摘　　要：为了开发一个稳定的嵌入式系统,往往采用"增量"式模型,即在功能最简单、最基本的系统的基础上逐渐扩展其功能。这个最简单、最基本的系统就是最小系统。本文介绍了最小系统概念及其设计流程,并对ARM芯片AT91RM9200和实时嵌入式操作系统(RTOS)uc/os-Ⅱ进行了分析,给出了uc/os-Ⅱ移植到AT91RM9200上的实现代码,在此基础上实现了一种基于AT91RM9200和uc/os-Ⅱ的嵌入式最小系统,验证了其可用性。In order to develop a steady embedded system, we usually build it in the incremental model which extends the system function based on a simple, basic one.This basic system is we call Minimum System.This paper describes the common principles and implementation method of minimum system, analyses AT91RM9200 and the RTOS uc/os-Ⅱ, gives the source which for uc/os-Ⅱ tranplanting to AT91RM9200.Then we implement an embedded minimum system based on AT91RM9200 and the RTOS uc/os-Ⅱ and evaluate its feasibility.
