Abstract

The synchronous model of computation together with a suitable execution platform facilitates system-level timing predictability. This paper introduces an algebraic framework for precisely capturing worst case reaction time (WCRT) characteristics for Esterel-style reactive processors with hardware-supported multithreading. This framework provides a formal grounding for the WCRT problem, and allows to improve upon earlier heuristics by accurately and modularly characterizing timing interfaces.
