The Time-Triggered Approach to Real-Time System Design
In this paper the basic assumptions that govern the design of timetriggered(TT) real-time systems are examined and the characteristic properties of these architectures are analyzed. The paper introduces a real-time system model and discusses the important concept of temporal accuracy of real-time data. The fundamental paradigm behind the time-triggered design approach is explained in detail. The services and the basic design principles of the time-triggered communication protocol TTP are presented. Finally, the services of a TT architecture are assessed from the points of view of predictability, testability. resource utilization, and assumption coverage.
