Abstract
DECOS (Dependable Components and Systems) is an EU-funded integrated research project (IP) with the goal to develop a framework and an associated design methodology for the component-based design of dependable embedded systems. The core of DECOS is based on the Time-Triggered Architecture (TTA), a distributed architecture for high-dependability real-time applications. In the first part of this paper the design flow of DECOS from the Platform Independent Model (PIM) to the Platform Specific Model (PSM) is discussed and the DECOS execution environment is introduced. In the second part the fault-tolerance mechanisms of DECOS are explained. After a deliberation of the fault hypothesis, the support for the implementation of triple-modular redundancy (TMR) is presented.
