The systematic design of large real-time systems or interface simplicity

Abstract

A key design decision during the development of large real-time systems concerns the decomposition of the system into a set of autonomous subsystem with simple and testable interfaces. In this paper it is argued that time-triggered architectures that eliminate the need for control signals passing subsystem interfaces are better suited for the implementation of large real-time systems than event-triggered architectures, where the control cannot be encapsulated.
