2、展方向必然是32位系统。基于ARM体系结构的32位系统占领了32位嵌入式系统的大部分分额，但长期以来，基于ARM体系结构的32位系统仅在嵌入式式系统的高端（通讯领域、PDA）等场合使用，要么以专用芯片的面貌出现，要么以位处理器的庙貌出现，并没有出现性价比高的通用的微控制器。PHILIPS发现了这个空当，推出了性价比很高LPC2000系列微控制器，让更多的嵌入式系统具有32位的处理能力。这也预示着32位系统即将成为嵌入式系统的主流。基于ARM体系结构的芯片在中国推广已经有好几年了，关于ARM的图书也出了不少。关于ARM的图书主要有以下几类：1．关于ARM内核的图书，主要读者是芯片设计者，

3、内容主要是介绍芯片设计的。2．芯片应用类图书，主要是芯片的生产商或代理商编写，主要读者为应用工程师。3．开发板类图书，主要介绍相应的ARM开发板，给应用者一些参考。以上3类图书的侧重点都不是ARM应用开发教学，用于大学本科教学不太适合。为了方便高等院校教学方便，笔者编写了这本教材。不过，因为嵌入式系统牵涉的知识太广，一本教材无法深入论述。为此，笔者还会推出多本被套图书以便学生知识扩展。--1广州周立功单片机发展有限公司Tel:(020)38730916387309173873097638730977Fax:38730925目录第1章嵌入式系统概述····················
