The time-triggered architecture is architecture for distributed embedded real-time systems in high dependability applications. The core element of the architecture is the time-triggered communication protocol TTP/C. This paper shows how a Fault-Tolerance Layer that performs those functions that are necessary for the implementation of redundancy can extend TTP/C. The hardware/software interface of the host computer, where the application software is executing, is changed, neither in the value domain, nor in the temporal domain, by this implementation of fault-tolerance in the communication system. Provided the application software has been properly organized, it is thus possible to implement redundancy transparently, i.e., without any modification of the function and timing of the application system. The paper also discusses the experiences gained from a prototype implementation of the fault-tolerance layer in the microprogram of a TTP/C controller chip.
