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。

This code sample shows how to write a simple Javadoc 1.2 Doclet. Used with Javadoc, it can generate a Unix-style inverted index for a set of Java classes, with links to real Java API documentation. Includes directions and source code. This doclet requires JDK 1.2.1 or later, it will not work with JDK 1.1

The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowledge of the elements of arithmetic as they exist on a computer. That conclusion and this book are the result of a long and frustrating search for information on writing arithmetic routines for real-time embedded systems. With instruction cycle times coming down and clock rates going up, it would seem that speed is not a problem in writing fast routines. In addition, math coprocessors are becoming more popular and less expensive than ever before and are readily available. These factors make arithmetic easier and faster to use and implement. However, for many of you the systems that you are working on do not include the latest chips or the faster processors. Some of the most widely used microcontrollers used today are not Digital Signal Processors (DSP), but simple eight-bit controllers such as the Intel 8051 or 8048 microprocessors.

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over)

Avalon Interface Specification,The Avalon interface specification is designed to accommodate peripheral development for the system-on-a-programmable-chip (SOPC) environment. The specification provides peripheral designers with a basis for describing the address-based read/write interface found on master and slave peripherals, such as microprocessors, memory, UART, timer, etc.
