毕业设计（论文）-基于ARM的应用开发—LCD显示波形.doc

摘要
随着现代计算机技术的飞速发展和互联网技术的广泛应用,从PC时代过渡到了以个人数字处理、手持个人电脑和信息家电为代表的3C(计算机、通信、消费电子)一体的后PC时代。后PC时代里,嵌入式系统扮演了越来越重要的角色,被广泛应用于信息电器、移动设备、网络设备和工控仿真等领域。
本文讨论了基于ARM微处理器和嵌入式系统的应用开发,主要以波形采集、LCD显示和嵌入式系统μC/OS-II为主要研究对象。描述了三星S3C44B0X微处理器及μC/OS-II实时操作系统的特点,搭建了一个以S3C44B0X处理器为核心的通用嵌入式系统平台,并在此平台基础上实现了LCD显示波形、GUI绘图、多任务系统等典型应用。对ARM微处理器和嵌入式系统的进一步教学和研究开发有一定的指导价值。

Abstract
With the development of the puter technology and the widely application of the technology, We transited from the PC time to the latter PC time which is taking individual digital processing,grasping the puting and the information electrical appliances as representative's 3C (computer, correspondence, expense electron) a body .In the latter PC time, the inserted type system which acts the more and more important role, is widely applied in the information electric appliance, the mobile equipment, work equipment and the labor controls domain and so on.
This article discussed the application development based on the inserted type system and the ARM microprocessor, mainly by profile gathering, LCD demonstrated and the inserted type system μC/OS-II is the main research object. Described the Sumsang S3C44B0X microprocessor and The characteristic of the real-time operating system μC/OS-II. build a general inserted system platform take the S3C44B0X processor as the core, and has realized LCD model application, GUI cartography, multi- duties system and so on in this platform foundation. The further teaching and the research development of the inserted type system and the ARM microprocessor has the certain instruction value.
Keywords:ARM microprocessor The inserted type system μC/OS-II GUI cartography Multi- duties system
