摘　　要：本文的研究对象是SpaceWire网络层协议.通过分析欧空局(ESA)SpaceWire产品和美国航空航天学会(AIAA)SpaceWire专题年会成果,概述了国内外SpaceWire技术特别是其组网技术的发展和应用现状.根据欧空局最新版规范ECSS-E-ST-50-12C,详细分析了SpaceWire网络层结构,包括路由方式和寻址方式,其中重点阐述了蛀洞路由器、区域逻辑寻址的工作原理.在此理论基础上,给出了基于FPGA单芯片、以交叉矩阵为核心、带有通用主机接口的无阻塞4端口SpaceWire路由器设计方案.本文最后还通过比较SpaceWire与Ethernet协议的异同,论证了二者在高层协议和应用软件方面的兼容性,得出结论:可以将Ethernet网络的软件资源移植到SpaceWire上.SpaceWire production of ESA and AIAA is analyzed, and the actuality of SpaceWire technique development and application, especially about the network organizing, is reviewed. The architecture of SpaeeWire network is detailed according to the latest standard ECSS-E-ST-50-12C mainly about the algorithms of routing and addressing. The operational principles of wormhole routing and regional logical addressing are emphasized. The design scheme of a FPGA-based non-blocking, 4-ports SpaceWire router with a crossbar matrix as its core is presented, which has a general host control interface. At last, the compatibility of the higher layers protocol and application software between SpaceWire and Ethernet is discussed by comparing their protocols. It is concluded that the software resource of Ethernet can be transplanted to SpaceWire.
