Abstract

Real-time operating systems are often utilized to simplify the design of embedded time/safety-critical applications. However, real-time embedded systems are sensitive to transient and other faults, each of which can lead to various errors at different system levels and can potentially result in the system failure. In the previous papers, a real-time kernel sensitivity to soft-errors was studied and the errors being induced were classified. In this paper, sensitivity to transient, permanent and firmware faults is analyzed on basis of data gathered from series of experiments over the uC/OS-II kernel. During each of the experiments, various dependability techniques (N-version programming, control-flow checking, watchdog tasks and processing of pairs) - and their combinations - were implemented into the kernel and various faults were injected into the kernel in order to study impact of their effects to both response timeliness and behavior correctness of the system.
