Quasi-static scheduling for concurrent architectures

Abstract

We present a synthesis approach for reactive systems that aims at minimizing the overhead introduced by the operating system and the interaction among the concurrent tasks, while considering multiple concurrent execution resources. A formal model based on the notion of scheduling of Petri nets is used to perform the synthesis. We show how the notion of projections of a schedule for the complete system onto the components implemented on separate resources is essential to define the correctness of the partitioned schedule.
