[0046] In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and their order is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0047] It should be noted that, in the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0048] In the present invention, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b and c, where a, b, c can be single or multiple.

[0049] There are mainly the following situations where embedded devices have insufficient storage space: 1. The storage unit space is insufficient, but there is free memory space to maximize support for more application functions; 2. The storage unit partitions are fixed, and the system partition space in the storage unit is insufficient: the storage unit space is sufficient and multi-partition management is performed. When adding functions in the new version, the system partition has insufficient remaining space, but the user partition is sufficient. Since the partitions of the old product are fixed, the system partition cannot be increased to place the new application; 3. Both storage space and memory space are insufficient.

[0050] In order to solve the problem that the storage space of the above embedded device is insufficient and new applications cannot be added, the present invention provides an application storage and startup method, device, equipment and medium, which will be described below with reference to the accompanying drawings.

[0051] join Figure 1 The present invention provides an application storage and startup method, such as Figure 1As shown, the method comprises the following steps:

[0052] Step 101: Obtain a compressed package of a first application and an embedded device;

[0053] The embedded device includes a storage unit and a memory unit; the compressed package of the first application is a newly added application compressed package;

[0054] Optionally, when the first application is a commonly used program, the first application is stored in a non-compressed form.

[0055] Step 102: compressing the second application originally stored in the storage unit to obtain a target remaining space of the storage unit;

[0056] The second application may be fully or partially compressed according to the remaining space of the storage unit to save storage space. For example, when the remaining space of the storage unit is greater than a preset space threshold, only infrequently used applications are compressed, and frequently used applications are not compressed. When the remaining space of the storage unit is less than the preset space threshold, all applications are compressed.

[0057] The compression algorithm can adopt common algorithms such as LZMA, Bzip2, Deflate, etc.

[0058] Step 103: storing the compressed package of the first application program in the target remaining space to obtain a compressed package of the target program;

[0059] The target program compressed package includes a compressed package of the first application program and a compressed package corresponding to the compressed second application program; CRC check information is stored at the end of the target program compressed package, which is used to check the integrity of the compressed package;

[0060] Optionally, a first directory is established in the storage unit, and the target program compressed package is stored in the first directory.

[0061] Newly added applications are stored in compressed packages, which can further save storage space.

[0062] Step 104: decompress the target program compressed package and then start it.

[0063] Since the target program compressed package is stored in compressed form, a running space needs to be allocated when the application is started to store the decompressed application for the application to run. A second directory is established in the running partition;

[0064] Specifically, step 104 specifically includes the following steps: find the compressed package to be started in the first directory according to the calling instruction; the compressed package to be started is the compressed package in the target program compressed package that matches the calling instruction; determine the integrity of the compressed package to be started according to the CRC check information, and when the compressed package to be started is complete, decompress the compressed package to be started and store it in the second directory to obtain the target program; call the target program and start the target program. If the system needs to call other applications, repeat step 104 by analogy.

[0065] As an optional manner, the calling of the target program, after starting the target program, further includes:

[0066] When the target program is called, the target program in the running partition is deleted to make room for subsequent system calls to other applications.

[0067] The present invention compresses the second application originally stored in the storage unit to obtain the target remaining space of the storage unit. When the storage space is insufficient, space can be freed up for the compressed package of the newly added first application to be stored in the target remaining space, wherein the newly added first application is also stored in the form of a compressed package, further saving space, and can be started by decompressing the compressed package at startup. The present invention can realize the addition of applications when the storage space of the embedded device is insufficient. It avoids the problem that when the embedded device has insufficient space, it cannot be upgraded and can only be eliminated. In addition, a running space is configured for the application to be decompressed, stored and run, so that the application is started.

[0068] based on Figure 1 The present invention also provides some specific implementation methods as follows.

[0069] As an optional method, before decompressing the target program compressed package and starting it, the method further includes:

[0070] Determining whether the remaining memory of the memory unit is less than a preset memory value;

[0071] If the remaining memory is less than a preset memory value, configuring the storage unit to run partitions;

[0072] If the remaining memory is greater than the preset memory value, the memory unit is configured to run partitions.

