摘　　要：在多通道广域电磁接收机中,高性能嵌入式系统的应用,将有利于提高其智能化控制水平,更好地满足资源野外勘探中在功耗、信号处理能力和实时响应能力等方面的要求。文章在分析嵌入式系统和嵌入式处理器的基础上,选取了德州仪器高性能嵌入式ARM Cortex-A8微处理器AM3517作为核心,阐述了AM3517处理器的基本工作原理和ARM嵌入式系统硬件的设计方法,结合广域电磁法的应用需求,设计了基于AM3517的核心主控电路。使用ORCAD高性能电子设计软件,详细解析了硬件平台设计过程,所设计的平台配置了存储系统及外围硬件等设备,完成了整个核心系统的硬件电路原理图和PCB板设计。In the multichannel wide-field electromagnetic receiver,using the high-performance embedded system is good for improving the intelligence and automation control level,and then better satisfying the demands on the power consumption,signal processing and real-time responding ability when working in field exploration. Based on the analysis on embedded system and embedded processor,the Texas Instrument high-performance embedded ARM Cortex- A8 microprocessor AM3517 was chosen as the core. This paper presents the basic working principle and design method for ARM embedded system hardware.Combined with applying needs of wide-field electromagnetic method,the core system on AM3517 was designed. Using the ORCAD high-performance EDA software,this paper analyzes the design process of hardware platform in detail,which was configured with memory system and peripheral equipments.
