Abstract

The invention discloses an implementation method of an embedded small real-time file system, which belongs to the technical field of embedded file systems, and comprises the following steps: acquiring a real-time file set to be interacted, the real-time file set comprising a file number, a file identifier, a file occupation and a file type; preprocessing the real-time file set and obtaining a corresponding file coefficient, wherein the file coefficient is a numerical value used for obtaining a mark corresponding to the real-time file set so as to divide the real-time file set; acquiring a data set of sectors in the system, wherein the data set comprises a sector number, a sector identifier, a use space and a sector state; preprocessing the data set to obtain a corresponding fan-dividing value, and matching the fan-dividing value with a preset fan-dividing range to obtain a sector analysis set comprising a first sorting set, a second sorting set and a third sorting set, according to the invention, the technical problem that the real-time processing effect of the file system cannot be improved by dynamically allocating sectors to the file in the existing scheme can be solved.

Description

technical field [0001] The invention relates to the technical field of embedded file systems, and more particularly, to an implementation method of an embedded small real-time file system. Background technique [0002] Embedded file system refers to the module that realizes file access, management and other functions in the embedded system, provides a series of file management functions such as file input and output, and provides file system support for embedded systems and devices; in embedded systems, applications Programs usually need to access information. When the task is running, the task can store a small amount of information in its task stack, but the amount of storage is strictly limited by the memory space, and the information in the memory space will follow the task exit. And disappear, not suitable for storing information to be preserved for a long time. [0003] The invention with publication number CN107908364A and titled as a norflash-based embedded file sys...
