随着电子技术和计算机技术的发展，微控制芯片功能越来越强大，而嵌入微控制芯片的设备和系统越来越多，从而使得这种技术越来越引人注目。ARM嵌入式处理器是一种高性能、低功耗的RISC芯片。

　　本文将给予ARM做出一个全面的概述。要了解ARM技术及ARM芯片，要从两方面下手：第一是ARM的指令寻址分析；第二是ARM的硬件组成及体系结构分析。

　　该课题就ARM的由来、发展、优势及ARM芯片的体系结构、指令系统、编程方法以及开发工具进行研究。ARM和单片机之间有很大的联系，这里可以运用学习80C51的方法去了解ARM，但是他们之间又有很多的不同之处，这个也是ARM存在的理由。此内容将在最后进行行探讨，找出ARM处理器与80C51芯片之间、ARM处理器各版本之间的联系与区别。以达到通过此次设计掌握开发基于ARM的应用系统的各方面的知识的目的。

-As electronic technology and computer technology, micro-controller chips more powerful, while the embedded micro-controller chip devices and systems more and more, making this technology more and more attention. ARM embedded processor is a high performance, low-power RISC chips.

This article will give a comprehensive overview of ARM made. To learn more about ARM technology and ARM chips to start with in two ways: first, the ARM instruction addressing analysis　second ARM hardware analysis of the composition and architecture.

The subject on the ARM origin, development, advantages and ARM chip architecture, instruction set, programming methods and tools for research. ARM and SCM there is a great link, where the method can be used to study 80C51 to understand ARM, but between them there are a lot of differences, this is also the ARM raison d etre. This content will be OK in the final study to find between the ARM processor and the 80C51 chips, ARM processor, the link between the vario
