The Remote Memory Access Protocol (RMAP) IP Core provides RMAP packet handling which is fully compliant to the ECSS-E-ST-50-52C standard. RMAP provides a means of reading and writing to memory in remote units over a SpaceWire or SpaceFibre network. STAR-Dundee provides two flexible RMAP IP cores: the RMAP Target which provides the RMAP interface for the unit being written to or read from, and the RMAP Initiator which provides a co-processor to send RMAP read or write commands and handle any replies or errors. The packet interface is AXI4-Stream supporting both the SpaceWire and SpaceFibre interface and router IP cores. It uses an AMBA bus interface for system memory transfers.
