Problems solved by technology

[0004] When using the first method, if one of the information is to be modified, all subsequent information will be moved; when the specified information is to be read, the entire file must be analyzed and interpreted to obtain the specified information, run less efficient
[0005] The second method is used to realize the independence of information. Although it can be written and queried separately, due to the simple definition of the format, it lacks flexibility and scalability after pre-setting. If the length of the information in the new version of the system exceeds the specified The maximum length, you can only redesign and write the code of the entire information storage module

Embodiment Construction

[0045] The method of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] Referring to FIG. 1 , firstly, the entire storage area of ​​the non-volatile storage medium is divided into an integer number of continuous segments, each of which has the same size. Each segment can only be exclusively occupied by one record, and multiple records cannot use the same segment; a record occupies at least one segment, and when the record is relatively long, one record can use multiple segments. Each segment is numbered sequentially. In specific implementation, the numbering can start from 0 from the low address to the high address, and increase sequentially upwards. Among them, the first segment, that is, segment No. 0 is fixedly used to describe the structure of the segment, as a description segment, and the subsequent segments numbered from 1 are used to store records, as a record segment. As a specific embodiment o...

Abstract

The non-volatile information memory managing method includes separating the memory region into several sections as basic units for access operation; numbering the sections successively; defining the initial section as structure describing section and the other sections as information storing record sections. The describing section includes granularity domain and pointer length domain, and the record section includes pointer domain, record name domain format domain and record data domain. The separated memory region is performed the operations of initialization, obtaining record relative data, setting or altering record, deleting record, etc. The present invention makes it possible to utilize memory space flexibly.

Description

technical field [0001] The invention relates to an information storage management method. Background technique [0002] The complexity of modern information systems continues to increase. Software is usually a distributed system, and a large amount of information needs to be stored and queried, such as various software and hardware version information, configuration information, and manufacturing information. These information are generally stored in non-volatile storage media such as EEPROM (electrically erasable read-only memory) and FLASH (flash memory). [0003] At present, the storage of these non-volatile information basically adopts the following two methods: one is to treat all the information as a complete file, each piece of information has no clear location, and the operation of a piece of information must be aimed at the entire file; Another method is to store each piece of information independently, its starting position is fixed at a certain address, the maxim...
