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...
