An Improved Scheduling Technique for Time-Triggered Embedded Systems

In this paper we present an improved scheduling technique for the synthesis of time-triggered embedded systems. Our system model captures both the flow of data and that of control. We have considered communication of data and conditions for a time-triggered protocol implementation that supports clock synchronization and mode changes. We have improved the quality of the schedules by introducing a new priority function that takes into consideration the communication protocol. Communication has been optimized through packaging messages into slots with a properly selected order and lengths. Several experiments and a real-life example demonstrate the efficiency of our approach.
