REMPRO: Reconfigurable Modular Processor Invited Paper

In space applications, the electronic systems that drive mission-critical operations face unique challenges due to harsh environments characterized by temperature variations and cosmic radiation. The reliability and resilience of electronic systems become paramount in ensuring the success of space missions, where the slightest hardware failure can have profound consequences. To address these challenges, this paper introduces REMPRO, a robust processing system designed specifically for space applications. REMPRO's architecture embodies modularity at both the system and device levels, utilizing multiple chained Field-Programmable Gate Arrays (FPGAs), each equipped with a triple modular redundancy (TMR) processor to enhance reliability and fault tolerance. The system is distinguished by having only one active device at a time and the ability to reconfigure autonomously in case of faults, transferring the current state to the subsequent processor to ensure continuity in mission execution and consequently enhance overall system availability.
