Abstract :
This paper investigates the sensitivity of real-time systems running applications under operating systems that are subject to soft-errors. We consider applications using different real-time operating system services: scheduling, time and memory management, intertask communication and synchronization. We report results of a detailed analysis regarding the impact of soft-errors on real-time operating systems cores, taking into account the application timing constraints. Our results show the extent to which soft-errors occurring in a real-time operating system´s kernel impact its reliability
