The Mälardalen WCET Benchmarks - Past, Present and Future

Proceedings of the 10th International Workshop on Worst-Case Execution Time Analysis
Abstract
Modelling of real-time systems requires accurate and tight estimates of the Worst-Case Execution
Time (WCET) of each task scheduled to run. In the past two decades, two main paradigms have
emerged within the field of WCET analysis: static analysis and hybrid measurement-based analysis.
These techniques have been successfully implemented in prototype and commercial toolsets. Yet, comparison
among the WCET estimates derived by such tools remains somewhat elusive as it requires a
common set of benchmarks which serve a multitude of needs.
The Mälardalen WCET research group maintains a large number of WCET benchmark programs for
this purpose. This paper describes properties of the existing benchmarks, including their relative
strengths and weaknesses. We propose extensions to the benchmarks which will allow any type of
WCET tool evaluate its results against other state-of-the-art tools, thus setting a high standard for
future research and development.
We also propose an organization supporting the future work with the benchmarks. We suggest to form
a committee with a responsibility for the benchmarks, and that the benchmark web site is transformed
to an open wiki, with possibility for the WCET community to easily update the benchmarks.
