[background technique]
The development advanced by leaps and bounds with the Internet infrastructure, while China promotes the strength of industry internet, intelligence
End product and its APP application are maked rapid progress, and in the market in the competition of similar intelligent terminal, how ultimate attainment Optimum utilization is well existing
Some intelligent terminal memories promote cost performance, are that those skilled in the art often consider the problems of.
Current situation is, in the case where hardware finite, memory is unable to get ultimate attainment utilization, causes the wave of resource
Take.
Based on this, those skilled in the art have carried out a large amount of research and development and experiment, and achieve preferable achievement.
[summary of the invention]
To overcome the problems of prior art, the present invention provides a kind of embedded intelligence that can be obviously improved cost performance

The scheme that the present invention solves technical problem is to provide a kind of embedded intelligent terminal dynamic memory optimization method, including
Following steps,
S1: setting decompresses load, the dlm (dynamic loading module) of unloading and dynamic offloading module for carrying out dynamic；
S2: creation m_module_1 and m_module_2；It determines two and two or more will not use (mutual exclusion) with the time
Function or application program, its respective .a (.o) is configured in the m_module_1 and m_module_2 re-created, and
Using identical vma region, cooperates dynamically load and Unload module, make lesser in m_module_1 and m_module_2
Vma size is released from memory；
S3: the optimization of intelligent terminal dynamic memory is completed.
Preferably, after the dlm (dynamic loading module) reads each submodule part of main program, decompression is loaded into interior
The specified Region deposited；And two will not the shared specified memory Region of simultaneous submodule.
Preferably, when cooperating dlm (dynamic loading module) and Unload module in the step S2, when two module mutually cut are provided
Source must assure that when loading a module, shared module resource exits completely together.
Compared with prior art, a kind of embedded intelligent terminal dynamic memory optimization method of the present invention stresses to analyze intelligent end
The memory behaviour in service at end, the application program bigger to demand or function, by reasonably match with dynamically load and unloading,
Accomplish that the Optimum utilization to memory, dlm (dynamic loading module) are decompression loads after reading each submodule part of main program
To the specified Region of memory, and two will not simultaneous submodule share specified memory Region, it is final realize it is internal
The ultimate attainment utilization deposited.
[Detailed description of the invention]
Fig. 1 is a kind of flow diagram of embedded intelligent terminal dynamic memory optimization method of the present invention.
[specific embodiment]
To make the purpose of the present invention, technical solution and advantage are more clearly understood, with reference to the accompanying drawings and embodiments, to this
Invention is further elaborated.It should be appreciated that specific embodiment described herein is used only for explaining the present invention, not
For limiting the invention.
Referring to Fig. 1, a kind of embedded intelligent terminal dynamic memory optimization method 1 of the present invention includes the following steps,
S1: setting decompresses load, the dlm (dynamic loading module) of unloading and dynamic offloading module for carrying out dynamic；
S2: creation m_module_1 and m_module_2；It determines two and two or more will not use (mutual exclusion) with the time
Function or application program, its respective .a (.o) is configured in the m_module_1 and m_module_2 re-created, and
Using identical vma region, cooperates dynamically load and Unload module, make lesser in m_module_1 and m_module_2
Vma size is released from memory；
S3: the optimization of intelligent terminal dynamic memory is completed.
The application stresses to analyze the memory behaviour in service of intelligent terminal, the application program bigger to demand or function, leads to
Reasonable matching and dynamically load and unloading are crossed, accomplishes that the Optimum utilization to memory, dlm (dynamic loading module) are by each of main program
After a sub- module section is read, decompression is loaded into the specified Region of memory, and two will not simultaneous submodule it is total
Specified memory Region is enjoyed, the final ultimate attainment utilization realized to memory.
Preferably, after the dlm (dynamic loading module) reads each submodule part of main program, decompression is loaded into interior
The specified Region deposited；And two will not the shared specified memory Region of simultaneous submodule.
Preferably, when cooperating dlm (dynamic loading module) and Unload module in the step S2, when two module mutually cut are provided
Source must assure that when loading a module, shared module resource exits completely together.
The present invention is configured, maximum elevator by pure software mode after combing to the functional module of intelligent terminal
The internal memory optimization of device uses.
The advantages of doing so:
1. accomplishing the ultimate attainment utilization to memory under limited hardware configuration, improving cost performance.
2. this method will not cause fragment to storehouse.Especially some intelligent terminals use embedded system, do not have interior
Deposit arrangement mechanism.When storehouse fragment, without biggish contiguous memory, lead to not load operating.
3. ensure that big program using independent reasonable memory headroom, starts and runs speed and is guaranteed.
Compared with prior art, a kind of embedded intelligent terminal dynamic memory optimization method 1 of the present invention stresses analysis intelligence
The memory behaviour in service of terminal, the application program bigger to demand or function, by reasonably matching and dynamically load and unloading
It carries, accomplishes that the Optimum utilization to memory, dlm (dynamic loading module) are after reading each submodule part of main program, decompression adds
Be downloaded to the specified Region of memory, and two will not simultaneous submodule share specified memory Region, it is final to realize pair
The ultimate attainment utilization of memory.
The embodiments of the present invention described above are not intended to limit the scope of the present invention.It is any in the present invention
Spirit and principle within made modifications, equivalent substitutions and improvements etc., should be included in claim protection model of the invention
Within enclosing.
