文档介绍：【摘要】
的发展和后PC时代的到来,嵌入式系统以其可靠性强、体积小、专用性、成本低等特性得到日益广泛的应用。目前嵌入式系统技术已经成为了最热门的技术之一。与此同时,一个独立的嵌入式系统的功能缺陷也逐渐暴露出来。新一代嵌入计算系统的功能集成和应用模式使之迅速向网络化嵌入计算的方向发展,标准和统一的TCP/IP通信协议是独立于任何厂家的硬件的,因此嵌入环境下的实时网络通信成为嵌入计算技术研究的重点和热点。
实现对远程目标的实时控制,网络技术为基础,开发出一种以ARM920T为硬件平台、Linux为操作系统的网络通信系统,并给出了该系统的硬件结构、软件设计方法,编写程序实现Ping的功能。

ABSTRACT
With the development of and the arrival of Post-PC times, the application of embedded system es popular. Now embedded technology has been the focal point of research. Embedded system has been introduced into more and more application areas for its inherent characteristics such as high reliability, small cubage and low costs. However, defects of a single embedded system have also exposed gradually within appliance. New generation of puting system mostly features at functionality integration and puting, munication protocols is ready and open, the equipment can be the part of the by TCP/IP protocols and promotes more attention and interesting into real-munication between embedded systems.
The use of in order to realize long-term objective of real-time control, this paper, embedded technology and -work technology to develop a hardware platform ARM920T for, Linux for the operating system'munications systems, and give the system's hardware structure, software design implementation Ping function.

引言
后PC时代是一个真实的阶段,而且是一个可以预测的时代。嵌入式系统就是与这一时代紧密相关的产物,它将拉近人与计算机的距离,形成一个人机和谐的工作与生活环境。从某一个角度来看,嵌入式系统可应用于人类工作与生活的各个领域,具有极其广阔的应用前景。
嵌入式系统在应用数量上远远超过了各种通用计算机系统,一台通用计算机的外部设备中就包含了5-
