A hybrid and reconfigurable edge node computer using SpaceWire and SpaceFibre

We developed a hybrid and reconfigurable edge node computer with SpaceWire and SpaceFibre interfaces, which is called Space Cube ^® mk4, as a digital development platform for a model-based development process. Dynamically reconfigurable processors (DRPs) are integrated with conventional microprocessors and a field programmable gate array (FPGA). In addition to artificial intelligence processing capabilities of DRPs, interfaces for general purpose graphics processing units (GPGPUs) and vector processing units of super computers are also incorporated. The processing signals generated by DRPs are transferred in wire-rate via SpaceWire and SpaceFibre interfaces. A breadboard model (BBM) of Space Cube® mk4 weights under 500 g, and a satellite system simulator is under development using the BBM. We report the development result of the BBM in this paper.
