The operation of installing the program using the compressed file in the control unit 140 as described above will be described later in more detail with reference to FIG. 2.

2 is a block diagram illustrating an operation of installing a program using a compressed file in the program installation apparatus according to an embodiment.

As illustrated in FIG. 2, the communication unit 120 may receive a compressed file compressed with a program. The communication unit 120 may store the compressed file in the main memory 131 to decompress the received compressed file. The compressed file may be composed of a plurality of unit compressed files or a plurality of compressed divided files. In addition, compressed split files can have the same file structure for each other to install programs by parallel processing, for example, decompressing the compressed files simultaneously with the reception of the compressed files, and individually complete, i.e., a complete single file It can take the form. Therefore, the communication unit 120 may sequentially receive the compressed split file and store it in the main memory 131.

The main memory 131 is a memory in which compressed files are stored. In addition, the program decompressed by the control unit 140 may be temporarily stored in the main memory 131 before being stored in the auxiliary memory 132.

The control unit 140 may decompress the compressed file stored in the main memory 131. The control unit 140 may directly install the program obtained by decompressing it in the auxiliary memory 132.

Meanwhile, the controller 140 may perform a decompression operation in the main memory 131. In addition, the control unit 140 may control to install the decompressed program in the auxiliary memory 132 after temporarily storing it in the main memory 131 before storing it in the auxiliary memory 132. Since the above-described operations are illustrated by dotted lines in the drawing, and the processing speed of the main memory 131 is faster than the processing speed of the auxiliary memory 132, the memories 131 and 132 according to the program installation through the above-described operations The difference in the processing speed of the liver can be overcome.

When decompressing the compressed file, the controller 140 may decompress the compressed file in a predetermined unit. For example, the controller 140 receives the first unit compressed file of a predetermined unit and stores it in the main memory 131, and simultaneously decompresses the second unit compressed file of the predetermined unit stored in the main memory 131. It is stored in the auxiliary memory 132. Here, the first unit compressed file and the second unit compressed file may have a size of 1 bit or more, and may have the same size or different sizes. For example, in the compressed file, the compressed file of the first unit may be located after the compressed file of the second unit.

When decompressing the compressed file, the controller 140 may decompress the compressed file in units of compressed files. Through this, the controller 140 may decompress the compressed partition file and install a program obtained by decompressing. At this time, the main memory 131 may receive a compressed split file after the compressed split file that has been decompressed by the controller 140.

When installing the program as described above, the control unit 140 may install a program that decompresses the compressed file at the same time as receiving the compressed file using a unit compressed file or a compressed divided file.

3 is a view for explaining a program installation operation according to an embodiment.

As illustrated in FIG. 4, a compressed file 210 of a program may be stored in the main memory 131. Here, the compressed file 210 may be divided into first to third unit compressed files C1, C2, and C3 compressed by splitting or dividing and compressing the program 220 into two or more, and the program 220 May be divided into first to third programs P1, P2, and P3.

Therefore, the program for installation may be divided into each of the first to third unit compressed files, individually compressed, and received from the communication unit 120.

In the first section t1, the first unit compressed file C1 is received, and the first unit compressed file C1 is stored in the main memory 131.

In the second section t2, the second unit compressed file C2 after the first unit compressed file C1 is received, and the second unit compressed file C2 is stored in the main memory 131.

At this time, when the storage of the first unit compressed file C1 in the main memory 131 is completed, the controller 140 may decompress the first unit compressed file C1. In addition, the control unit 140 may install the first program P1 obtained by decompressing the first unit compressed file C1 in the auxiliary memory 132.

In the third section t3, the third unit compressed file C3 after the second unit compressed file C2 is received, and the third unit compressed file C3 is stored in the main memory 131.

At this time, when the storage of the second unit compressed file C2 in the main memory 131 is completed, the controller 140 may decompress the second unit compressed file C2. In addition, the control unit 140 may install the second program P2 obtained by decompressing the second unit compressed file C2 in the auxiliary memory 132.

In the fourth section t4, when the storage of the third unit compressed file C3 in the main memory 131 is completed, the controller 140 may decompress the third unit compressed file C3. In addition, the control unit 140 may install the third program P3 obtained by decompressing the third unit compressed file C3 in the auxiliary memory 132.

Meanwhile, each of the unit compressed files C1, C2, and C3 may be configured in the same or different units, and at least some of them may be set in different units.

