Example is applied no longer to repeat this one by one.
Fig. 2 is the flow chart of another EMS memory management process shown according to an exemplary embodiment, and this method is for electricity
In sub- equipment, as shown in Fig. 2, this approach includes the following steps.
In step 201, the memory headroom of the electronic equipment is divided into physical memory and virtual memory.
The memory headroom of the electronic equipments such as mobile phone is smaller, often will appear the lower data of frequency of use and occupies memory sky
Between and the phenomenon that lead to low memory, and for releasing memory space, ensure the reasonable utilization of memory headroom, improve to memory sky
Between whole service efficiency, the memory headroom of the electronic equipment can be divided physical memory and virtual memory, and will be in physics
It is transferred in virtual memory after depositing the lower data compression of frequency of use, to which a part can be released by data compression
Memory headroom.
Wherein, when the memory headroom of the electronic equipment being divided into physical memory and virtual memory, general virtual memory can
To be more than physical memory, it is of course also possible to be less than or equal to physical memory, in practical application, can be drawn according to actual demand
Physical memory and virtual memory, the embodiment of the present disclosure is divided to be not specifically limited this.
It should be noted that the method that virtual memory will be transferred to after the lower data compression of frequency of use in physical memory
The relevant technologies can be referred to, the embodiment of the present disclosure repeats no more this.
For example, the memory headroom of the electronic equipment be 600M, by the memory headroom be divided into 250M physical memory and
The virtual memory of 350M can store the unpressed data of 250M in the physical memory, and can be deposited in the virtual memory
Store up the compressed data of 350M.
In step 202, the first threshold of the physical memory and the second threshold of the virtual memory are set.
When the physical memory or virtual memory of electronic equipment are used up and then are carried out to the memory headroom of the electronic equipment
Management, may cause the operation of application program to malfunction, therefore, which sets because of physical memory or Insufficient virtual memory
After standby division physical memory and virtual memory, the second threshold of first threshold and the virtual memory that the physical memory is set is needed
Value, can know that physical memory i.e. will be insufficient, and can also know void in advance by second threshold in advance by first threshold
Quasi- memory i.e. will be insufficient.It that is to say, when remaining physical memory is less than or equal to the first threshold, that is, illustrate the electronic equipment
Physical memory it is insufficient, when remaining virtual memory is less than or equal to the second threshold, that is, illustrate the virtual of the electronic equipment
Low memory.
Wherein, the first threshold and second threshold can be arranged when dividing physical memory and virtual memory, can also
It is to be arranged after dividing physical memory and virtual memory, as long as first threshold and second threshold are set before memory management
It sets, the embodiment of the present disclosure is not specifically limited the setting opportunity of first threshold and second threshold.
It should be noted that the first threshold and second threshold can be the electronic equipments when not installing any application program
Minimal physical memory needed for normal operation and virtual memory.
When the memory headroom of the electronic equipment is divided into physical memory and virtual memory, and provided with first threshold and the
After two threshold values, the behaviour in service for monitoring the electronic equipment is needed, to determine that the electronic equipment is that physical memory is insufficient or empty
Quasi- low memory, to be managed to memory headroom, as described below.
In step 203, the physical memory and virtual memory of electronic equipment are monitored.
Since the service condition moment of physical memory in electronic equipment and virtual memory is all changing, in order to
In physical memory deficiency or Insufficient virtual memory, which is adjusted in time, needs to monitor in real time and be somebody's turn to do
The physical memory and virtual memory of electronic equipment, to determine in real time physical memory the first free memory and virtual memory the
Two free memories.
Wherein, when monitoring the physical memory and virtual memory of the electronic equipment, the of physical memory can not only be monitored
Second free memory of one free memory and virtual memory, it is more than the specified memory that can also monitor and occupy the space of physical memory
Application program, or the monitoring lower application program of running frequency, the embodiment of the present disclosure is not specifically limited this.
It should be noted that specified memory can be arranged in advance, for example, specified memory is 100M, the embodiment of the present disclosure pair
This is not specifically limited.
In step 204, when the first free memory of the physical memory is more than first threshold and the second of the virtual memory
When free memory is less than or equal to second threshold, increase the memory management parameter, based on the memory management parameter after increase, to this
Physical memory and virtual memory are managed, to increase the use of physical memory and reduce the use of virtual memory, the memory pipe
It includes specified use ratio or specified memory to manage parameter.
