In recent years, there has been a growing demand for High‑Performance Spaceflight Computing (HPSC) to support next‑generation space missions characterized by increasing autonomy, heterogeneous sensor networks, and the integration of onboard artificial‑intelligence algorithms. The aim is to develop autonomous and efficient systems that are able to support remote autonomous operations, on-board data processing for deep space missions. However, adopting such systems in aerospace and avionics requires significant safety and reliability challenges as these safety‑critical applications must ensure continuous operation even in the presence of radiation‑induced effects that can affect electronic devices and alter system behavior. This work proposes an efficient, reliable, and scalable computing architecture based on a two-node core implemented on ZCU102 FPGA boards connected by a single optical‑fiber link.
