In the development of embedded software which requires high reliability satisfaction of hard requirements for both computing resource and performance, it is useful to model the system’s behavior under specific computing resources and verify whether the system meet the performance requirements in the design phase of development. So far, we have proposed a method of verifying whether or not they can be scheduled in the worst case by converting the behavioral specification of real-time multi-task distributed systems into an extended Time Petri Nets that can describe fixed priority scheduling and dynamic-priority scheduling such as EDF. Especially in the early phase of the design process, it is useful for low-cost and/or low-power system design to allocate the time budgets among all tasks in order to satisfy its deadline requirement from the input to the output(end -to-end deadline). In this paper, we propose a method to optimize the time budgets of a multi-task behavioral specification using EDF scheduling that have pre-allocated time budgets among all tasks while satisfying the time constraints of the entire system such as end-to-end deadlines, by appropriately modifying the local deadline allocation of each task. . We evaluate the usefulness of the proposed method by applying the proposed method to some example specifications and try to improve its time budgets. |
