Refer to Fig. 1, Fig. 1 is the schematic flow sheet of a kind of DDR control method disclosed in the embodiment of the present invention.Wherein, method shown in Fig. 1 can be applied to smart mobile phone (as Android phone, iOS mobile phone etc.), panel computer, palm PC, personal digital assistant (PersonalDigitalAssistant, PDA), the mobile terminal such as mobile internet device (MobileInternetDevice, MID) and Intelligent worn device.As shown in Figure 1, this DDR control method can comprise the following steps:
S101, mobile terminal determine the application type of the application program of current operation.
In the embodiment of the present invention, DDR is writing a Chinese character in simplified form of DDRSDRAM, is DoubleDataRateSynchronousDynamicRandomAccessMemory, Double Data Rate synchronous DRAM.Mobile terminal includes main DDR and auxiliary DDR, and wherein the quantity of auxiliary DDR can be one, and also can be multiple, the embodiment of the present invention mainly carries out expansion explanation with the mobile terminal comprising an auxiliary DDR.In the mobile terminal comprising main DDR and auxiliary DDR, main DDR is mainly used in the data produced when buffer memory mobile terminal operating system runs, and therefore, main DDR will start when mobile terminal is opened, and under normal circumstances, auxiliary DDR acquiescence is in closed condition.It should be noted that, the capacity of main DDR can be less than the capacity of auxiliary DDR, also can be greater than the capacity of auxiliary DDR, can also be equal with the capacity of auxiliary DDR, and the embodiment of the present invention does not limit.
In the embodiment of the present invention, when user opens a certain application program, mobile terminal will determine the application type of this application program.Wherein, application type can beautify class including but not limited to audio-visual amusement class, working and studying class, convenient life kind, trip navigation type, social communication class, utility class and shooting.
Optionally, mobile terminal can be the application type needing to determine this application program when running each application program, also can be that just determine the application type of this application program, the embodiment of the present invention does not limit only when running the application program of non-OS type.Wherein, the application program that the operating system that the application program of OS Type refers to mobile terminal carries, as the application program that the users such as clock, counter, mirror, calendar and p.m.entry can not manually unload, so non-OS type application program and be user downloads and installs from internet except this kind of application application.
S102, mobile terminal judge whether this application type is default application type, if so, perform step S103; If not, process ends.
In the embodiment of the present invention, mobile terminal, after determining the application type of this application program, can judge whether this application type is default application type further.This default application type can be user-defined, and also can be that mobile terminal is arranged, the embodiment of the present invention limit.
Wherein, this default application type can for needing jumbo DDR to carry out the application of data buffer storage when audio-visual amusement class etc. is run, and the application of audio-visual amusement class can comprise game class application, the application of video playback class, the application of music class, the embodiment of the present invention does not limit.
Therefore, when judging the application type of this application program for presetting application type, under the state that mobile terminal will be opened at main DDR, auxiliary DDR is started.And when judging the application type of this application program not for presetting application type, the data buffer storage produced when this application program can directly be run by mobile terminal is to main DDR.
S103, mobile terminal start auxiliary DDR, and the data buffer storage produced when this application program being run is to auxiliary DDR, and process ends.
In the embodiment of the present invention, when judging the application type of this application program for presetting application type, mobile terminal can start auxiliary DDR, and the data buffer storage produced when then this application program being run is to this auxiliary DDR.
In specific implementation, the concrete mode that mobile terminal starts auxiliary DDR can be: provide electric energy to auxiliary DDR, namely starts each storage unit in auxiliary DDR and refreshes, thus make auxiliary DDR in running order.
Optionally, whether mobile terminal when judging the application type of this application program for presetting application type, can also be connected with mobile network, and using this mobile network when determining that this application program is run further.If so, auxiliary DDR is just started; And if not, then the data buffer storage produced when can directly this application program be run to main DDR, and does not start auxiliary DDR.Such as, when mobile terminal detects that user is using a certain application program to watch video online, the data volume of the buffer memory that so may need is comparatively large, therefore, mobile terminal just can directly start auxiliary DDR, thus by the video data buffer memory of this application program to auxiliary DDR.And for example, when mobile terminal detects the music that user using a certain application program to play in local folders, so auxiliary DDR would not be started.
