Model-based Design for Real-time Software

Model-based design is a novel approach for real-time embedded software. According to the demand of application in the data validity interval, real-time scheduling model directly can be derived based on the producer-consumer model. The precedence constraint problem in the producer-consumer model is solved by the mixed system of the time-triggered tasks and the event-triggered tasks. The model relaxes the deadline restriction for the task period, while preserving the synchronous computation semantics. Key Words: real-time scheduling;model-based design;precedence constraint
