  • 本设计的目的是通过设计和调试一个简单的文件系统

    本设计的目的是通过设计和调试一个简单的文件系统,主要是模拟文件操作命令的执行,来模拟文件管理,使学生对主要文件操作命令的实质和执行过程有比较深入的了解,掌握它们的基本实施方法。具体要求如下: (1) 设计一个支持n个用户的文件系统,每个用户可拥有多个文件: (2) 采用二级或二级以上的多级文件目录管理; (3) 对文件应设置存去控制保护方式,如“只能执行”、“允许读”、“允许写等”; (4) 系统的外部特征应接近于真实系统,可设置下述文件操作命令: 命 令 功 能 命 令 功 能 Create 建立文件 Read 读文件 Open 打开文件 Write 写文件 Close 关闭文件 Copy 复制文件 Delete 撤消文件 Directory 查询目录 (5) 通过键盘使用该文件系统,系统应显示操作命令的执行结果。

  • (1) 给定一段符合Pascal子集语法的语言

    (1) 给定一段符合Pascal子集语法的语言,能成功转换成C语言; (2) 一个简单的说明文档; (3) 2007.7.14之前上传到ftp:// C07:C07@10.11.3.71/upload,用学号建立自己的目录; (4) (可额外加分5分)若有出错处理功能,请在说明文档中写明可以处理哪几项错误。 注意事项: (1) 两人一组 (2) 可以使用词法、语法自动生成工具,windows下有Flex,Bison,Linux下有Lex,Yacc,Java的有Jlex,JavaCC,ANTLR等 (3) 不用考虑Pascal和C的关键词不同问题,即Pascal子集语言中假设不出现int,for等作为变量标志符 (4) read()和write()可用由scanf(),printf()等组成的语句转换。 (5) 如果有疑问可以发信给我 xpqiu@fudan.edu.cn.

  • FLASH文件系统的源码

    FLASH文件系统的源码,Flash memory is a nonvolatile memory, which allows the user to electrically program (write) and erase information. The exponential growth of flash memory has made this technology an indispensable part of hundreds of millions of electronic devices. Flash memory has several significant differences with volatile (RAM) memory and hard drive technologies which requires unique software drivers and file systems. This paper provides an overview of file systems for flash memory and focuses on the unique software requirements of flash memory devices.
