SpaceFibre Routing Switch IP Implementation in Radiation-Tolerant FPGAs 630.43 KB
SpaceFibre is a technology specifically designed for use in spaceflight applications that provides point-to-point and networked interconnections at Gigabit rates with Quality of Service and Fault Detection, Isolation and Recovery. SpaceFibre is backwards compatible with SpaceWire, allowing existing SpaceWire equipment to be incorporated into a SpaceFibre network without modifications at packet level.
In this work we present the SpaceFibre Routing Switch IP Core developed by STAR-Dundee and its subsidiary STAR-Barcelona. This IP Core is fully compliant with the SpaceFibre standard – including the Network ayer – thus providing a cornerstone technology necessary for future on-board data-handling systems. We also describe the capabilities and performance of the Routing Switch design. The design provides a highly flexible router comprising a number of ports and a fully configurable, non-blocking, high performance, routing switch. Finally, the implementation results of this Routing Switch IP in radiation-tolerant FPGAs re summarized and discussed. The Routing Switch IP has been carefully implemented to optimise its performance and minimise its footprint on radiation-tolerant FPGAs (e.g. RTG4, Virtex-5QV or KU060) and ASICs.
The SpaceFibre Routing Switch completes the set of essential SpaceFibre technology, providing a missing building block for the next generation of on-board data-handling systems.
