A system for interfacing Ethernet with SpaceWire comprises a processor including an Ethernet MAC, and a bridge device connected between the processor and a SpaceWire subsystem or network. The bridge device comprises a SpaceWire physical interface that receives SpaceWire data packets, and an Ethernet MAC packet builder that includes digital logic for segmentation of the data packets into Ethernet compatible packet segments. An Ethernet media independent interface receives the packet segments from the packet builder and outputs the packet segments to the Ethernet MAC. The Ethernet media independent interface also receives Ethernet data packets transmitted from the Ethernet MAC. An Ethernet MAC packet extractor receives the Ethernet data packets from the Ethernet media independent interface and includes digital logic for performing reassembly of the Ethernet data packets into SpaceWire compatible data packets, which are sent to the SpaceWire physical interface for transmission to the SpaceWire subsystem or network.
