【摘要】 随着计算机技术逐渐渗透到各类电子产品中，一种实用、高效的计算机系统——嵌入式系统不断展现出它独特的魅力。嵌入式计算机系统专门服务于特定需求，一般要求低成本、低功耗、轻型、高性能、高可靠性及可配置性。本文主要工作是以业界表现出色的ARM处理器(采用ARM7TDMI内核的、三星公司推出的S3C44BOX)及其外围电路为硬件基础，以简明内核式的μC／OS-Ⅱ作为嵌入式操作系统，构建一个嵌入式系统平台，详细的阐述其实现过程。本文共分为四个部分：第一部分简要介绍了嵌入式系统的概念，着重介绍嵌入式系统的体系结构以及发展状况；第二部分从使用ARM芯片的角度，论述ARM7TDMI的体系结构；第三部分以三星公司的S3C44BOX微处理器作为主芯片，以片内外设为基础搭建一个基于ARM7芯片的嵌入式系统硬件平台，并且根据硬件修改相应的Bootloader文件，使硬件能够正常工作；最后，在已有的硬件平台上实现μC／OS-Ⅱ嵌入式操作系统的移植，确保了系统的实时性。本文详细阐述了μC／OS-Ⅱ在硬件平台上的移植过程，并给出了移植过程中修改的与硬件相关的移植代码。更多还原

【Abstract】 With computer technology has trickled down to all kinds of electronic products, a practical and efficient computer system -- Embedded System continuously display its unique charm. Embedded computer. systems specialized services to specific needs and generally requires with low-cost, lightweight, high performance, high reliability and configurability.This paper is based on the industry’s outstanding performance ARM processor (using the ARM7TDMI core, SAMSUNG’s S3C44BOX) and the external circuit as the hardware foundation and in a concise kernel-μC/OS-ⅡEmbedded operating system as a building Embedded System platform. The article detailes description of the research process.There are four parts in this paper:The brief introduction is given to the Embedded System, and a detailed introduction is given to architecture and development of Embedded System in part one.In part two, the paper discussed the ARM architecture from user’s perspective. In part three, we set up a hardware platform of embedded real-time control system based on ARM7 chip. The hardware takes ARM7 mic-processor S3C44BOX of SumSUNG corporation as its chief chip. According to amend the corresponding Bootloader documents of the hardware, we make it work effectively.At last, the software with the embedded real-time platform has made practical the transplant of the embedded operational systemμC/OS-Ⅱonto the hardware platform thereby ensuring the real-time state of the platform. This thesis has elaborated the transplanting process ofμC/OS-Ⅱon the platform, and has given the transplanting code related to the hardware platform.更多还原
