Embodiment Construction

[0012] This embodiment provides a memory data management method, including memory formatting, data storage, and data reading.

[0013] Referring to FIG. 1, the memory format includes: dividing the memory into a boot area, an index area and a data area. The content set in the boot area includes the setting attributes of the data area, the setting attributes of the index area, the size of the data block to be stored (referring to the number of occupied sectors), and the size of the index (referring to the number of bytes). Wherein, the setting attributes of the data area include the starting sector number, the ending sector number, and the number of sectors in the data area; the setting attributes of the data area include the starting sector number, the ending sector number, and the sector number of the index area. quantity. The data area is used for storing data, and the data is composed of several data blocks to be stored, and the size of the data blocks has been defined in t...

Abstract

This invention relates to one memory data management method, which comprises steps of memory formatting and data storing and reading, wherein, the memory formatting is to divide memory into guide area, index area and data area; the guide area content comprises data area set property, index area set property, memory data block size, index size; the data area is to store several memory blocks; index area stores each data blocks relative index; each index content comprises data generation time and sum number.

Description

technical field [0001] The invention relates to a memory data management method, in particular to a data management method in the field of continuously generating a large amount of data and requiring fast reading of data at any time period. Background technique [0002] In the current PC system and embedded devices, the data storage format used for data storage is FAT12, FAT16 developed from DOS system and JFFS, EXT2 and other file systems developed from UNIX and Linux systems. The above-mentioned file system is based on the principle of diversified data management and search, and basically adopts hierarchical tree directory structure management, and stores and queries files through Windows, UNIX, and Linux operating systems. However, in some practical applications, the format of the data to be stored is determined, and its storage and query are mainly indexed by time. For example, when storing, the data is stored in the chronological order generated by the file, and when r...