For example, when user plays mobile phone network game on mobile phone, mobile phone just can determine that the application type of the current application program used is audio-visual amusement class, so just can while providing electric energy to main DDR, there is provided electric energy also to auxiliary DDR, make auxiliary DDR in running order, so mobile terminal is when running this application program, in the data buffer storage that just this application program can be produced to auxiliary DDR.
Visible, in the method described by Fig. 1, mobile terminal comprises main DDR and auxiliary DDR, when detecting that current operation has a certain application program, mobile terminal can determine the application type of this application program, and judges whether this application type is default application type, if, just start auxiliary DDR, and the data buffer storage produced when this application program being run is to auxiliary DDR.By in the embodiment of the present invention, mobile terminal is provided with two DDR, if the application program of current operation belongs to the application of audio-visual amusement class, mobile terminal just can start auxiliary DDR, the fluency of mobile terminal when running this kind of application program can being ensured like this, promoting Consumer's Experience.
Refer to Fig. 2, Fig. 2 is the schematic flow sheet of another kind of DDR control method disclosed in the embodiment of the present invention.Wherein, the method shown in Fig. 2 can be applied to the mobile terminal such as smart mobile phone (as Android phone, iOS mobile phone etc.), panel computer, palm PC, personal digital assistant, mobile internet device and Intelligent worn device.As shown in Figure 2, this DDR control method can comprise the following steps:
S201, mobile terminal determine the application type of the application program of current operation.
S202, mobile terminal judge whether this application type is default application type, if so, perform step S203; If not, step S204 ~ step S208 is performed.
In the embodiment of the present invention, when judging the application type of this application program for presetting application type, under the state that mobile terminal will be opened at main DDR, start auxiliary DDR.And when judging the application type of this application program not for presetting application type, mobile terminal can obtain first residual capacity of main DDR.
S203, mobile terminal start auxiliary DDR, and the data buffer storage produced when this application program being run is to auxiliary DDR.
First residual capacity of the main DDR of S204, acquisition for mobile terminal, and obtain the maximum data buffer memory produced when this pre-recorded application program is run.
In the embodiment of the present invention, for each application program, mobile terminal can be recorded in the historical data buffer memory of this application program when each run in preset time period, also can be recorded in the historical data buffer memory of this application program when each run in default number of run.Wherein, this preset time period can be one week, also can be several days, and to preset number of run can be 10 times, and also can be 5 inferior, the embodiment of the present invention limit.This first residual capacity is mobile terminal and is just starting this application program, and when judging the application type of this application program not for presetting application type, the residual capacity that main DDR is current.
For example, when mobile terminal is provided with application A, application program B and application program C, mobile terminal can be recorded within one week, the data volume produced when application A, application program B and application program C each run, and mobile terminal can upgrade data volume during each application program each run every day.
Therefore, mobile terminal is while the first residual capacity obtaining main DDR, can also from the data buffer storage amount of each pre-recorded application program, obtain the maximum data buffer memory of this application program, so that before the data buffer storage produced when this application program being run to main DDR, judge whether the residual capacity of main DDR meets maximum capacity demand when this application program is run.
Optionally, mobile terminal can not also determine whether starting auxiliary DDR according to the application type of the application program of current operation, and directly decides unlatching or the closedown of auxiliary DDR according to the residual capacity of main DDR.That is, if the data volume of buffer memory is more in main DDR, so just start auxiliary DDR, if and the data volume of buffer memory is few in main DDR, so still, continue to use main DDR to carry out data buffer storage, and auxiliary DDR keeps closed condition, in time the DDR capacity of mobile terminal can be expanded when main DDR capacity is inadequate like this, also can reduce the power consumption of DDR when capacity abundance.
S205, mobile terminal judge whether this first residual capacity is greater than this maximum data buffer memory, if so, perform step S206; If not, step S203 is performed.
In the embodiment of the present invention, mobile terminal is getting first residual capacity of main DDR, and after maximum data buffer memory when pre-recorded this application program is run, can compare this first residual capacity and this maximum data buffer memory further.If this first residual capacity is greater than this maximum data buffer memory, the data buffer storage produced when so this application program will be run by mobile terminal is to main DDR; And if this first residual capacity is less than or equal to this maximum data buffer memory, so mobile terminal just can start auxiliary DDR, and the data buffer storage produced when this application program being run is to auxiliary DDR.
