BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal. In particular, in a mobile communication terminal in which a backend chip such as a graphics accelerator is embedded in addition to a mobile station modem (MSM), a specific file may be stored in a personal computer (PC). When downloading to the embedded memory in the end chip, the download application program for performing the file download by mapping the physical address of the back and chip memory to the MSM memory as a virtual address, so that when the file is downloaded to the back and chip memory The present invention relates to a method for downloading a file to a mobile communication terminal equipped with a backend chip that can be downloaded to the backend chip memory as one binary at a time without generating a separate binary for a backend chip memory.

NAND-type flash memory, a type of nonvolatile flash memory that is preserved without losing data even when the power is turned off, selects a block prior to a read operation with cells connected in series. The reading speed is slow due to the need, but the writing speed is faster, the manufacturing cost is cheaper than the NOR-type, and the capacity is large, which is why digital cameras, MP3 players, PDAs (Personal Digital Assistants), mobile communication terminals, etc. Mainly used.

When downloading a specific file from the personal computer (PC) to the NAND flash memory built into the mobile communication terminal, the next load application executed for downloading the file on the PC is stored in the binary address, data, and storage of the specific file. If you know only the NAND memory address you want to download, you can download.

As shown in Fig. 1, for example, when downloading data from address 0 to 1000 of a file, data is written from address 0 to 1000 of the memory. In this case, the download application program on the PC can be downloaded simply by knowing the address range of the memory in the mobile communication terminal.

However, when a backend chip is used for a graphic accelerator or the like in addition to a mobile station modem (MSM) chip in a mobile communication terminal, a download application program is used to download a file to a separate memory embedded in the backend chip. Needs a separate binary for the backend chip, so it cannot download the file directly into the backend chip's memory, but downloads the file to main memory using the existing binary and then uses the binary for the backend chip. In order to download back to the memory of the back-end chip, since the download must be performed using a number of binaries corresponding to the number of the back-end chip memory, the user is inconvenient and the download speed decreases as much. .

In order to improve this, the download application program should be configured according to the characteristics of the back end chip memory. In this case, a company providing the download application program may use a back end chip memory according to various back end chips installed in the mobile communication terminal. Since the new download application is compatible with the previous version only when you have the information, you need to waste a lot of time and manpower to exchange information with the company that provides the download application every time you install a new back-end chip. there was.

Accordingly, the present invention has been proposed to solve the above-described problems, and in the mobile communication terminal having a backend chip such as a graphic accelerator in addition to the mobile station modem (MSM), a personal computer (PC) Downloads a specific file to the MSM or backend chip's built-in memory, a file download method that allows the download application for file download to map the backend chip memory's physical address to the MSM's memory as a virtual address. The purpose is to provide.

In order to achieve the above object, the present invention uses a download application to download a specific file from a personal computer (PC) to a mobile communication terminal. Setting a binary address for a mobile station modem (MSM) memory and a backend chip memory in the mobile communication terminal by using; And performing a download using a real address or a virtual address set in the MSM memory or the back-end chip memory with reference to the set binary address.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart illustrating an operation of a file download method to a mobile communication terminal equipped with a backend chip of the present invention. As shown in FIG. 2, a specific file is transferred from a personal computer (PC) using a download application program. When downloading to a terminal, when a download application is executed and a file download request is generated, a binary address for MSM (Mobile Station Modem) memory or backend chip memory in the mobile communication terminal is set using a virtual address. Step S20 and S21; By performing the download using the actual address or the virtual address set in the MSM memory or the back-end chip memory with reference to the set binary address.

The present invention can be applied to a mobile communication terminal having a built-in backend chip such as a graphic accelerator in addition to the mobile station modem (MSM), and a specific file is transmitted from the PC to the MSM memory or the back-and-chip memory of the mobile communication terminal. In case of downloading to file, download file such as manager program to perform file download is managed by mapping real address of backend chip memory to virtual address to MSM memory. Rather than having to create a separate binary for the backend chip memory, it downloads into the backend chip memory as one binary at a time to improve the download speed.

