基于ARM7的S3C44B0最小系统 设计报告 小组成员：林涛、李丽华 指导教师：徐阳 2011年10月2日近年来随着电子技术、计算机技术的迅速发展，嵌入式系统逐步广泛的应用于工业控制、汽车电子、通信和家用消费类电子等领域，越来越与人们的生产生活紧密相连。随着嵌入式系统的应用范围越来越大、功能越来越复杂，在很多嵌入式系统中已经广泛采用了实时多任务操作系统(RTOS)。嵌入式操作系统的移植工作成为实现高性能嵌入式应用系统的基础。 本是 “”前期工作的一部分，完成了。首先介绍了嵌入式实时操作系统的然后介绍了基于三星公司微控制器的最小系统硬件平台的设计工作。在介绍了最小系统的组成、各主要芯片特点的基础上详细介绍了各模块的功能、作用。然后详细介绍了操作系统在最小系统上的移植过程。The minimum system design based on ARM7 S3C44B0 Abstract In recent years along with the electronic technology, the rapid development of computer technology, embedded system has widely used in industrial control, automotive electronics, communications and home consumer electronics and other fields, and the increasing of peoples production and life are closely linked. With the development of embedded system application scope is more and more big, function more and more complex, in many embedded systems have been widely used in the real time multi task operating system ( RTOS ). Embedded operating system transplant to achieve high performance of embedded application system based on. The design is based on ARM7 S3C44B0 minimum system design of early part of work, completed the minimum each function module of the system selection, system of the general principles of map and PCB plate drawing with kernel transplant preparatory work. The report introduced the first ARM7 based embedded real time operating system selection and characteristics. The Samsung S3C44B0 MCU minimum system design of hardware platform. After the introduction of the minimum system composition, the main chip characteristics based on the detailed introduction of the module function, role. And then described in detail Linux operating system in the transplant process of minimum system. Keyword: ARM7; S3C44B0; Linux system. 目录 摘要 2 Abstract 3 第1章 绪论 5 1.1 系统选择 5 1.2 系统简介 5 第2章 系统设计概述 7 2.1 ARM处理器概述 7 2.1.1 存储数据类型和存储格式 7 2.1.2存储器层次简介 8 2.1.3 ARM7TDMI处理器核的硬件接口 9 2.2 S3C44B0概述 13 2.2.1 S3C44B0概述 13 2.2.2 S3C44B0X 特性 14 第3章 最小系统硬件设计 19 3.1 电源电路 19 3.2 复位电路 20 3.3 时钟电
