基于ARM的移動(dòng)電話系統(tǒng)設(shè)計(jì)
——硬件電路設(shè)計(jì)
摘要：在很多需要對遠(yuǎn)程數(shù)據(jù)進(jìn)行處理的場合中，無線數(shù)據(jù)采集與傳輸?shù)膽?yīng)用日益廣泛。目前普遍使用的方案是嵌入式CPU+CDMA，由CPU負(fù)責(zé)對采集到的數(shù)據(jù)進(jìn)行運(yùn)算和處理，然后交給CDMA模塊將其發(fā)送給遠(yuǎn)程數(shù)據(jù)中心。
本文深入研究了基于S3C4510B ARM處理器和CDMA模塊的移動(dòng)電話開發(fā)，它是由CPU、FLASH、MEMORY、CDMA、POWER幾個(gè)部分組成，通過Protel99se工具軟件完成了其硬件電路的原理圖設(shè)計(jì)和印制電路版設(shè)計(jì)。
本文實(shí)現(xiàn)了1個(gè)移動(dòng)電話系統(tǒng)的底層硬件設(shè)計(jì)，涉及到的技術(shù)有CDMA技術(shù)、計(jì)算機(jī)技術(shù)、嵌入式技術(shù)等，同時(shí)滿足了系統(tǒng)低成本，低功耗、小體積和移動(dòng)靈活的要求。

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.
Keywords：ARM； CDMA； Hardware Circuit； Printed Circuit Board
