Description / Outline

Real-Time Systems – The term real time is one of the most misused terms in computer science and is commonly considered in various context, for example, real-time games, real-time video streaming, real-time communication. In fact, real-time systems are not characterized by being considerably fast but by their connection to the real world and its real time. The goal of real-time systems is to provide results of functions within deadlines. Depending on the point of view, real-time systems are usually embedded systems or cyber-physical systems, when emphasizing the aspect of controlling physical objects. The research field of real-time systems spans from system-software topics (such as real-time operating systems) to the resource analysis of real-time systems. Regarding the analysis of real-time systems, the research field addresses the determination of the worst-case execution-time bounds in order to meet timeliness.
