Example Embodiment

[0043] Example

[0044] Reference figure 1 , The implementation method of the lightweight file system in this embodiment, the implementation method includes: after the embedded device is powered on, the lightweight file system integrated on the embedded device is initialized, and if the initialization fails, the lightweight file system is created. Weight file system; if the initialization is successful, judge whether the lightweight file system exists, if so, wait for the operation instruction and execute the corresponding function; if not, create the lightweight file system, and then wait for the operation instruction and perform the corresponding operation; The operation instructions include external operation instructions received by the lightweight file system and internal operation instructions of the lightweight file system; the external operation instructions include file interception instructions, file renaming instructions, file existence instructions, and file opening in...

Abstract

The invention discloses a realization method for a lightweight file system and relates to the field of electronic data processing. The method includes: after an embedded device is powered on, initialization is performed on the lightweight file system integrated on the embedded device, if the initialization is failed, the lightweight file system is established, if the initialization is successful,whether the lightweight file system exists or not is judged, if the lightweight file system exists, the operation commands are waited and the corresponding functions are executed, if the lightweight file system exists, the lightweight file system is established, the operation commands are waited and the corresponding functions are executed, and the operation commands includes the outside operationcommands received by the lightweight file system and the self inner operation command received by the lightweight file system. The LOG operation mode is adopted to record the file and buffer the data. The mode is easy to be understood, maintained and managed, the frequent operation to the data block is reduced, the read-write speed is smoother, the integral read-write efficiency is improved, andthe service life of an external memory is improved through the LOG operation mode.

Description

technical field [0001] The invention relates to the field of electronic data processing, in particular to an implementation method of a lightweight file system. Background technique [0002] Embedded devices are becoming more and more common in everyday life. The scope of application is also becoming wider and wider. Subsequently, the deficiencies in the data storage and reading process of embedded devices, such as low efficiency, complex system, and difficult maintenance of the code system, are gradually reflected. Although corresponding processing technologies have been used to solve the deficiencies in the data storage and reading process of embedded devices, However, the processing procedure in the prior art is complex and redundant. Contents of the invention [0003] The purpose of the present invention is to provide a method for implementing a lightweight file system, so as to solve the aforementioned problems in the prior art. [0004] In order to achieve the abo...
