Abstract:Most safety-critical avionics systems are defined as "hard real time". That means they must deliver their function within pre-defined deadlines. Missing a single deadline at system level is considered as a failure condition that may be catastrophic. At software level, this is a single failure that must be mitigated with appropriate means to prevent that failure condition. Real-time requirements are addressed in software components by Worst Case Execution Time (WCET) evaluations. Several methods have been explo… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
