The SpaceWire Router IP Core offers a configurable and flexible solution for high data-rate routing switch functionality for on-board satellite networking.

It is based on the SpaceWire protocol, defining bi-directional, full-duplex, serial data communication link, and it is compliant with the SpaceWire standard ECSS-E-ST-50-12C.

The SpaceWire Router IP Core features a parameterized number of SpaceWire ports, based on the SpaceWire CODEC IP Core, and host-side data ports, based on simple asynchronous FIFO interfaces.

The host data ports can be equipped (on request) with Direct Memory Access (DMA) functionality and standard bus interface such as AMBA AXI.

The SpaceWire Router IP Core has been validated and prototyped in ESA project.