[0073] See also Figure 2When the remaining space of the memory unit is greater than the preset memory value, it means that the remaining space of the memory unit is sufficient. At this time, when designing the embedded software architecture, the second application originally stored in the storage unit is fully or partially compressed according to the remaining space of the storage unit, and the compressed application is placed in the first directory of the storage space. Configure the running partition A1 area in the memory unit for the virtual file system, and establish a second directory in the virtual file system to place the decompressed application; after the system is started, the file system and the second directory are virtualized for use when the system calls the program; during the system operation, when the application X needs to be called, the compressed package to be started corresponding to X is found in the first directory, and the integrity of the file is confirmed by CRC check. After the check passes, it is decompressed to the second directory, and the system calls the decompressed application X in the second directory to start and run the application X.

[0074] See also Figure 3 and Figure 4 When the remaining space of the memory unit is less than the preset memory value, it means that the remaining space of the memory unit is insufficient and the running partition cannot be configured. Therefore, it is necessary to configure the running partition in the storage unit to start and run the application.

[0075] For the case where the storage unit partition has been solidified, such as Figure 3 As shown, the storage unit already includes the first system partition A2, the user partition B2, the first data partition B3, and the second application is stored in the first system partition; because the storage unit is solidified, the partition cannot be modified. When the remaining space reserved for the first system partition is insufficient, the second application stored in the first system partition is partially or completely compressed to obtain the target remaining space; the newly added application compression package is stored in the target remaining space in the first system partition. When the user partition memory is sufficient, configuring the storage unit to run the partition includes: determining the user partition as the running partition of the storage unit. After the system is started, a first directory is established in the first system partition, and a second directory is established in the user partition for the system to use when it needs to call the compressed application; during the operation of the system, when it is necessary to call the compressed application, such as application 5, first find the compressed application 5 in the first directory of the first system partition, and after verifying that the compressed package is complete, decompress it to the second directory. The system calls the decompressed application 5 in the second directory to complete the startup and operation of application 5. It should be understood that the solidification of the storage unit means that the storage unit is partitioned before leaving the factory, and the storage unit cannot be partitioned later.

[0076] Exemplarily, the second application includes applications 1 to 6, which are all placed in the first system partition in an uncompressed manner. After new requirements or function iterations, the newly added applications are applications 7 and 8. Due to insufficient storage space in the first system partition, they cannot be placed in the system partition in an uncompressed manner. Therefore, infrequently called applications 5, 6, and 7 can be selected for compressed storage, and frequently used applications 1, 2, 3, 4, and 8 are still placed in the first system partition in an uncompressed manner.

[0077] For the case where the storage unit is not fixed partition, such as Figure 4 As shown, configuring the storage unit to run the partition includes:

[0078] The second application is divided into a third application and a fourth application according to the number of historical calls of each program in the second application, wherein the third application is an application whose number of historical calls in the second application is less than a preset number; the fourth application is an application whose number of historical calls in the second application is greater than a preset number; then the storage unit is divided into a second system partition A3 area, an application partition B3 area, a running partition C3 area and a second data partition D3 area; wherein the third application is stored in the application partition, and the fourth application is stored in the second system partition. The application partition is used to store compressed programs, and the second system partition is used to store programs that cannot be compressed or are not compressed.

[0079] At this time, compressing the second application originally stored in the storage unit to obtain the target remaining space of the storage unit includes: compressing the third application stored in the application partition to obtain the target remaining space. When the newly added application is an infrequently used program, the newly added application is compressed and stored in the application partition; when the newly added application is a frequently used program, the application is stored in the second system partition. After the system is started, the program in the application partition is decompressed into the running partition as needed, and the decompressed application is called at the same time.

[0080] The embodiment of the present invention can divide the functional modules according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present invention is schematic and is only a logical function division. There may be other division methods in actual implementation.

[0081] In the case of dividing each functional module into corresponding functional modules, Figure 5 FIG. 2 shows a schematic diagram of the structure of an application storage and startup device provided by the present invention. Figure 5As shown, the device comprises:

[0082] The data acquisition module 501 is used to acquire a compressed package of a first application and an embedded device; the embedded device includes a storage unit; the compressed package of the first application is a newly added compressed package of an application;

[0085] The startup module 504 is used to decompress the target program compressed package and then start it.

[0090] Optionally, when the storage unit includes a solidified first system partition, a user partition, and a first data partition; the storage unit configuration unit may be specifically configured to determine the user partition as the running partition of the storage unit.

[0092] Optionally, the compression module 502 may be used to:

[0098] Optionally, the device further includes a cleaning module, which is used to delete the target program in the running partition after the target program is called.
