Composable Component Interfaces for Time-Triggered Systems

Abstract

When building real-time systems out of networked components, the use of temporal-firewall interfaces between the components supports a composable system design. This paper shows that, depending on the requirements of an application, the temporal-firewall interfaces of a time-triggered communication system can be accessed in two ways, either as data-sharing interfaces with asynchronous access or as time-aware interfaces with time-synchronized access. The paper describes each of these two ways of interfacing with a time-triggered communication system and characterizes their differences.
