The Research of FPGA-based Software Processing TT&C System

介绍了一种基于多台分布式服务器结构的软件无线电测控系统,系统采用可编程门阵列（field programmable gate array,FPGA）对前端中频信号进行协处理,采用对FPGA远程动态配置,使得系统具有高度软件化的结构,采用PCI-E总线进行数据采集和网络实时数据交换,提高数据传输效率;分析了软件化测控的特点,并对FPGA协处理采用的相关技术进行了详细讨论;最后对系统进行了构建,并从处理实时性方面分析了系统的可行性。

This paper introduces software tracking telemeter and control（TT＆C） system based on FPGA, system characterized by its software configuration. System is applied on high performance PC servers, sampled data is transmitted through PCI-E bus, which can greatly improve data transmit speed. A remote system upgrade technique is used in FPGA coprocessor board. Finally a realistic FPGA coprocessor is designed to illuminate that system can accomplish receiving and transmitting of TT＆C intermediate frequency signals.
