摘 要 <br>

在以计算机技术、通讯技术相结合的信息时代的快速发展和互联网的广泛应用的形势下， <br>

3C（Computer、Communication、Consumer）合一的趋势已经形成，其结果必然就是将计算 <br>

机工业的中心从计算产品转移到信息产品，从而出现信息电器的概念。在信息电器的应用 <br>

开发领域，由于需要的功能不断的增加，嵌入式系统也就将成为软件业的新宠儿。同时在 <br>

计算机本身的领域里面，微型化和专业化成为了发展的新趋势，同样也需要嵌入式系统的 <br>

支持。因此，研究与嵌入式系统有关的关键技术——嵌入式操作系统有着相当重要的实际 <br>

意义。 <br>

本论文详细论述了作者在学士学位论文工作期间在基于Linux的嵌入式操作系统研究工作领 <br>

域里所做的研究和实践，主要围绕着论证使用Linux改造成符合嵌入式操作系统条件的几点 <br>

要求展开讨论。首先，我对嵌入式系统的概念和信息电器的概念做出表述，并且说明Linu <br>

x的特点、发展状况河开发环境。紧接着，分三个方面论述使用Linux进行嵌入式系统开发 <br>

的便利，包括Linux的实时变种——RTLinux的原理、实现方案和编程方法；Linux网络设备 <br>

驱动程序的分析和利用到嵌入式系统中的方案；实现Linux和RT Linux的内核在线调试环境 <br>

的途径。其中还讲到了如何利用现有的工作设计出一个嵌入式Linux系统。最后，针对现有 <br>

的工作，提出进一步开发出完整的、具有市场竞争力的产品提出开发展望。 <br>

Abstract <br>

With the development of Computer technology and Communication technology in In <br>

formation times and the board application of Internet, it is clear that 3C (Co <br>

mputer, Communication and Consumer) will converge in the near future which wil <br>

l lead the focus of Computer Industry from the Compute product to Information <br>

product. It is the concept of Information Appliance. In the application and de <br>

velopment field of Information Appliance, Embedded Operating System will be th <br>

e most favorite thing in Software Development field. At the same time, in the <br>

field of computer science itself, the micromation and specialization is the ne <br>

w direction of  the computer world. It also want the support of Embedded Syste <br>

m. So, the research of the key technique of embedded system——Embedded Operat <br>

ing System is the most important thing. <br>

  <br>

This thesis presents the author’s work in research of the Linux-based Embedde <br>

d Operating System for his bachelor degree. Most of the thesis focus the requi <br>

rement of transforming  Linux to Embedded System. Firstly, it describes the co <br>

ncepts of embedded system and Information Appliance, and presents the characte <br>

ristic and development environment of Linux. Then describe three aspects of th <br>

e key techniques of using Linux as the development tools of Embedded system In <br>

cluding the real-time variant of Linux——RT Linux and it’s principle, implem <br>



entation and the programming; the network coding in Linux kernel and the analy <br>

sis of Linux network device drivers and the online debug environment of Linux <br>

Kernel and RTLinux Kernel. I have also involved the implementation of embed Li <br>

nux/RTLinux in a floppy to simulate the embedded environment. In the last part <br>

 of this thesis, I give the suggestions and prospect of the development of a m <br>

ature embedded system which have the most competition ability in China market ba <br>

e on the current work. <br>
