Abstract: ROSACE - for Research Open-Source Avionics and Control Engineering - goes from a baseline flight controller, developed in MATLAB/SIMULINK, to a multi-periodic controller executing on a multi/many-core target. The interactions between control and computer engineers are highlighted during the development steps, in particular by investigating several multi-periodic configurations. We deduced ways to improve the discussion between engineers in order to ease the integration on the target. The whole case study is made available to the community under an open-source license.

Benchmarks • Real world automotive benchmark for free

Title: Real World Automotive Benchmark For Free

Authors: Simon Kramer, Dirk Ziegenbein, Arne Hamann (Corporate Research, Robert Bosch GmbH, Renningen, Germany)

Abstract: The progress and comparability of real-time analysis methods that are applicable to real-world is slowed by the absence of realistic benchmarks, mainly due to intellectual property (IP) concerns. We propose a method that supports the generation of realistic but IP free benchmark sets. Further, we provide the application characteristics of a specific real-world automotive software system.

Benchmarks • GMCB: An industrial benchmark for use in real-time mixed-criticality networks-on-chip

Title: GMCB: An Industrial Benchmark for Use in Real-Time Mixed-Criticality Networks-on-Chip

Authors: James Harbin, Tom Fleming, Leandro Soares Indrusiak, Alan Burns (Real-Time Systems Group, Department of Computer Science, University of York, UK)

Abstract: This paper specifies and describes GMCB (Generic Mixed-Criticality Benchmark), a benchmark industrial application model for testing real-time mixed-criticality multicore systems incorporating a network-on-chip (NoC). Task execution information such as periods, latencies and criticality levels is specified. The communication patterns between the tasks are defined, incorporating message sizes transmitted between the source and destination nodes. Cycle-accurate NoC simulation is used to evaluate the performance of the GMCB model, evaluating the communication latencies encountered under various task mappings. The behaviour of the application under a recent mixed-criticality NoC protocol is considered.
