Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The data management method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of steps of a data management method according to an embodiment of the present application is shown.
The data management method of the embodiment of the application comprises the following steps:
step 101: and determining the type of the application program based on the preset parameters.
Wherein the preset parameters include at least one of the following: the method comprises the steps of presetting information by a user, using frequency of an application program and analyzing results of characteristics of the user.
The data management method shown in the embodiment of the application manages data of each application program installed in the electronic device. In the embodiment of the present application, the management of data of one application is taken as an example, and in a specific implementation process, the data management device refers to a data management flow shown in the embodiment of the present application to manage data of each application installed in the electronic device.
The types to which the application belongs may include: a first type and a second type. The first type may be an application program with a use frequency higher than a preset frequency in a preset time period, that is, an application program commonly used by a user, and the second type may be an application program with a use frequency lower than or equal to the preset frequency in the preset time period, that is, an application program not commonly used by the user.
Step 102: and adding the corresponding relation between the logical page address and the physical page address of the application program data into the page mapping table under the condition that the type is the first type.
And adding the corresponding relation between the logical page address and the physical page address of the application program data into a page mapping table, namely managing the application program data of the first type in a page mapping mode. The application program data is managed in a page mapping mode, so that the address conversion efficiency is higher, and the address allocation is more flexible.
For the second type of application, the data is managed in a block mapping manner.
Step 103: and in the case that the type is the second type, adding the corresponding relation between the logical page address and the physical page address of the application program data into the block mapping table.
And adding the corresponding relation between the logical page address and the physical page address of the application program data into a block mapping table, namely managing the data by adopting a block mapping mode. The block mapping mode is a conventional data address mapping mode in the prior art. The data of the second type application program is managed in a block mapping mode, so that occupation of memory space of the storage device can be reduced, and the response speed of the application program for reading and writing requests can be sacrificed because the second type application program is an application program which is not commonly used by users.
At present, the address mapping mode of the flash memory storage device in the electronic device is relatively fixed, the address conversion time cost is high, and further, the read-write request response delay of the application program is caused, so that a user feels the phenomenon of blocking the application program. In order to solve the problem, in the method, when the data of the first type application program installed in the electronic equipment is managed, a page mapping mode with higher address conversion efficiency and more flexible address allocation is adopted, and because the memory space for storing the address conversion page table is limited, the block mapping mode which saves more memory space is adopted for the data of the second type application program installed in the electronic equipment, so that the problem of blocking in the running process of the first type application program can be prevented while the limited memory space is fully utilized.
In addition, in the use process of the electronic equipment, the use habit changing condition of the user on each application program can be continuously learned, the type of each application program in the electronic equipment is adaptively adjusted based on the learned use habit changing condition, and correspondingly, when the type of the application program is changed, the management mode of the data of the application program is adaptively changed. For example: when an application program is changed from a first type to a second type, the data management mode of the application program is changed from page mapping to block mapping; for another example: when an application program changes from the second type to the first type, the data management mode of the application program changes from block mapping to page mapping. The technical means of self-adaptively adjusting the management mode of the application program data according to the use habit change of the user on each application program can effectively prevent the response delay problem of the application program commonly used by the user due to the address mapping overhead while fully utilizing the limited memory space of the memory.
According to the data management method provided by the embodiment of the application, the type of the application program is determined based on the preset parameters; under the condition that the type is the first type, adding the corresponding relation between the logical page address and the physical page address of the application program data into a page mapping table; and in the case that the type is the second type, adding the corresponding relation between the logical page address and the physical page address of the application program data into the block mapping table. According to the data management method provided by the embodiment of the application program, the types of the application programs installed in the electronic equipment can be divided, the data of the first type of the application programs are stored in a page mapping mode, and the data of the other types of the application programs are stored in a conventional block mapping mode. The storage mode of the block mapping can save occupied memory space, the storage mode of the page mapping can improve response speed of read-write requests of the application programs, in the embodiment of the application, the data of each installed application program is stored by combining the page mapping mode and the block mapping mode, the response speed of the read-write requests of the first type application program can be ensured without expanding the memory space, and smoothness of the first type application program in use is ensured. The memory space is not required to be enlarged, so that the cost and the design difficulty of the electronic equipment are not increased additionally.
In an alternative embodiment, when determining the type of the application program based on the preset parameters, the method may be implemented by an application program type determining method shown in fig. 2, and specifically includes the following steps:
step 201: and acquiring user preset information input by a user in advance.
Wherein the user preset information includes at least one of: sex information, preference information.
The user can show different tendencies in daily habits, the characteristics of the user can be defined when the user uses the electronic equipment for the first time, and the application programs which are used more frequently by the user can be primarily judged according to the characteristics of the user. The user preset information may be used as a dimension to determine the user's trait. In the specific implementation process, a guiding interface can be displayed when the user uses the electronic equipment for the first time, and the user is prompted to input gender information, hobby information and the like so as to acquire preset information of the user.
