 37.5%, the operating frequency of 62.5% are corresponding
The load factor of 10-40%, the load factor of operating frequency correspondence 41-60% of 75%, the operating frequency of 87.5%
The load factor of corresponding 61-80% and the load factor etc. of operating frequency correspondence 81-100% of 100%.
Therefore, when the load factor measured by monitoring modular 110 be 61-80%, operating frequency be 75% time,

The operating frequency of device 210 quickly regulates to the state matched with load factor, avoids application program long
Time occurs that Caton phenomenon or energy consumption cross the generation of the problems such as height.
With some embodiments, the realization of the application method is described further below.As in figure 2 it is shown, be
The flow chart of the application first method embodiment, comprises the following steps:
Step S100, operating frequency that measurement processor is current and load factor；
According to load factor, step S110, judges whether operating frequency mates, if so, maintenance work frequency

Step S170, after intervalometer reached for the 3rd scheduled time, detects and judged for the 3rd scheduled time
After load factor whether be matched with the 3rd operating frequency；
Step S171, if so, maintains the 3rd operating frequency, and timeing closing device.
Refer to Fig. 1 and Fig. 2, the dynamically regulation processor work disclosed by the application first method embodiment
The method of working frequency comprises the following steps: first, current by monitoring module 110 measurement processor 210
Operating frequency and load factor (step S100), wherein the operating frequency of processor 210 and load factor are in just
Relevant, say, that operating frequency can raise along with the rising of load factor, and along with load factor
Decline and reduce.It is said that in general, paint when processor 210 performs word processing, network browsing or other 2D
During the application program of the low-load rates such as figure, it is only necessary to run with relatively low operating frequency and can meet use
Demand.On the contrary, when processor 210 performs 3D drawing, video code conversion, decompression or Games Software
During the application program of contour load factor, then operating frequency must be greatly improved and could meet under high load condition
Use demand.Therefore, between operating frequency and the load factor of processor 210, there is corresponding relation,
It is to say, according to load factor or the difference of load factor scope, processor 210 can be respectively with corresponding work
Working frequency operates, thus provides suitable operating frequency under different load factors, makes processor
Overall energy consumption during 210 operation reduces.
Then, after obtaining the current operating frequency of processor 210 and load factor, monitoring modular 110 will
Testing result is sent to adjustment module 120, and passes through the operating frequency that adjustment module 120 comparison is current
Whether be adapted to current load factor, then according to load factor judge operating frequency the need of regulation, its
In, if current operating frequency meets the use demand of load factor, adjustment module 120 i.e. judges work frequency
Rate is adapted to load factor and is adjusted without to operating frequency, namely maintains current operating frequency
Constant；If on the contrary, adjustment module 120 judges that operating frequency needs regulation, i.e. representing that load factor is relative
Too high or too low in operating frequency, thus perform to regulate the step (step S110) of operating frequency.
Wherein, for the regulative mode of operating frequency, it is that the height according to load factor is corresponding by operating frequency
Regulate to the first operating frequency, that is, in the case of load factor versus operating frequency is too high, represents and work as
Before operating frequency cannot meet use demand, can cause application program produce Caton phenomenon, therefore, must
Operating frequency need to be heightened to the first operating frequency, such as, operating frequency be heightened at least 50% as
One operating frequency, to guarantee fluency when application program runs；Or relatively work frequently in load factor
In the case of rate is too low, the operating frequency representing current exceedes use demand, causes the energy that processor produces
Source is not efficiently used and causes loss, therefore, by operating frequency being turned down (such as by work frequency
Rate halves) to the mode of the first operating frequency to reduce energy consumption.Further, in adjustment module 120 to work
After frequency is adjusted, starts intervalometer 130 simultaneously and calculate first scheduled time (step S120), such as
10ms (microsecond), the scheduled time of 15ms or 20ms, allow monitoring modular 110 for processor 210
Operating frequency obtains buffering with the detection process of load factor, and allows the operating frequency after regulating reach stable
After, then detect, to guarantee the accuracy of testing result.
