Supporting Heterogeneous Applications in the DECOS Integrated Architecture

The DECOS integrated time-triggered architecture provides a framework for integrating multiple heterogeneous real-time application subsystems within a single distributed computer system while retaining the fault-isolation, fault-containment and complexity-management benefits of a classic federated system. A central issue in the DECOS architecture is the provision of standardized, validated and certified services that facilitate the development of distributed real-time applications. This paper describes how these services are structured within the architecture in order to satisfy the diverse requirements of heterogeneous applications (e.g. different real-time requirements, different criticality levels). In particular we focus on the reuse of legacy subsystems, and show the feasibility of our concept by implementing a Controller Area Network (CAN) application within the integrated architecture. 1