As a kind of feasible embodiment, when mobile terminal judges that this first residual capacity is less than or equal to this maximum data buffer memory, mobile terminal can also perform following steps:
Step 11) data buffer storage that produces when this application program being run of mobile terminal to main DDR, and detects second residual capacity of this main DDR;
Step 12) when this second residual capacity is less than preset capacity threshold value, start auxiliary DDR, and this application program is run the data buffer storage of stylish generation to auxiliary DDR.
In specific implementation, mobile terminal is when judging that first residual capacity of main DDR is less than or equal to the maximum data buffer memory of this application program, the data buffer storage produced when this application program can also first be run by mobile terminal is to main DDR, then in this application program operational process, the residual capacity of this main DDR of real-time detection, i.e. the second residual capacity, and judge whether this second residual capacity is less than preset capacity threshold value, if be less than, just start and power to auxiliary DDR, and the data buffer storage this application program being run stylish generation is to auxiliary DDR.
It should be noted that, this preset capacity threshold value can be a less capability value, and can be also 0, the embodiment of the present invention limit.When preset capacity threshold value is a less capability value, be understandable that, mobile terminal is carrying out starting in the process of auxiliary DDR, can ensure that the residual capacity of main DDR can meet the demand of the data buffer storage amount of this application program in auxiliary DDR section start-up time.
Be understandable that, mobile terminal is after the auxiliary DDR of startup, the data buffer storage this application program being run stylish generation can be understood as to auxiliary DDR: mobile terminal be the data buffer storage that will produce when this application program is run after auxiliary DDR starts to auxiliary DDR, and the data that auxiliary DDR produces before starting still are buffered in main DDR.Can just start auxiliary DDR when the capacity of main DDR is inadequate in this way, the power consumption of DDR can be reduced so to a certain extent.
S206, mobile terminal control auxiliary DDR and keep closed condition, and the data buffer storage produced when this application program being run is to main DDR.
In the embodiment of the present invention, when judging that the first residual capacity is greater than the maximum data buffer memory of this application program, mobile terminal can control auxiliary DDR and keep closed condition, and the data buffer storage produced when this application program being run is to main DDR.When the capacity of main DDR is enough, only can starts main DDR, the power consumption of DDR in mobile terminal can be reduced like this.
As a kind of feasible embodiment, no matter be the auxiliary DDR that default application type starts at the application type of the application program judging current operation, or judge current operation application program application type for preset application type, but first residual capacity of this main DDR is less than the maximum data buffer memory of this pre-recorded application program and the auxiliary DDR started, or judge current operation application program application type for preset application type, but first residual capacity of this main DDR is less than the maximum data buffer memory of this pre-recorded application program, and the auxiliary DDR started when second residual capacity of main DDR is less than preset capacity threshold value, mobile terminal is after starting auxiliary DDR, following operation can also be performed:
Step 21) mobile terminal detect this application program whether terminate run;
Step 22) when detecting that this application program terminates to run, mobile terminal closes auxiliary DDR.
In specific implementation, whether this application program that detects mobile terminal terminates to run, and can be at the auxiliary DDR of startup, and the data buffer storage produced when this application program being run performs to auxiliary DDR, as long as detect that this application program terminates to run, this mobile terminal just can close auxiliary DDR.Concrete, the mode that mobile terminal closes auxiliary DDR is and stops providing electric energy to auxiliary DDR.Mobile terminal is after the auxiliary DDR of closedown, and in auxiliary DDR, the various data of buffer memory all can be cleared.
It should be noted that, mobile terminal just closes auxiliary DDR when detecting that this application program terminates operation, when the capacity of winner DDR can be enable like this to meet the schedule operation demand of mobile terminal, remain that auxiliary DDR is in closed condition, greatly reduce the power consumption of mobile terminal DDR.
Visible, in the method described by Fig. 2, mobile terminal presets the application program of application type running, or when the current residual capacity of main DDR can not meet the data buffer storage demand of the application program of current operation, start auxiliary DDR, and auxiliary DDR is closed when the residual capacity that main DDR is current can meet the data buffer storage demand of the application program of current operation, capacity extensions can be carried out neatly like this to the DDR of mobile terminal, ensure fluency during running of mobile terminal, the power consumption of DDR can also be reduced in the ordinary course of things, thus promote Consumer's Experience.