Then, after first scheduled time, by the load factor of monitoring modular 110 measurement processor 210
The most too high relative to the first operating frequency (step S130), if so, represents that previous adjustment module 120 is right
Regulation in operating frequency also cannot meet demand, or within first scheduled time, processor 210
Load factor raise along with the running status of application program, now, adjustment module 120 by first work
Frequency is heightened to the second operating frequency, wherein the second operating frequency equal to or more than with first scheduled time after
The corresponding operating frequency of load factor, namely the first operating frequency is heightened and at least conforms to present load
The corresponding operating frequency of rate, such as, significantly heighten 50% as the second operating frequency using the first operating frequency,
Or the maximum operating frequency directly heightened to processor 120, and using maximum operating frequency as
Two operating frequencies, then start intervalometer 130 and calculate second scheduled time (step S140).Second makes a reservation for
Time equal to or more than first scheduled time, be in the present embodiment with second scheduled time be first make a reservation for
As an example, such as second scheduled time was the twice of first scheduled time to the multiple of time, the most just
Being when first scheduled time was 20ms, second scheduled time was arranged to 40ms, allowed processor at this
First run a period of time with the second operating frequency in buffer time, whether detect this operating frequency the most again
Meet use demand.
Afterwards, after terminating when the timing of second scheduled time, processed by monitoring modular 110 detection again
The load factor of device 210, and judge (the step the most too low relative to the second operating frequency of load factor now
Rapid S150), if so, represent that operating frequency, in previous regulating step, is adjusted by adjustment module 120
The highest and exceed use demand, then, in order to reduce the energy consumption of processor 210, pass through in this step
Second operating frequency is halved to the 3rd operating frequency by adjustment module 120, such as, if the second operating frequency
For 1GHz (gigahertz (GHZ)), then halved as 500MHz (megahertz) as the 3rd operating frequency, and started
Intervalometer 130 calculated for the 3rd scheduled time (step S160).Owing to the operating frequency of processor 210 is logical
Overregulate module 120 to be adjusted, therefore at warp in the way of increasing at least 50% every time or reducing 50%
After regulation several times, the operating frequency of processor 210 the most quite approaches corresponding with present load rate
Optimization frequency, and the load factor of processor 210 is probably and changes at any time, is then prolonged the detection time
Long determine whether the 3rd operating frequency meets use demand, therefore, the 3rd scheduled time can be but also
It is not limited to the multiple of second scheduled time, such as using the twice (i.e. 80ms) of second scheduled time as
Three scheduled times (step S160).
Similarly, after the 3rd scheduled time, after detecting for the 3rd scheduled time by monitoring modular 110
Whether load factor is matched with the 3rd operating frequency (step S170)；If so, the work of processor 210 is represented
In frequency has been adjusted to meet the frequency range of present load rate or frequency values, therefore maintain the 3rd work
Working frequency is constant, and timeing closing device 130 (step S171)；Otherwise, if it is not, represent the 3rd work
Frequency exceedes use demand, easily causes processor 210 and produces unnecessary energy consumption；Or it is pre-the 3rd
In fixing time, along with the change of load factor, cause the 3rd operating frequency cannot meet use demand and need
It is adjusted, now, in above-mentioned step, it is also possible to include repeating above-mentioned measurement processor
210 operating frequencies and the step (step S172) of load factor, and judge and regulation work according to load factor
The steps such as frequency, regulate the work of processor 210 repeatedly by being significantly increased or reducing every time by the way of 50%
Working frequency, until the operating frequency of processor 210 is matched with load factor.
The method dynamically regulating processor working frequency disclosed by the application, in the load factor phase of processor
For operating frequency too high or too low time, by operating frequency is significantly heightened or is turned down the side of 50% every time
Formula, can be with the range of accommodation of rapid drop operating frequency, it is thus possible to operating frequency is quickly adjusted to symbol
Before being fated, the optimum of load factor or optimum range, not only shorten the regulating time of operating frequency, moreover it is possible to
Allow processor run with corresponding energy consumption according to the height of load factor, thus reduce the entirety of processor
Energy consumption, and make the overall efficiency of processor obtain lifting.