In FIG. 3, for convenience of description, the description is based on the unit compressed files C1, C2, and C3, but when the program 220 is installed using a compressed split file instead of the unit compressed files C1, C2, and C3, The same can be applied to.

Here, the first to third programs P1, P2, and P3 are divided into one program, and the first to third programs P1, P2, and P3 may be sequentially installed in the auxiliary memory 132. .

As described above, as described in the second section t2 and the third section t3, the program installation apparatus 100 downloads the compressed file to the main memory 131 using a unit compressed file or a compressed divided file, The compressed program may be installed in the auxiliary memory 132 by decompressing the compressed file.

As described above, since the program installation apparatus 100 can receive compressed data and decompress it at the same time, after receiving the entire compressed file, the compressed file is released and the memory capacity is minimized compared to the method of installing the program. Is done. For example, when 8 GB (GB) of an existing program is installed, the double auxiliary memory area uses 16 GB of memory area, but the program installation device 100 uses only the main memory 131 to play the game. Since it is directly installed in the auxiliary memory 132, an area other than the area to be installed of the program in the auxiliary memory 132 is not required.

For reference, a predetermined delay time according to movement of data between the main memory 131, the control unit 140, and the auxiliary memory 132, for example, of the compressed split file stored in the main memory 131 by the control unit 140 There may be a time required for loading, etc., but is not shown here for convenience of explanation.

The program installation device 100 may decompress the compressed file and store it in the auxiliary memory, and simultaneously receive the compressed file and store it in the main memory (S320).

At this time, the program installation apparatus 100 may decompress simultaneously while downloading the compressed file only partially to the main memory. Therefore, the maximum size of the compressed file or the compressed divided file may be set regardless of the memory capacity.

The program installation device 100 decompresses a portion of the received compressed file and stores it in the auxiliary memory, and simultaneously stores another portion of the compressed file in the main memory. The program installation apparatus 100 may perform parallel processing of receiving a compressed file in the form of a unit compressed file or a compressed divided file and simultaneously decompressing and storing the compressed file in a secondary memory.

Next, the program installation apparatus 100 determines whether the installation of the program is completed (S330).

As a result of the determination in step S330, if the installation of the program is not completed, the program installation device 100 proceeds to step S310 to decompress the received compressed file to continue the program installation operation or receive a new compressed file. can do. However, as a result of the determination in step S330, when the installation of the program is completed, the program installation apparatus 100 ends the installation operation of the program.

Meanwhile, the program installation apparatus 100 may include information for decompression in a compressed file at the beginning of the compressed file, for example, in a header. In this way, the program installation apparatus 100 may verify the decompression operation or the decompressed program using the information for decompression. In addition, the program installation apparatus 100 may check information for decompression in advance, and allocate a memory area for storing a compressed file or a program. At this time, the apparatus for installing a program may allocate an area for receiving a compressed file in the main memory or an area for installing a program in the auxiliary memory.

It can have a repeating structure.

As described above, even if the compressed divided files 510 and 520 are divided, they may be divided and compressed to have the same file structure for parallel processing.

Therefore, the compressed partitioned file has the same file structure among files, and may be a structure having a specific file structure in a form such as a header, a directory portion, and a member portion, but the unit compressed file is a compressed file by the program installation device 100 In can mean the minimum unit that can decompress. Therefore, the size of the unit compressed file may be composed of a relatively small size or a small number of bits compared to the size of the compressed divided file. 7 is a diagram illustrating a structure of headers included in a compressed file according to an embodiment.

As shown in FIG. 7, the headers 610, 620, and 630 included in the compressed split file are divided into, for example, a file header 610, a directory header 620, and a member header 630.

Accordingly, the first control module 141 and the second control module 142 may alternately decompress the compressed files divided in the main memory 131, that is, the compressed divided files, and install them in the auxiliary memory 132. For example, the first control module 141 decompresses the compressed partition file in the odd order, and the second control module 142 decompresses the compressed partition file in the even order. Through this, the first control module 141 and the second control module 142 may install the decompressed program in the auxiliary memory. In this case, since the decompression is processed in parallel by the control modules 141 and 142, the installation and decompression of the program can be performed separately in the two control modules, thereby shortening the time required for program installation. have.

In addition, the first control module 141 and the second control module 142 may compare the throughput of the processor according to the operation being performed. Through this, one control module having a relatively high throughput (or processing speed) may be selected, and decompression and program installation operations may be performed by the selected control module.

For example, when the first control module 141 has a higher throughput than the second control module 142, the first control module 141 may decompress the compressed file to install a program.
