SpaceWire RMAP Responder (SRR)

The SpaceWire Remote Memory Access Protocol (RMAP) Responder provides a firmware implementation of multiple RMAP targets whose traffic can be monitored, data inspected and activity reported to the user. The SRR's low latency, of the order of 1 microsecond, is comparable with the latency of hardware devices, and does not suffer the delays of software response.

Up to six RMAP response targets are available with 32kBytes of RMAP memory per port, or up to four targets with 64KBytes per port.

Some Diagnostic SpaceWire Interface (DSI) capabilities are available on SRR SpaceWire ports when they are not required to support an RMAP service.

As with all 4Links EtherSpaceLink RG-40x platform products, extra firmware may be purchased to transform the SRR hardware platform to perform other functions such as a Flexible SpaceWire Router (FSR) or a Multi-link SpaceWire Analyzer (MSA) or a full Diagnostic SpaceWire Interface (DSI). This ability to undertake extra duties, and on so many SpaceWire ports, makes the 4Links product range surprisingly cost-effective.
