（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。-the purpose of this design is by designing and debugging a simple file system, main operation is simulated documents the execution of the order to simulate document management, enable students to the main document commands the substance and the implementation process of a more in-depth understanding, They grasp of the basic method.

Description: 循环冗余校验CRC (Cyclic Redundancy Check)码是由分组线性码的分支而来，其主要应用是二元码字。编码简单且误判概率很低，在通信系统中得到了广泛的应用。循环冗余校验码是属于分组码中的一类重要的线性码，它不仅在理论上具有很好的代数结构，而且其编码和译码可以通过线性移位寄存器很容易地实现。
通过对CRC的分析和基于MATLAB工具的仿真，充分证明了CRC的检错能力很强，编码简单。
-Cyclic Redundancy Check CRC (Cyclic Redundancy Check) code is a linear code from the sub-branch from the main application is the binary code word. Coding is simple and very low probability of miscarriage of justice, in the communication system has been widely used. Cyclic redundancy check code is a block code in one important class of linear code, which not only has good in theory, algebraic structure, and its encoding and decoding of linear shift register can easily realize .

模拟文件系统的操作管理
实现多个进程同时对模拟文件系统进行操作。设计管理程序simdisk的用户访问权限管理。访问模拟文件系统的每个进程都属于某个用户，管理程序simdisk根据其访问权限决定其对模拟文件系统的操作。
对模拟文件系统的操作要求做到：共享读，互斥写。
本设计任务在于学会如何实现信息的安全管理和进程同步。