When the second free memory that the first free memory of the physical memory is more than first threshold and the virtual memory is less than
Or when equal to second threshold, that is, illustrate the Insufficient virtual memory of the electronic equipment, and physical memory is sufficient, can increase this at this time
Memory management parameter, and based on the memory management parameter after increase, the physical memory and virtual memory are managed, to increase
The use of physical memory and the use for reducing virtual memory.
Wherein, increasing the operation of the memory management parameter can be：When the memory management parameter includes specified use ratio
When, the specified use ratio can be increased；And when the memory management parameter includes specified memory, it is specified interior that this can be increased
It deposits.
It should be noted that the specified use ratio be used to characterize the physical memory used memory size in the physics
Shared ratio in total memory size of memory, the specified memory are used to characterize needed for the application program for accessing the physical memory
Memory size, and the specified use ratio and the specified memory can be pre-set by user according to personal habits, the disclosure is real
Example is applied to be not especially limited this.
It should also be noted that, when increasing the memory management parameter, which can be often to monitor the physical memory
The first free memory when being more than the second free memory of first threshold and the virtual memory and being less than or equal to second threshold, by this
Memory management parameter increases fixed numbers, which can be preset by user, can also be advance by the electronic equipment
Setting；Certainly, which can be often to monitor that the first free memory of the physical memory is more than first threshold and the void
When second free memory of quasi- memory is less than or equal to second threshold, it is set by the user the memory management parameter, it is interior to increase this
Deposit management parameters.
Wherein, the memory management parameter increased fixed numbers every time are preset by user or the electronic equipment, it can
So that the electronic equipment is more steady when adjusting physical memory and virtual memory；And often monitor that the first of the physical memory remains
When remaining memory is more than the second free memory of first threshold and the virtual memory less than or equal to second threshold, it is set by the user this
Memory management parameter can make the electronic equipment rapider when adjusting physical memory and virtual memory, but when user sets
The memory management parameter of mistake, for example, this is specified use ratio to be set as the numerical value other than 0-100% or user by user
The specified memory is set as the value more than the electronic equipment physical memory, at this moment possibly can not play and increase making for physical memory
With and reduce the effect used to virtual memory or even the electronic equipment and may run error, therefore, can be in practical application
It is configured for different demands.
It should be noted that the electronic equipment is based on the memory management parameter after increase, it is to the physical memory and virtually interior
The relevant technologies can be referred to by depositing the method being managed, this is no longer described in detail in the embodiment of the present disclosure.
In the embodiments of the present disclosure, memory management device can be electronic equipment, which may include Java layers
Strategic control module, core layer (English：Kernel) memory configurations and monitoring modular and Java local interfaces middle layer (English：
Java Native Interface；Referred to as：Jni) module.Java layers of strategic control module can be connect by Jni middle layer modules
Receive the Kernel layers of physical memory reported deficiency or the event of Insufficient virtual memory, the type by event and other policy informations
It determines to increase or reduce memory management parameter, application layer configuration management module is then informed by Jni middle layer modules.
Kernel layers of memory configurations and monitoring modular receive Java layer strategic control module can be issued in initialization first threshold with
Second threshold, when monitoring that the first free memory is less than or equal to first threshold and the second free memory is more than second threshold,
The insufficient event of physical memory is reported to Java layers of strategic control module；When the second free memory of discovery is less than or equal to second
When threshold value and the first free memory are more than first threshold, i.e., the thing of Insufficient virtual memory is reported to Java layers of strategic control module
Part.Jni middle layer modules are the programs based on C language and the interface that mutually calls and communicate between the program based on Java language
Layer, Jni middle layer modules realize Java layers of strategic control module and match with Kenerl layers of memory configurations and monitoring modular, application layer
Set the interface of management module communication.Application layer configuration management module increases memory according to the instruction of java layers of strategic control module
Management parameters reduce memory management parameter.For example, as shown in figure 3, working as Kernel layers of memory configurations and monitoring module monitors
When being more than first threshold and the second free memory to the first free memory and being less than or equal to second threshold, pass through Jni middle layer moulds
Block reports physical memory abundance to Java layers of strategic control module and Insufficient virtual memory, Java layers of strategic control module pass through
Jni middle layer modules inform that application layer configuration management module increases memory management parameter, when the memory management parameter includes specified
When use ratio, application layer configuration management module increases the specified use ratio；When the memory management parameter includes specified memory
When, increase the specified memory, to increase the use of physical memory and reduce the use of virtual memory.
