Scheduling with Optimized Communication for Time-Triggered Embedded Systems

Abstract

We present an approach to process scheduling for synthesis of safety-critical distributed embedded systems. Our system model captures both the flow of data and that of control. The communication model is based on a timetriggered protocol. We take into consideration overheads due to communication and the execution environment. Communications have been optimized through packaging of messages into slots with a properly selected order and lengths. Several experiments demonstrate the efficiency of the approach. 1
