ARM® 系列微处理器作为全球16/32 位RISC 处理器市场的领先者，在许多领

域内得到了成功的应用。近年来，ARM 在国内的应用也得到了飞速的发展，越

来越多的公司和工程师在基于ARM 的平台上面开发自己的产品。

与传统的4/8 位单片机相比，ARM 的性能和处理能力当然是遥遥领先的，但

与之相应，ARM 的系统设计复杂度和难度，较之传统的设计方法也大大提升了。

系统程序开发的一些特点，并提出和解决了一些常见的问题。-ARM ? family of microprocessors as the world s 16/32-bit RISC processors, the market leader in many areas has been successfully applied. In recent years, ARM applications in China has been rapid development, more and more companies and engineers in the ARM-based platform to develop their own products. With the traditional 4/8-bit MCU compared, ARM s performance and processing power is far ahead, but corresponding, ARM system design complexity and the difficulty of the design than the traditional approach also greatly enhanced. This paper aims to discuss the system design through a few basic aspects, to illustrate the ARM-based embedded system development some of the features and make and solve some common problems.
