毕业论文 PAGE 毕业论文 【摘要】 后PC时代是一个真实的阶段，而且是一个可以预测的时代。嵌入式系统就是与这一时代紧密相关的产物，它将拉近人与计算机的距离，形成一个人机和谐的工作与生活环境。从某一个角度来看，嵌入式系统可应用于人类工作与生活的各个领域，具有极其广阔的应用前景。ARM微处理器及技术的应用具有广阔前景与深远意义，已经成为上述领域的一项共识。 本文主要通过对ARM9体系结构的描述，使用MULTI-ICE软件仿真器对嵌入式数码管进行模拟设计，通过ARM指令、thumb指令和C语言的编程，使用IIC总线读写ZLG7290LED驱动器，在数码管上以“反显”的方式递增显示“0000”到“9999”。 以此达到设计目的，使得自己嵌入式系统开发应用能力得到提高，为自己的可持续性发展奠定基础。 【关键词】：嵌入式系统，ARM9体系结构，数码管扫描电路。 ABSTRACT Post-PC era is a real stage, but are a prediction of the times. Embedded systems is closely related with the product of the times, it will narrow the distance between man and computer, forming a harmonious human-computer work and living environment. From a certain perspective, the embedded system can be applied to human work and all areas of life, an extremely wide application prospect. Based on this, ARM microprocessor and technology have broad and far-reaching prospects has become a consensus of the above-mentioned fields.  In this paper, through the ARM9 architecture description, use the MULTI-ICE emulator software for embedded digital tube to simulate the design, through the ARM instruction, thumb instructions and C programming language, use the IIC bus read and write ZLG7290LED drive, in the digital tube in order to anti-significant incremental manner show 0000 to 9999. Designed to achieve, making their own development and application of embedded systems enhance capacity for their own lay the foundation for sustainable development. 【KEY WORD】: Embedded systems, ARM9 architecture, digital tube scanning circuits. 目 录 一、 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc196303662 引言 1页 HYPERLINK \l _Toc196303665 二、ARM9体系结构的介绍 3页 （一）ARM9硬件结构 HYPERLINK \l _Toc196303666 3页 （二）ARM指令体系 HYPERLINK \l _Toc196303667 6页 （三）ADS1.2编译软件介绍 HYPERLINK \l _Toc196303668 7页 HYPERLINK \l _Toc196303670 三、基于ARM920T的IIC数码管扫描电路系统设计 9页 （一）LED显示原理 HYPERLINK \l _Toc196303671 9页 （二）IIC总线传输实现 HYPERLINK \l _Toc196303672 10页 (三) 软硬件实现 HYPERLINK \l _Toc196303673 12页 HYPERLINK \l _Toc196303677 四、结束语 17
