QFDR-an integration of Quadded Logic for modern FPGAs to tolerate high radiation effect rates

摘要

For new device generations simply replicating complete systems in TMR manner may not be sufficient anymore. This especially applies to harsh environments, such as space applications, as higher failure rates may disturb a second instance before the faulty first one recovers. We focus on SEU mitigation challenges in nano scale reconfigurable architectures which can result in crucial situations. Our approach which is called Quadruple Force Decide Redundancy (QFDR), transforms the classical idea of Quadded Redundancy on Logic Gates to a technological view based on FPGA architecture primitives like LUTs.
