The Driver Design for SpaceWire Communication Device Based on Embedded Linux

SpaceWire is becoming a popular solution for satellite high-speed data buses, because it is a simple standard that provides great flexibility for a wide range of system requirements. This article introduces the driver design for the SpaceWire communication device based on embedded Linux, including the analysis of the driver structure, the design of the interfaces between the upper and lower layers and the responding strategy for interrupts. In the realization link, we choose a mainstream developing platform and realize a camera capturing system for testing, and analyse the test result.
