Embodiment Construction
[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0036] A method for implementing a dual-system file management system, comprising the following steps:
[0037] 1. The memory space management unit implements memory space address management, and records the initial address of the data block and the state of the data block that is being used, needs to be deleted or needs to be allocated through the data block attribute record linked list;
[0038] 2. The storage unit data block control logic unit calls the data block information of the storage space management unit and uses it to query, modify or edit the state of the data block management list to realize data block management;
[0039] 3. The read-write control unit is connected to the storage unit data block contr...

The invention relates to an implementation method of a dual-system file management system, in particular to an implementation method of a dual-system file management system, and belongs to the technical field of multimedia file management. An implementation method of a dual-system file management system comprises the following steps that 1, a memory space management unit implements memory space address management, and records an initial address of a data block which is in use, needs to be deleted or needs to be distributed and a data block state through a data block attribute recording linkedlist; 2, the storage unit data block control logic unit calls the data block information of the memory space management unit and is used for inquiring, modifying or editing the state of the data blockmanagement list to realize data block management; 3, the read-write control unit is connected with a storage unit data block control logic unit to realize asynchronous read-write control or synchronous read-write control on the data block; And 4, the virtual file read-write control unit is located between the read-write control unit and the reliable read-write and non-reliable read-write dual-mechanism read-write control interface layer.
Description
technical field [0001] The invention relates to a management method of a file management system, in particular to a method for realizing a dual-system file management system, which belongs to the technical field of multimedia file management. Background technique [0002] The multimedia file management system includes the classification, storage, search and preview of multimedia materials. The storage of multimedia information is often due to the single storage method of data blocks, and the increase in fragmentation of storage space affects the utilization rate of storage devices, which is easy to reduce the efficiency of reading and writing and the utilization of storage space. utilization rate. Contents of the invention [0003] The present invention aims at the above-mentioned shortcomings, and provides a method for realizing a dual-system file management system. [0004] The technical scheme that the present invention solves the problems of the technologies described...
