A Review of RASA: Reliability-Aware Scheduling for FPGA-Based Resilient Embedded Systems in Extreme Environments
Aditya Priyadarshi, S. Sumana · International Journal of Research Publication and Reviews · 2025
Field-Programmable Gate Arrays (FPGAs) are a key element of real-time embedded systems for extreme environments such as space and nuclear power plants, where radiation-induced faults like Single Event Upsets (SEU) undermine reliability.Reliability-Aware Scheduling Approach (RASA) suggests a hybrid offlineonline scheduling approach to guarantee task execution in the presence of such faults.This review examines the methodology of Reliability-Aware Scheduling Approach, using partial reconfiguration and preemptive scheduling to achieve a 72% Task Success Ratio with high workloads and fault rates.Compared to conventional methods such as scheduling Triple Modular Redundancy (TMR) and Earliest-Deadline First (EDF), Reliability-Aware Scheduling Approach provides lower overhead and improved efficiency.Strengths are flexibility and new metrics, and weaknesses are simulation-based verification and hard ware specificity.Future work suggests real-world experimentation and wider applicability.This paper sets the context for the applicability of Reliability-Aware Scheduling Approach to rugged systems in extreme environments.
