摘　　要：为使带有现场可编程门阵列(Field Programmable Gate Array,FPGA)的嵌入式系统具有远程在线更新能力,在硬件透明编程模型的基础上,应用以太网通信协议,设计并实现了具有回读功能的远程动态可重构嵌入式系统。同时研究了动态可重构的实现方法,详细讨论了硬件平台架构与软件设计流程。该技术使系统具有了远程动态修改、回读硬件逻辑的能力,极大地方便了硬件平台在后期的维护和升级。This paper designs an embedded system with readback and remote and dynamic reconfiguration capabilities based on reconfiguration technology,Ethernet communication technology and hardware transparent programming model.It discusses the implement methods,provides the hardware platform and the program flow of software to implement configuration process,and proposes some prob-lems to be solved.Based on this technology,the system has such capabilities as remote dynamic modification and readback hardware log-ic,which are convenient for later maintenance and upgrade.
