RC64: Space Manycore Enabled by SpaceWire & SpaceFibre

RC64 rad-hard manycore DSP/ML processor employs the Space-oriented SpFi and SpW communication protocols. It is the only known Space product fully based on these two standards. RC64 employs six SpaceWire links and twelve high-speed SpaceFibre links. This connectivity facilitates modular complex systems comprising tens and more processors spanning multiple PCBs and multiple enclosures for all Space missions. Small and reliable, thermal-cycle resilient chip packages are enabled. Systems for satellite communications, Earth observation, remote sensing, storage, cloud computing, autonomous spacecraft and instruments and more are being designed and implemented. Design considerations and challenges are described, and future versions are described.
