To meet the growing demand of high-speed data transmission between different systems in the spacecraft, the characteristics of SpaceWire bus are studied. A design method of universal SpaceWire bus router for spacecraft is proposed. A standardized SpaceWire bus interface is adopted to support the adaptive routing of multiple SpaceWire interface, realized the “plug and play”. The central controller is used to deal with the advanced protocol algorithm, to support the distributed interrupt management of network. The bus packet can finish the routing by one to one or one to many multicast transmission according to the configuration parameters. The experimental result shows that the router can support up to 18 ports, and each interface can reach 200Mbps. It can meet the needs of most spacecraft SpaceWire networks.
