Fig. 2 is the process flow diagram of the another kind of EMS memory management process according to an exemplary embodiment, and the method is used in electronic equipment, and as shown in Figure 2, the method comprises the following steps.
In step 201, the memory headroom of this electronic equipment is divided into physical memory and virtual memory.
The memory headroom of the electronic equipments such as mobile phone is smaller; often there will be the lower data of frequency of utilization occupy memory headroom and cause the phenomenon of low memory; and in order to releasing memory space; ensure the Appropriate application of memory headroom; improve the service efficiency to memory headroom entirety; the memory headroom of this electronic equipment can be divided physical memory and virtual memory; and by unloading after data compression lower for frequency of utilization in physical memory in virtual memory, thus a part of memory headroom can be discharged by data compression.
Wherein, when the memory headroom of this electronic equipment is divided into physical memory and virtual memory, general virtual memory can be greater than physical memory, certainly, also physical memory can be less than or equal to, in practical application, can divide physical memory and virtual memory according to the actual requirements, disclosure embodiment is not specifically limited this.
It should be noted that, can with reference to correlation technique by unloading after data compression lower for frequency of utilization in physical memory to the method for virtual memory, disclosure embodiment repeats no more this.
Such as, the memory headroom of this electronic equipment is 600M, this memory headroom is divided into the physical memory of 250M and the virtual memory of 350M, the unpressed data of 250M can be stored in this physical memory, and the data after 350M compression can be stored in this virtual memory.
In step 202., the first threshold of this physical memory and the Second Threshold of this virtual memory are set.
After the physical memory of electronic equipment or virtual memory are used up, again the memory headroom of this electronic equipment is managed, may the operation of application program be caused to make mistakes because of physical memory or Insufficient virtual memory, therefore, after this electronic equipment divides physical memory and virtual memory, need to arrange the first threshold of this physical memory and the Second Threshold of this virtual memory, can know that physical memory is about to deficiency in advance by first threshold, and also can know that virtual memory is about to deficiency in advance by Second Threshold.That is to say, when remaining physical memory is less than or equal to this first threshold, namely illustrates that the physical memory of this electronic equipment is not enough, when remaining virtual memory is less than or equal to this Second Threshold, namely the Insufficient virtual memory of this electronic equipment is described.
Wherein, this first threshold and Second Threshold can be arrange when dividing physical memory and virtual memory, also can be arrange after division physical memory and virtual memory, as long as first threshold and Second Threshold carried out arranging before memory management, disclosure embodiment is not specifically limited the opportunity that arranges to first threshold and Second Threshold.
It should be noted that, this first threshold and Second Threshold can be that this electronic equipment normally runs required minimal physical internal memory and virtual memory when not installing any application program.
When the memory headroom of this electronic equipment is divided into physical memory and virtual memory, and after being provided with first threshold and Second Threshold, need the behaviour in service of monitoring this electronic equipment, determine that this electronic equipment is physical memory deficiency or Insufficient virtual memory, thus memory headroom is managed, as described below.
In step 203, physical memory and the virtual memory of electronic equipment is monitored.
Because the service condition moment of physical memory in electronic equipment and virtual memory is all changing, therefore, in order to can at physical memory during not enough or Insufficient virtual memory, this memory management parameter is adjusted in time, need physical memory and the virtual memory of this electronic equipment of Real-Time Monitoring, thus determine the first free memory of physical memory and the second free memory of virtual memory in real time.
Wherein, when monitoring physical memory and the virtual memory of this electronic equipment, not only can monitor the first free memory of physical memory and the second free memory of virtual memory, the application program that the space taking physical memory exceedes this specified memory can also be monitored, or the application program that monitoring running frequency is lower, disclosure embodiment is not specifically limited this.
It should be noted that, specified memory can be arranged in advance, and such as, specified memory is 100M, and disclosure embodiment is not specifically limited this.
In step 204, when the first free memory of this physical memory is greater than first threshold and the second free memory of this virtual memory is less than or equal to Second Threshold, increase this memory management parameter, based on the memory management parameter after increase, this physical memory and virtual memory are managed, to increase the use of physical memory and to reduce the use of virtual memory, this memory management parameter comprises specifies usage ratio or specified memory.
When the first free memory of this physical memory is greater than first threshold and the second free memory of this virtual memory is less than or equal to Second Threshold, namely the Insufficient virtual memory of this electronic equipment is described, and physical memory is sufficient, now can increase this memory management parameter, and based on the memory management parameter after increase, this physical memory and virtual memory are managed, to increase the use of physical memory and to reduce the use of virtual memory.
Wherein, the operation increasing this memory management parameter can be: when this memory management parameter comprises appointment usage ratio, can increase this appointment usage ratio; And when this memory management parameter comprises specified memory, this specified memory can be increased.
It should be noted that, this appointment usage ratio is for characterizing the ratio using memory size shared in total memory size of this physical memory of this physical memory, this specified memory is for characterizing the memory size needed for the application program of accessing this physical memory, and this appointment usage ratio and this specified memory can be pre-set according to personal habits by user, disclosure embodiment does not do concrete restriction to this.
Also it should be noted that, when increasing this memory management parameter, the first free memory that this electronic equipment often can monitor this physical memory be greater than first threshold and the second free memory of this virtual memory is less than or equal to Second Threshold time, this memory management parameter is increased fixed numbers, this fixed numbers can be preset by user, also can be preset by this electronic equipment; Certainly, the first free memory that this electronic equipment often can also monitor this physical memory be greater than first threshold and the second free memory of this virtual memory is less than or equal to Second Threshold time, be set by the user this memory management parameter, to increase this memory management parameter.
Wherein, presetting by user or this electronic equipment the fixed numbers that this memory management parameter increases at every turn, this electronic equipment can being made more steady when adjusting physical memory and virtual memory, and the first free memory often monitoring this physical memory is greater than first threshold and the second free memory of this virtual memory is less than or equal to Second Threshold time, be set by the user this memory management parameter, this electronic equipment can be made rapider when adjusting physical memory and virtual memory, but when user sets the memory management parameter of mistake, such as, this appointment usage ratio is set as the numerical value beyond 0-100% by user, or this specified memory is set as the value exceeding this electronic equipment physical memory by user, at this moment possibly cannot play the use increasing physical memory and reduce the effect that virtual memory is used, even this electronic equipment may run and make mistakes, therefore, in practical application, can arrange for different demands.
