Common SpaceWire software for ESA JUICE instrument payloads: SpaceWire missions and applications, long paper

The common DPU platform for ESA JUICE mission instruments is a hardware and software platform developed by Cobham Gaisler for the scientific instrument payloads of the European Space Agency Jupiter Icy Moons spacecraft. The hardware is based around the GR712RC dual-core LEON3-FT processor with GRSPW2 SpaceWire interfaces. To accompany the JUICE instrument hardware, a flight quality SpaceWire software package has been developed, compliant with ESA ECSS standards for Space Software engineering. The software includes SpaceWire device drivers and protocol support for the SpaceWire CCSDS Packet Transfer Protocol, the Packet Utilization Standard and the SpaceWire Time Distribution protocol.
