NEXT TTA

High-Confidence Architecture for Distributed Control Applications

IST Programme RTD Research Project IST-2001-32111.
1 January 2002 to 31 December 2003

The NEXT TTA project enhances the structure, functionality and dependability of the time-triggered architecture (TTA) to meet the austere cost structure of the automotive industry, while satisfying the rigourous safety requirements of the aerospace industry. By placing the safety-relevant algorithms, that are formally analyzed, into intelligent replicated star couplers, NEXT TTA reduces the cost and generalizes the failure assumptions of the node computers. Event-triggered communication services are integrated into the TTA to increase the required flexibility. The synchronous programming environment LUSTRE and its tool set are extended for the TTA and automated worst-case-execution-time analysis is explored. CORBA compliant interfaces are provided in order to make TTA systems interoperable with the open information infrastructure. The limits of implementing the TTA with COTS components in the gigabit range are investigated.
