Embodiment Construction

[0049] Below in conjunction with specific embodiment the present invention is described in detail:

[0050] figure 1 It is a schematic diagram of the storage area of ​​the storage unit of the embedded device of the present invention. The storage unit is divided into three areas in the present invention: a file pointer area, a page allocation table area and a single board information storage area. Among them, the file pointer area is used to store the first address of each board information in the storage unit; the page allocation table area records the storage page usage of the storage unit; the board information storage area is used to store the data information of the board, and temporarily stores Upgrade software and default drivers.

[0051] Let’s take EEPROM as an example to illustrate. A common EEPOM chip such as AT28C64B, 64K bit (8K×8) parallel EEPROM, interface is intel bus mode, write cycle<10ms, can be written by page, each page can be up to 64 bytes, can be passed...

Abstract

The invention relates to a file management method of embedded equipment and a system. The embedded equipment is used for monitoring a single communication board in a communication system, all storage spaces of a storage unit of the embedded equipment are initialized, a hash table is established in a pointer area of the file, hash operation is conducted on a hardware address of the single communication board. According to a hash code acquired by the hash operation, the position of a first address of the single board information in the hash table is determined and the first address is stored in the hash table. The zone of a page distribution sheet is used for recording the state of a page stored with the single board information, upgrade software and default drivers. According to the capacity of the single board information, the pages with required number are distributed in the storage area of the single board information, and the pages storing the single board information are caused to logically form a continuous data storage area through a list structure. The invention can solve the problem of insufficient utilization rate of the storage space and improve the access speed as well as the working efficiency of files.

Description

technical field [0001] The invention relates to file management of embedded devices, in particular to a method and system for file management of single boards in communication devices. Background technique [0002] In the field of mobile communication, a complete communication system is usually a multi-processor distributed system composed of many single boards. Each single board runs its own operating system, installs specific software programs, and performs specific tasks. The software and configuration files of the board are stored on the storage unit. EEPROM (Electrically Erasable Programmable Read Only Memory) and FLASH (FLASH memory) are commonly used non-volatile memories, which are usually used in communication products to store software programs and data configurations run by processors document. [0003] When performing device monitoring on pluggable single boards, an embedded device is used to store the running status, configuration information and alarm inform...
