Analyzing the real-time behaviour of deeply embedded event driven systems

Abstract

Most embedded control systems react on events in the real world by reading sensors and controlling actuators in real-time. This general behavior can be directly mapped onto event-driven systems in a natural and straightforward manner for a large variety of applications. Further real-time analysis and profiling on the same level of abstraction is possible for event-driven systems. This significantly helps developers of deeply embedded real-time applications. In this paper we introduce simulative profiling concepts and static analysis basics for the real-time analysis of event-driven systems. Furthermore we present a prototype analysis tool for the REFLEX operating system that integrates real-time analysis into the software development cycle.
