逻辑文件系统 meaning in English
logic file system
logical file system
Examples
- This work is focused on the research of the real time response 、 transplantable 、 reducible and configurable of the file system
Deltafile文件系统分为三个实现层次,分别是:虚拟文件系统、逻辑文件系统和块高速缓存。 - In order to support different file systems without perceiving by users , the deltafile provides only a group of api to users
虚拟文件系统将对各种不同的逻辑文件系统的操作和管理纳入到一个统一的框架之中,即同一组系统接口规范。 - There are three layers in deltafile , virtual file system 、 logic file system and buffer cache . besides , deltafile provides the posix api interface
为了对用户透明的实现多种不同文件系统支持的功能, deltafile中采用了虚拟文件系统和逻辑文件系统相分离的体系结构。 - The implementation of deltafile 3 . 0 can be divided into two modules ? real - time file system module and manage module for both facilities and drives . the real - time file system contains four parts ? system call api layer , file node manage layer , virtual file system layer , concrete file system layer , which perform the abstraction of the facility
实时文件系统模块包含系统调用api层、文件节点管理层、虚拟文件系统层、具体逻辑文件系统层四部分,主要完成与设备无关的数据存取接口抽象和各种文件系统标准的实现;设备与驱动管理模块包含逻辑设备管理层、物理设备管理层、设备缓冲区高速缓存层、设备驱动管理层四部分,主要完成外部存储设备管理及其驱动接口抽象功能。 - First it supports the system call interfaces complied with the posix standard , which make convenience to the porting process to delta os for applications . second , delta file 3 . 0 offers the entire supports to the fat logic file system format , and make it suitable in multitasks environment through technique process . once more , delta file 3 . 0 support the flexible virtual file system interface and drive manage interface to make update easier
首先,其系统调用接口遵循posix规范,以便于应用向deltaos进行移植;其次, deltafile3 . 0提供了对fat全系列逻辑文件系统格式(含fat12 、 fat16 、 fat32 )的完全支持,并通过改造将fat这种源于单任务操作系统dos的文件系统标准应用于多任务环境;此外, deltafile3 . 0提供了灵活的虚拟文件系统接口和设备驱动管理接口,便于未来的升级和扩展。
