The present invention relates to an apparatus and method for providing resource management using a linear file system. More particularly, the present invention relates to a resource and a resource such as a string and a bitmap in an embedded system mainly used in a mobile communication terminal. The present invention relates to an apparatus and a method for providing resource management using a linear file system that enables sharing in a network and efficiently utilizes limited memory.

In general, embedded system environment mainly used in mobile communication terminal does not support memory and storage space of PC environment level.

Due to the nature of the embedded system environment, which requires the best performance with minimal memory and storage space, highlighting one part may adversely affect the other part, so various devices and methods are proposed to satisfy the two parts. One of them is the apparatus and method for managing the fluid resources such as strings and bitmaps required for application operation.

1 is a view showing the configuration of a resource management system of a mobile communication terminal according to the prior art.

The resource management system 101 of the mobile communication terminal according to FIG. 1 is interlocked with an application 105 running through the mobile communication terminal and stores a file storage area of the flash memory 103 through an embedded file system (EFS) 102 ( Resources are managed by loading, recording, or deleting files in 103a).

On the other hand, the resource management system 101 assigns a unique ID to each of the files stored in the file storage area 103a of the flash memory 103 and assigns this ID information to the ID information DB 104a of the nonvolatile memory 104. ), And file information of files recorded or deleted in the file storage area 103a is stored in the file information DB 103b of the flash memory 103 for each ID.

Accordingly, the resource management system 101 of the mobile communication terminal according to the related art stores and manages unique ID information assigned to each file in the nonvolatile memory 104 separately, and uses the ID to store the corresponding file information DB or the corresponding information. Because accessing to a file allows efficient resource management such as easy file access, it is possible to manage IDs in a DB.However, if the system does not use the DB or the performance of the DB does not support row data such as bitmaps, as the ID is stored in the DB. Has no meaning.

In addition, even if the ID search unit stored in the DB is separately included, the search time may affect the system speed.

An object of the present invention is to enable sharing of resources such as strings and bitmaps in all applications in an embedded system mainly used in a mobile communication terminal through an apparatus and method for providing resource management using a linear file system.

Another object of the present invention is to provide a resource management using a linear file system in an embedded system by enabling the sharing of resources such as strings, bitmaps in all applications in an embedded system mainly used in a mobile communication terminal Its purpose is to efficiently manage scarce resources.

The objects of the present invention are not limited to the above-mentioned objects, and other objects that are not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, an apparatus for providing resource management using a linear file system according to an embodiment of the present invention includes a resource storage unit for storing resource files and description files in a continuous linear form, and loading and initializing stored resource files. And an initialization setting unit to initialize the memory, a memory loading unit for loading the stored description file into a memory, and a file access unit for accessing the resource file using the loaded resource file and the description file.

In order to achieve the above object, a method for providing resource management using a linear file system according to an embodiment of the present invention includes a resource storage step of storing a resource file and a description file in a continuous linear form, and loading and initializing the resource file.

Specific details of other embodiments are included in the detailed description and the drawings.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and only the embodiments make the disclosure of the present invention complete, and the general knowledge in the art to which the present invention belongs. It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram illustrating a configuration of an apparatus for providing resource management using a linear file system according to an exemplary embodiment of the present invention.

An apparatus for providing resource management using a linear file system according to an embodiment of the present invention includes a resource storage unit 201 for storing resource files and a description file in a continuous linear form, and an initialization setting unit for loading and initializing the stored resource files. 202, a memory loading unit 203 for loading the stored description file into the memory at initialization, and a file access unit 204 for accessing the resource file using the loaded resource file and the description file.

3 is a flowchart illustrating a process of creating a resource file using the apparatus shown in FIG. 2.

The resource storage unit 201 stores various resource files and description files in the storage in succession (S301).

When continuously stored in the storage, it is stored as read-only, so that resource files can be stored in a linear form, and the offset of the files can be predicted in advance.

The offset is the value added to the base address to make the second address. For example, if C points to the address of address 100 in the formula below, the result (A) of the formula means address 107. something to do.

A = C + 7

Here, '7' in this expression is an offset.

Representing an address using an offset is called relative addressing, because the resulting address is relative to another point. Offset is also called displacement in other words.

After building the resource (S302) and calculating the resource ID and the pre-predicted offset in the description file (S303), the resource ID and the calculated offset are stored again in the description file (S304).

Resource files are generated via S301 to S304 (S305).

Since application and resource files are separated, more flexible operation is possible, and when modifying or updating later within the first created frame, it is necessary to build only resources without rebuilding the application (S302). File creation is possible.

Also, if you create multiple description files or change some of the structure, other additional support can be provided for other applications that share the resource files together.

4 is a flowchart illustrating a process of extracting (requesting) a resource file generated through the flow shown in FIG. 3 from an application.

As described above with reference to FIG. 3, since the generated resource file is separated from the execution file of the application, the file can be modified within the downloaded and created frame, and between independent applications that can read and write data from other applications to the mapped memory map as a file. Since it uses Memory Mapped IO, which is a method of exchanging data, resource files need to be initialized when the application runs.

Initialization of the resource file is initialized by loading the stored resource file through the initialization setting unit 202 (S401).

At this time, the base address is found in advance using the memory mapped IO (S402).

If the description file is continuously read every time the resources are generated, since the overhead is large, the memory loading unit 203 after S402 loads the description file into the memory (S403).

The file access unit 204 extracts the resource ID of the resource requested by the application from the description file loaded in S403 (S404).

If the resource ID exists, the offset of the file associated with the corresponding resource ID is obtained and the resource pointer position is returned using the start address and the offset of the corresponding resource through the memory mapped IO (S405).

Using the pointer returned in S405, the corresponding resource is available as if using real memory (S406).

If the resource ID of the corresponding resource does not exist as a result of S404, the file access unit 204 terminates the operation.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.

According to the apparatus and method for providing resource management using the linear file system of the present invention as described above, there are one or more of the following effects.

First, since resource files created through devices and methods that provide resource management using a linear file system are separated from application executable files, resources such as strings and bitmaps are embedded in embedded systems mainly used in mobile communication terminals. The advantage is that it can be shared by all applications.

Second, through a device and method that provides resource management using a linear file system, resources such as strings and bitmaps can be shared among all applications in an embedded system mainly used in a mobile communication terminal, thereby efficiently eliminating resources that are insufficient in an embedded system. There is also an advantage to manage.