The present invention can be implemented by changing a download application program such as a manager program for enabling the file download from the PC to the mobile communication terminal in software, wherein the download application is stored in the PC, the mobile communication terminal It is assumed that an MSM chip and two backend chips are embedded and each chip includes an MSM memory or a backend chip memory.

First, when the user connects the PC and his mobile communication terminal with a cable, executes a download application stored in the PC, and requests a download from the PC to the mobile communication terminal for a specific file (S20). The application program acquires the memory information stored in the RAM area of the mobile communication terminal. As shown in FIG. 3, for the MSM memory, an actual address (0x0 to 0x1000000) corresponding to the storage area is used. A binary address is set and a binary address is set using a virtual address (0x1000001 to 0x1010000) in which an address for the backend chip is added to an actual address (0x0 to 0x1000000) of the MSM memory. Thus, even though there are a plurality of memories, one PC-side binary address file to be referred for file download is generated (S21).

That is, in case of downloading a file to the backend chip memory other than the MSM memory, a binary file for the MSM memory must be generated in order to perform a download from the download application to the backend chip memory at once. The present invention is implemented by adding a binary address for at least one backend chip memory to the address, wherein the binary address of the backend chip memory added to the MSM memory is managed as a virtual address.

For example, if the MSM memory uses 1000000 addresses ranging from '0x1' to '0x1000000', subsequent address areas ranging from '0x1000001' to '0x1010000' are stored in the address information of the first and second backend chip memories. The binary address is set by mapping to the virtual address accordingly.

In other words, the binary address of address '0x1000001' to '0x1010000' added to the MSM memory is not a real memory address but a virtual memory address, which is downloaded depending on whether it is downloaded to MSM memory or back-end memory. The application program executes the download using the real address or the virtual address set in the MSM memory or the backend chip memory with reference to the binary address set in the step S21 (S22 to S25).

For example, in a binary file managed by a download application, when a user wants to download data within the address of '0x1000000' to the mobile terminal, the download application recognizes that the download application is executed to the MSM memory. The control is executed to download to the MSM memory using the actual address of the MSM memory referred to.

On the other hand, when the user wants to download the data after the address '0x1000001' to the mobile communication terminal, the download application recognizes that the download is executed to the first or second backend chip memory other than the MSM memory. By referring to an address and converting a virtual address on the referenced binary address into a real address and controlling the download to be executed using the converted real address, the download application program is stored in a mobile terminal due to a binary file. While it considers the download to be performed on the memory, it actually downloads the data to the backend chip memory.

In general, since the download process may vary depending on the structure and characteristics of the backend chip installed in the mobile communication terminal, the download application should be changed accordingly, but the actual size of the backend chip memory mapped to the virtual address of the MSM memory Since the file can be downloaded to the backend chip memory only by knowing the address, a download application can be developed irrespective of the structure and characteristics of the backend chip. For the terminal manufacturer, the backend chip is independent of the download application. There is an advantage to manufacture a terminal equipped with.

As described above, the present invention is a mobile communication terminal having a built-in backend chip such as a graphics accelerator in addition to the mobile station modem (MSM), a specific file in a personal computer (PC) to the MSM or back-end chip When downloading to the built-in memory, the download application for performing a file download by mapping the physical address of the back and chip memory to the virtual address to the MSM memory, and manages, when downloading the file to the back and chip memory the back and chip memory There is an effect of improving the download speed by downloading a single binary to the back end chip memory at a time without having to create a separate binary for.

In addition, the present invention can download the file to the back-end chip memory only knowing the actual address of the back-end memory mapped to the virtual address of the MSM memory, according to the structure and characteristics of the back-end chip to download the application program This can be developed without changing, and thus, the terminal manufacturer has an effect of manufacturing a mobile communication terminal equipped with a backend chip independently of the download application program.
