NEXT TTA - High Confidence Architecture for Distributed Control Applications

EU Kutatási Keretprogram project
2002 - 2003

Local supervisor: Péceli Gábor
Official project supervisor: Bécsi Műszaki Egyetem, Ausztria

Objectives
The objective of the NEXT TTA project is to further improve the dependability and functionality of the time-triggered architecture (TTA). In particular the NEXT TTA project aims to:

  • Enhance the dependability of the TTA by developing a new physical interconnection structure with intelligent star couplers;
  • Integrate event-triggered and time-triggered communication within a single communication network while maintaining composability;
  • Integrate the synchronous programming environment LUSTRE into the TTA;
  • Develop highly automated WCET (worst case execution time) estimation algorithms;
  • Explore the limits of a COTS implementation of the TTA in the gigabit range.
Expected results
The NEXT TTA project will produce:
  • A prototype star coupler containing algorithms to tolerate arbitrary node failures and to detect degradation of node parameters before causing a fault;
  • Formal analysis of critical star coupler algorithms;
  • A methodology for integration of event-triggered and time-triggered communication, demonstrated by a prototype and supported by software tools;
  • A prototype implementation of the integration of LUSTRE into the TTA and tools for WCET analysis.
