【摘要】 随着信息化、网络化、智能化技术的发展，嵌入式技术得到了极大的发展，Linux操作系统以其稳定性好，可靠性高，源代码公开，可剪裁，版权免费等优点，已成为嵌入式领域的一股新兴力量，具有巨大的市场潜力和商业价值。嵌入式处理器种类繁多，要使Linux嵌入式系统在各个领域得到广泛的应用，就必须把Linux嵌入式系统移植到各种处理器平台上，特别是当前主流平台上，并应用于实际的产品。ARM平台是目前应用非常广泛的处理器体系结构，同时也是Linux嵌入式系统移植的一个重点。本文是在对Linux嵌入式操作系统研究和实践的基础上，针对Linux嵌入式系统移植的几个主要核心技术展开。首先详细分析了ARM体系结构的特点并对其进行了系统的总结和归纳；然后详细的分析和阐释了Bootloader重要性、概念、功能、框架，总结和归纳了Bootloader移植关键问题，特点以及移植过程；接下来系统地分析了Linux内核与ARM平台移植相关的内容；最后，结合当前嵌入式系统在Internet中的应用介绍了嵌入式Web服务器的原理与实现。本文不仅建立了一个通用的嵌入式Linux平台，而且实现了支持动态页面的嵌入式Web服务器，这样当需要开发具体的应用系统时，只需要增加业务相关的内容即可。更多还原

【Abstract】 Along with the development of the information, the network and the intelligence, the embedded technology is improved a lot. Because of its stability, open-source, easy-porting and other strongpoint, linux is widely used in embedded field and has huge potation and value in commerce. Because there are many embedded processors, porting linux to a processor is the first step of using linux in embedded area.Among the main embedded processors, ARM is the main stream. So after researching and testing on the linux, the author introduces several key technology about linux porting. First, the author introduces the ARM architecture in detail and systemically sums up the ARM knowledge. Then, the author explains the concept, the characteristic and the functions of bootloader and how to port bootloader. Next, the author expatiates the linux kernel porting on the ARM platform. At last, the thesis introduces the principle and realization of embedded web server with the widely using of embedded Internet.This system not only provides a general embedded linux platform, but also realizes a web server with the ability of dynamic page. So it only need adding some function when developing new application system.更多还原
