说明：  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。 本文旨在通过讨论系统程序设计中的几个基本方面，来说明基于ARM 的嵌入式 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。
(with the traditional 4/8-bit microcontroller compared ARM performance and handling capacity is certainly far ahead, but Correspondingly, the ARM system design complexity and difficulty, compared with the traditional design methods have also greatly improved. This paper aims to discuss procedures for system design of a few basic aspects, to illustrate ARM-based embedded systems developers some of the features and put forward and solved some common problems.)
