Abstract
This paper compares the temporal properties of event-triggered and timetriggered distributed real-time systems. In an event triggered system a processing activity is initiated as a consequence of the occurrence of a significant event. In a time-triggered system, the activities are initiated periodically at predetermined points in real-time. In the first part of this paper, a model of a distributed real-time system is presented and the characteristic attributes of TT-systems and ET-systems are described. The comparison focuses on the issues of predictability, testability, resource utilization, extensibility, and assumption coverage.