For example, the electronic equipment memory headroom is physical memory 250M, virtual memory 350M, setting first threshold is 50M,
Second threshold is 70M, and current specified use ratio is 80%, specified memory 200M.When monitoring that the first free memory is
When 210M, the second free memory are 40M, i.e. the first free memory is more than first threshold and the second free memory is less than the second threshold
Value illustrates that electronic equipment physical memory is sufficient and Insufficient virtual memory, therefore specifies use ratio to be increased to by 80% this
85%, or the specified memory is increased into 230M by 200M, it can so reduce use of the electronic equipment to virtual memory
And use of the increase to physical memory.
In step 205, when the first free memory of the physical memory is less than or equal to first threshold and the virtual memory
The second free memory when being more than second threshold, reduce the memory management parameter, to reduce the use of physics and increase in virtual
The use deposited.
When first free memory is less than or equal to the first threshold and second free memory is more than the second threshold,
Illustrate that the physical memory of the electronic equipment is insufficient, and virtual memory is sufficient, at this point, the electronic equipment can reduce the memory pipe
Parameter is managed, with the use increased to virtual memory and the use reduced to physical memory.
Wherein, reducing the operation of the memory management parameter can be：When the memory management parameter includes specified use ratio
When, the specified use ratio can be reduced；And when the memory management parameter includes specified memory, it is specified interior that this can be reduced
It deposits.
It should be noted that when reducing the memory management parameter, which can be often to monitor the physical memory
It is when first free memory is less than or equal to the second free memory of first threshold and the virtual memory more than second threshold, this is interior
It deposits management parameters and reduces fixed numbers, which can be preset by user, can also in advance be set by the electronic equipment
It is fixed；Certainly, the electronic equipment can with often monitor the physical memory the first free memory be less than or equal to first threshold and
When second free memory of the virtual memory is more than second threshold, it is set by the user the memory management parameter, to reduce the memory
Management parameters.
For example, when monitoring that first free memory of electronic equipment is 30M, when the second free memory is 190M, i.e., first
Free memory is less than first threshold and the second free memory and is more than second threshold, illustrate the virtual memory of the electronic equipment it is sufficient and
Physical memory is insufficient, therefore the designated ratio is reduced to 75% by 80%, or the specified memory is reduced to 170M, so
Use of the electronic equipment to the use of virtual memory and reduction to physical memory can be increased.
In step 206, when first free memory is less than or equal to the first threshold and second free memory is less than
Or when equal to the second threshold, display reminding information, the prompt message is for prompting memory headroom insufficient.
When first free memory be less than or equal to the first threshold and second free memory be less than or equal to this second
When threshold value, that is, illustrate that the physical memory of the electronic equipment and virtual memory are all insufficient, at this point, the electronic equipment can be with display reminding
Information, to prompt the memory headroom of user's electronic equipment insufficient.
Wherein, when showing the prompt message, which can also show that it is more than in this is specified to occupy physical memory
The lower application program identification of application program identification or running frequency deposited so that user has found that certain malice occupy in time
The virus applications of memory or the very low application of certain frequency of use improve the service efficiency of memory to delete the application.
It should be noted that show the mode of the prompt message can be shown by pop-up, window is shown or other
Mode shows that it is not limited in this embodiment of the present disclosure.
In addition, application program identification is for the unique mark application program, and the application program identification can be the application
The title of program, icon etc., the embodiment of the present disclosure is not specifically limited this.
For example, when monitoring that first free memory of electronic equipment is 30M, when the second free memory is 40M, i.e., first is surplus
Remaining memory is less than first threshold and the second free memory is less than second threshold, illustrates the electronic equipment virtual memory and physical memory
Insufficient, display reminding information prompts user memory insufficient.
The embodiment of the present disclosure monitors the physics of the electronic equipment by the first threshold and second threshold of the electronic equipment