User preferences may include, but are not limited to: games, chasing plays, chats, and delicacies. In inputting the preference information, the user may input one or more preference information. For example, if the user input preference information is a game, the user may be determined to be "game control" preliminarily, and if the user input preference information is a chasing, the user may be determined to be "video control" preliminarily.
Step 202: a frequency of use ranking of the applications is determined based on historical operational data for each of the installed applications.
The frequency of use of each application installed in the electronic device is ranked periodically during the use of the electronic device by the user. The higher the frequency of use ranking of an application, the more often the user will use the application. The usage frequency ranking of each application is also used as a dimension that characterizes the user's features.
Step 203: and analyzing the managed preset type data to obtain a user characteristic analysis result.
The preset type data is data in a low risk application program, for example: the short message is analyzed to obtain information such as user hobbies, living habits and the like by means of keyword extraction, matching and the like on the preset type data, and the information is used as a user characteristic analysis result.
Step 204: and determining the type of the application program according to the user preset information, the use frequency ranking and the user characteristic analysis result.
After obtaining the information of three dimensions characterizing the characteristics of the user through steps 201 to 204, determining the type of each application program installed in the electronic device based on the information of the three dimensions.
For example: the information in three dimensions may be weighted to derive a ranking for each application installed in the electronic device. And setting a threshold T, determining the application programs ranked in the top T% as the first type application programs, and determining the rest application programs as the second type application programs.
It should be noted that, steps 201 to 203 are not limited to the above-described sequence, and the three steps may be executed in parallel without any restriction on the sequence of execution among the three steps. In the specific implementation process, the method is not limited to determining the type of the application program through three pieces of three-dimensional information, and the type of each application program installed in the electronic device can be determined based on any one or two pieces of the three pieces of dimensional information.
The manner in which the type of application is optionally determined as shown in steps 201-204 is more accurate and reliable.
In an alternative embodiment, after adding the correspondence between the logical page address and the physical page address of the application program data to the page mapping table, the following procedure is further included:
under the condition that a data request of an application program is received, determining a target logical page address corresponding to the data request; and searching the target physical page address corresponding to each target logical page address according to the mapping relation between each logical page address and the physical page address managed in the page mapping table.
Under the condition that a data request of the first type application program is received, the page mapping table is used for directly positioning a physical storage address corresponding to the request, and accessing the address, so that the response time of the data request can be shortened, and smooth operation of the application program is ensured.
In an alternative embodiment, after the correspondence between the logical page address and the physical page address of the application program data is added to the page mapping table, the following application program data management flow may be further included:
firstly, updating the type of an application program according to a preset parameter corresponding to the application program;
the update of the type of the application program can be performed at intervals of a preset time, or can be performed when the electronic device is in an idle state.
When the type of the application program is updated according to the preset parameters corresponding to the application program, the type of each application program installed in the electronic equipment is redetermined based on the mode shown in fig. 2, and the redetermined type is compared with the type recorded in the system for each application program, and if the comparison result is that the type is unchanged, the type of the application program is not changed; if the comparison result shows that the type is changed, the type recorded in the system is replaced by the redetermined type so as to complete the updating of the type to which the application program belongs.
And secondly, when the type of the application program is changed from the first type to the second type, the corresponding relation between the logical page address and the physical page address of the application program data is transferred from the page mapping table to the block mapping table.
For example: if the application rank is changed from the top T% to the bottom (100-T)%, the type of the application is changed from the first type to the second type, and the management mode of the application data from page mapping is changed to the management mode of block mapping.
The physical addresses of data in the block mapping mode should be continuous, so if the data of a certain application program is converted from page mapping to block mapping, the data of the original page mapping needs to be migrated, the data are stored in a storage unit with continuous addresses in a concentrated way, and after the data are migrated, a block mapping table is built for the migrated data again.
The method can update the application program type optionally, and can effectively utilize the memory space of the memory of the electronic equipment by adopting the technical means of adaptively adjusting the application program data management mode according to the type.
In an alternative embodiment, after adding the correspondence between the logical page address and the physical page address of the application program data to the block mapping table in the case that the type to which the application program belongs is the second type, the following application program data management flow may be further included:
Firstly, updating the type of an application program according to a preset parameter corresponding to the application program;
the specific manner of updating the type of the application program according to the preset parameters corresponding to the application program is just referred to the above related description, and will not be described herein.
And secondly, when the type of the application program is changed from the second type to the first type, the corresponding relation between the logical page address and the physical page address of the application program data is transferred from the block mapping table to the page mapping table.
For example: if the application rank is changed from the back (100-T)% to the front T%, the type of the application is considered to be changed from the second type to the first type, and the management mode of the application data from the block mapping is changed to the page mapping management mode.
The address mapping unit of the page mapping mode is a page, so after the data of the application program is converted from block mapping to page mapping, a corresponding page table item needs to be established for each page in the block so as to realize quick indexing of the data of the application program.
The method can be used for selectively updating the application program types, and the technical means of the application program data management mode can be adjusted according to the type adaptability, so that the response speed of the first type application program read-write request can be ensured, the first type application program can be smoothly operated, and the use experience of a user is improved.
