【摘要】：自1971年第一颗微处理器的推出,嵌入式系统的概念也随之而来。随着计算机技术、通信技术、网络技术、微电子技术以及半导体技术的迅猛发展,它已经发展成为适用于应用系统有严格要求的、以应用为中心的专用计算机系统。从原始的微型机时代,到独立的单片机时代,再到今天的嵌入式微处理器时代,嵌入式产品已经深深地融入了我们日常生活和工作的方方面面。然而,目前却很少有基于Ad Hoc无线自组网模式、能够自组织形成网络的嵌入式产品。在那些偏远地区,或者是在那些灾区,又或者是在临时仓库,它们要么网络环境很差,要么网络设施被损坏,没有可以直接快速使用的网络。这个时候,基于Ad Hoc无线自组网模式的嵌入式产品就大有作为了本文主要专注于基于ARM的嵌入式终端的硬件设计,通过对硬件电路设计的学习来设计我们所需终端的硬件电路,重点在电路图的设计以及PCB设计,尤其是SDRAM的等长匹配布线设计,通过对成品的测试来改进软硬件设计方案并评测它的性能,然后将我们的设计推向市场产品。本文首先介绍了嵌入式系统的特点及其应用,还简单介绍了它的核心——嵌入式微处理器以及Ad Hoc无线自组织网络。然后利用Protel99Se软件工具设计硬件电路原理以及PCB,最后对硬件设计进行了检测和修改,并对成品做了大量的测试。在硬件原理设计中,掌握嵌入式系统硬件架构并设计基于S3C2440A微处理器的硬件体系,设计终端的原理电路,是本文的一个重点。在硬件PCB设计中,元件数量非常多,所选用的微处理器芯片的管脚数量也非常多并且密集,这使得PCB布局布线,尤其是SDRAM的布线,成为本文的另一个重点。在测试中,由于是基于Ad Hoc的无线手持终端,就必须要进行大量的室内以及室外测试,才能更精确的掌握它的性能。
[Abstract]:With the rapid development of computer technology , communication technology , network technology , microelectronics and semiconductor technology , it has developed into a special computer system which is applicable to the application system .

However , there are few embedded products based on Ad Hoc wireless ad hoc networks that can be self - organized to form a network . In those remote areas , or in those affected areas , or in temporary warehouses , they either have poor network environments or network facilities are damaged , there are no networks that can be used directly and quickly . This time , embedded products based on Ad Hoc wireless ad hoc network mode are great .

This paper mainly focuses on the hardware design of embedded terminal based on ARM . By studying the hardware circuit design , we design the hardware circuit of the terminal we need , focusing on the design of the circuit diagram and the design of PCB design , especially SDRAM . By testing the finished product , the hardware and software design is improved and its performance is evaluated , then our design is pushed to the market product .

This paper introduces the characteristics of embedded system and its application . It also introduces its core _ embedded microprocessor and Ad Hoc wireless ad hoc network . Then the hardware design is tested and modified by Protel99Se software tool .
