"Integration of two Complementary Time-Triggered Technologies: TMO and TTP";
Vortrag: International Embedded Systems Symposium, Manaus, Brazil; 15.08.2005 - 17.08.2005; in: "Proceedings of the International Embedded Systems Symposium 2005", Springer, (2005), ISBN: 0-387-27557-6; S. 1 - 12.

The TMO model for real-time distributed object-computing supports the specification of temporal
constraints with respect to a global time base and provides execution engines for ensuring that these
constraints are met at runtime. This paper describes a solution for supporting TMO applications on top
of the Time-Triggered Architecture, a system architecture that meets the dependability requirements
of safety-critical applications. Thereby, the TMO model advances to the domain of safety-related and
safety-critical systems. Due to an ongoing trend in transportation systems (e.g., automotive industry)
of increasing functionality and complexity, this domain can benefit from the intuitive and programmer-
friendly TMO scheme. We realize TMO on top of the TTA by establishing a Kernel Abstraction
Layer (KAL) for the TTP/RTAI-Linux platform. This KAL maps the platform services used by the
TMO support middleware to the service of the TTP protocol and the operations of RTAI-Linux. KAL
also layers event-triggered communication for remote method invocations and multicast channels on
top of the purely time-triggered TTP protocol.
