WCET and industrial control code at SIES’11

York, UK, 24th March 2011 A paper which breaks new ground in the analysis of critical real-time applications is to be presented at SIES’11. Co-authored by Guillem Bernat and Michael Houston of Rapita Systems, “Large Drilling Machine Control Code - Parallelisation and WCET Speedup” details the results of the parallelisation and worst-case analysis of the control code of a large industrial drilling machine. Parallel execution on a multi-core processor is increasingly seen as an effective way to cope with the performance requirements of current and future hard real-time embedded systems. The study compared sequential, dual and quad parallel versions on the hard real-time capable MERASA multi-core processor. The timing behaviour was then analysed with RapiTime. The findings show how multi-core processors can support a parallelised, industrial real-time application and enable effective analysis of worst-case execution time on a multi-core processor. The 6th IEEE International Symposium on Industrial Embedded Systems (SIES’11) takes place in Vasteras, Sweden, from June 15th – 17th 2011. For more details visit www.mrtc.mdh.se/sies2011.
