Abstract:
|
A reactive system must process inputs from the environment at the speed and with the delay dictated by the environment. The synthesis of reactive software from a modular concurrent specification model generates a set of concurrent tasks coordinated by an operating system. This paper presents a synthesis approach for reactive software that is aimed at minimizing the overhead introduced by the operating system and the interaction among the concurrent tasks. A formal model based on Petri nets is used to synthesize the tasks and verify the correctness of their composition. A practical application of the approach is illustrated by means of a real-life industrial example, which shows the significant impact of the approach on the performance of the system. |
