Integrated Development Framework for Safety-Critical Embedded Systems

This paper presents an integrated framework for designing and implementing safety-critical embedded systems. The development begins with the specification of the system using the Prelude language. Then there is the compilation step, where the Prelude compiler translates the program into a set of communicating periodic tasks that preserve the semantics of the original program. The necessary schedulability analysis is performed with the SchedMCore analyzer that explores the timing requirements of the periodic tasks concluding about the program schedulability. Finally, the task set can be executed on the singleor multi-core architecture target using the SchedMCore execution environment. We outline the benefits of an integrated development framework by applying it to the task mapping problem, the functional requirement and non-functional requirement co-scheduling problem, and the measurement-based probabilistic timing analysis problem.
