Real-Time Scheduling Techniques for Implementation Synthesis from Component-Based Software Models

摘要

We consider a class of component-based software models with interaction style of buffered asynchronous message passing between components with ports, represented by UML-RT. After building a logical software model, it is necessary to synthesize a multi-threaded implementation that runs on a given target hardware platform and satisfies timing constraints. Commercial code generators generate functional code, but ignore concurrency and timing issues. In this paper, we compare alternative multi-threading strategies for implementation synthesis from this class of software models, and describe real-time scheduling analysis techniques that are useful during design space exploration for implementation synthesis. We use the elevator control application to illustrate our analysis techniques.
