Europe invests in safety critical development

The Open Group and the Technical University of Denmark ( DTU) are forming a consortium of European real-time technology developers, industrial suppliers and research organizations to develop a platform architecture for safety-critical real-time systems for avionics, transportation and other safety-related domains.

Supported by the European Commission, the Time-Predictable Multicore Architecture for Embedded Systems (T-CREST) project is investing more than €3.6 million (US$4.6 million) to develop an advanced multicore architecture that will enable substantial performance increases for safety-critical systems.

This supplier-independent framework will incorporate newly designed components that provide added predictability and reliability essential for safety-critical applications, while providing improvements in developer productivity, system verification costs, and lower costs for maintenance.

Coordinated by The Open Group with technical leadership from DTU, the T-CREST consortium includes: University of York, Vienna University of Technology and Eindhoven University of Technology, each of which are centres for research in system platform design; AbsInt, a provider of specialized tools for analyzing safety-critical systems; and industrial solution suppliers Intecs and GMV, both leading European providers of safety-critical transportation systems.

DTU is directing the advanced research in new architecture designs and analysis tools that will enable multicore processors to be used for applications where strict predictability, reliability and real-time performance are required by industry.

“The T-CREST project brings together experts addressing each element of system platform design and analysis to develop new approaches for implementing components that support timing analysis and ensure predictability of the overall system,” said David Lounsbury, Chief Technical Officer, The Open Group. “We’re confident these new technologies will make their way into next-generation platform designs to provide needed performance boosts for safety-critical systems, while allowing software developers to verify that systems perform within the precise time intervals demanded by critical systems in avionics, automotive, railway and other safety-related domains.”

The main objective of the T-CREST project is to research and develop novel solutions for time-predictable multicore and many-core system architectures using time-predictable resources for processors, interconnects, memories, and other components. These new solutions will be designed to accommodate analysis of worst-case execution time (WCET) so exact timings of a safety-critical system can be verified, and WCET performance is optimised on multicore systems.
