Project

High-Performance Fault-Tolerant Computing for Harsh Environments

Today, spacecrafts require an increasing amount of computing power for a next generation of communication systems and intelligent space missions. In the near-future many systems will rely on complex algorithms and AI which require massive amounts of on-board processing power. However, high performance computers in ground applications are sensitive to radiation-induced errors. The main goal of this project is to develop a new novel error tolerant processor with improved execution performance without compromising reliability due to radiation.The novel idea in this project is a new soft-error mitigation technique that is based on an error detection mechanism instead of an error correcting implementation at the core of the processor. By only detecting the occurrence of an error and re-playing faulty instructions, the additional overhead of soft-error mitigation techniques to the performance is significantly reduced.