As it is shown on figure 3, be the flow chart of the application second method embodiment.Disclosed by the application second
Embodiment of the method and first method embodiment are for substantially phase on the regulative mode of the operating frequency of processor
With, difference between the two is, after intervalometer reached for first scheduled time, detects and judges that first is pre-
In the operation that load factor after fixing time is the most too high relative to the first operating frequency (step S230), if first
Load factor after the scheduled time is the most too high relative to the first operating frequency, then carry out following operation:
Step S240, it is judged that the load factor after first scheduled time is the most too low relative to the first operating frequency；
Step S250, if it is not, maintain the first operating frequency constant；And
If so, following steps are performed:
Step S260, halves the first operating frequency to the 4th operating frequency, and starts intervalometer and open
Beginning timing；
Step S270, after intervalometer reached for second scheduled time, detects and judged for second scheduled time
After load factor the most too low relative to the 4th operating frequency；
Step S280, if so, halves the 4th operating frequency to the 5th operating frequency, and startup is fixed
Time device start timing；And
Step S290, after intervalometer reached for the 3rd scheduled time, detects and judged for the 3rd scheduled time
After load factor whether be matched with the 5th operating frequency；
Step S291, if so, maintains the 5th operating frequency, and timeing closing device.
Refer to Fig. 1 and Fig. 3, in the second method embodiment disclosed by the application, when processor 210
Job step rate be adjusted to the first operating frequency, and after first scheduled time, monitoring modular
110 first to detect the load factor after first scheduled time the most too high relative to the first operating frequency, if so, holds
Row the first operating frequency is heightened to the second operating frequency, and starts intervalometer and calculated for second scheduled time
Step and as described in the first embodiment corresponding steps.If it is not, then determine whether the first pre-timing
Load factor after between the most too low relative to the first operating frequency (step S240), if it is not, represent the first work
Frequency is applicable to load factor now, therefore maintains same frequency not to be adjusted (step S250)；Instead
It, if so, represent that the first operating frequency can not only meet the use demand of present load rate, super
Go out use demand, therefore, in order to reduce the energy consumption of processor 210, further by the first work frequency
Rate halves to the 4th operating frequency (step S260), and starts intervalometer and calculated for second scheduled time.So
After, after second scheduled time, detect the load factor after second scheduled time relative to the 4th operating frequency
The most too low (step S270), if so, represents that the 4th operating frequency is the highest, therefore works the 4th
Frequency halving is to the 5th operating frequency, and starts intervalometer the 3rd scheduled time (step S280) of calculating.
Then, similarly, after the 3rd scheduled time, after detecting for the 3rd scheduled time by monitoring modular 110
Load factor whether be matched with the 5th operating frequency step (S290), and perform maintenance according to testing result
5th operating frequency, and the operation (step S291) of timeing closing device；Or, repeat above-mentioned
Measurement processor 210 operating frequency judges and regulation operating frequency etc. with load factor and according to load factor
Etc. step, till the operating frequency of processor 210 is matched with load factor (step S292).
As shown in Figure 4, for the flow chart of the application third method embodiment.Disclosed by the application the 3rd
Embodiment of the method is with the difference of first method embodiment, after second scheduled time, if second makes a reservation for
Whether the testing result of the load factor after the time the most too low relative to the second operating frequency (step S350)
Fixed, then the following operation of execution:
Step S360, it is judged that the load factor after second scheduled time is the most too high relative to the second operating frequency；
Step S370, if it is not, maintain the second operating frequency constant；And
If so, following steps are performed:
Step S380, heightens the second operating frequency to the 6th operating frequency, and starts intervalometer and open
Beginning timing；
Step S390, after intervalometer reached for the 3rd scheduled time, detects and judged for the 3rd scheduled time
After load factor whether be matched with the 6th operating frequency；
Step S391, if so, maintains the 6th operating frequency, and closes described intervalometer.
Refer to Fig. 1 and Fig. 4, the third method embodiment disclosed by the application is according to load factor equally
With the comparison result of operating frequency, in the way of at least heightening 50% or turning down 50%, work frequency by second
Rate regulation is to equaling to or more than and the corresponding operating frequency of load factor after described second scheduled time, to make
It is the 6th operating frequency, and by this regulative mode repeatedly halved and double, allows operating frequency exist
After regulation several times, just can approach frequency values or the frequency range being adapted to present load rate.Additionally,
If it is understood that during the regulation that the second operating frequency is the most previously, being raised processor
210 maximum operating frequency time, then in above-mentioned steps S380, owing to reaching processor 210 institute
The maximum being provided that, therefore directly using the maximum operating frequency of processor 210 as the 6th work frequency
