ARM Cortex-M3 Processor Software Development for ARM7TDMI Processor Programmers

要使用低成本的 32位处理器，开发人员面临两种选择，基于Cortex-M3内核或ARM7TDMI内核的处理器。如何做出选择？选择标准又是什么？本文主要介绍了ARMCortex-M3内核微控制器区别于ARM7的一些特点，帮助您快速选择。

This book is for both hardware and software engineers who are interested in the ARM Cortex™-M3 processor. The Cortex-M3 Technical Reference Manual (TRM) and the ARMv7-M Architecture Application Level Reference Manual already provide lots of information on this processor, but they are very detailed and can be challenging for novice readers. This book is intended to be a lighter read for programmers, embedded product designers, systemon- chip (SoC) engineers, electronics enthusiasts, academic researchers, and others who are investigating the Cortex-M3 processor, with some experience of microcontrollers or microprocessors. The text includes an introduction to the architecture, an instruction set summary, examples of some instructions, information on hardware features, and an overview of the processor’s advanced debug system. It also provides application examples, including basic steps in software development for the Cortex-M3 processor using ARM tools as well as the Gnu’s Not Unix tool chain. This book is also suitable for engineers who are migrating their software from ARM7TDMI to the Cortex-M3 processor because it covers the differences between the two processors, and the porting of application software from the ARM7TDMI to the Cortex-M3.

前言不管你是做软件的还是做硬件的，只要相中了ARM的Cortex‐M3处理器，这本书就是为你而写。以前Cortex‐M3的资料只有两个大部头，分别是：《Cort
