前言
ARM（Advanced RISC Machines）是微处理器行业的一家知名企业，该企业设计了
大量高性能、廉价、耗能低的 RISC 处理器、相关技术及软件。技术具有性能高、成本
低和能耗省的特点，适用于多种领域，比如嵌入控制、消费/教育类多媒体、DSP 和移
动式应用等。
ARM 将其技术授权给世界上许多著名的半导体、软件和 OEM 厂商，每个厂商得到的
都是独一无二的 ARM 相关技术及服务,利用这种合作关系，ARM 很快成为许多全球性 RISC
标准的缔造者。
目前，ARM内核的微处理器正在我国迅速普及和发展，许多朋友已经开始着手学习、
研究和利用这类芯片进行商品化设计，为了帮助广大朋友更快的学习和使用这种先进的
技术，广州周立功单片机发展有限公司(http://www.zlgmcu.com)曾面向大众推出了一
款EasyARM试验板,本文的大部分内容来自此款试验板的配套教材--《ARM微控制器基
础》，并且得到周立功正式授权。本文主要是针对ARM7TDMI(-S)内核，经本人重新排版，
制作成PDF格式，便于大家查阅和使用。
本文仅仅用于大家的学习和研究使用，由于本文的原因造成元器件的损坏、设计方
案的缺陷与失败等一切损失，概不负责。
感谢周立功老师为我们提供了丰富的资源并亲自审阅了本文，感谢单片机学习网
(http://www.mcustudy.com)为我们提供了交流和学习的空间，感谢我的女友对我这项
工作的支持，她自己放弃了大量的业余时间帮我录入和排版。
由于时间仓促，本文难免会存在不当之处，欢迎大家来信(email:mcu8031@163.com)
或在网上(QQ:57523799)批评指正和交流，以便在今后的版本加以更正，也希望大家能
把自己在工作中的心得体会和经验拿出来，和众多的同行及爱好者交流，共同提高，一
起进步。
