基于ARM的移动电话系统设计
——硬件电路设计

摘要：在很多需要对远程数据进行处理的场合中，无线数据采集与传输的应用日益广泛。目前普遍使用的方案是嵌入式CPU+CDMA，由CPU负责对采集到的数据进行运算和处理，然后交给CDMA模块将其发送给远程数据中心。
本文深入研究了基于S3C4510B ARM处理器和CDMA模块的移动电话开发，它是由CPU、FLASH、MEMORY、CDMA、POWER几个部分组成，通过Protel99se工具软件完成了其硬件电路的原理图设计和印制电路版设计。
本文实现了1个移动电话系统的底层硬件设计，涉及到的技术有CDMA技术、计算机技术、嵌入式技术等，同时满足了系统低成本，低功耗、小体积和移动灵活的要求。

The Design of Mobile System based on ARM
——Hardware Circuit Design
 
Abstract：In the circumstance of processing remote data, wireless data collection and transmission is used widely. Nowadays the commonly scheme is embedded CPU and CDMA, in which CPU collects data and deals with it, and CDMA module transfers data to remote center.
Thesis studies profoundly the hardware circuit design of mobile system, which is based on S3C4510B ARM processor and CDMA module. The system is composed of CPU、FLASH、MEMORY、CDMA and POWER modules. Thesis also introduces the procedure of designing the schematic document and Printed Circuit Board with the Protel99se tool software.
Thesis implements the hardware circuit of mobile system. It adopts many advanced technologies such as CDMA technology, computer technology and embedded technology, and meets the demands of lower cost, lower power consuming, smaller size and higher flexibility.
