Description
The increasing requirements in cost and performance for the NewSpace approach combined with the radiation tolerance capability demanded in space systems have created the need to develop high-performance, low-cost, fault-tolerant systems for space missions. Unfortunately, although radiation-hardened devices meet the radiation tolerance requirements, these devices may not always meet performance and cost requirements. In contrast, commercial off-the-shelf devices may meet performance and cost requirements, but they are radiation susceptible, so they do not meet safety requirements. To achieve a platform that meets these performance, cost, and safety requirements, this work proposes a novel reconfigurable fault-tolerant and open-source processing system for space applications. On the hardware side, the system combines a RISC-V processor suitable for space environments (NOEL-V) with ARTICo³, a reconfigurable multi-accelerator architecture that can dynamically trade-off between computing performance, energy efficiency, and fault-tolerance. On the software side, the host processor runs under RTEMS real-time operating system. To enhance fault tolerance, the system is reinforced by a hierarchy of heterogeneous configuration memory scrubbers.
