Issues using the Nexus Interface for Measurement-Based WCET Analysis

Abstract

Hardware debug interfaces such as Nexus have the power to unleash the full potential of measurement-based WCET approaches due to the passive nature in which timing data are collected from the processor. However, difficulties arise as a result of their restrictive nature, thus disallowing true user freedom in the selection of instrumenta- tion point placement. This paper elaborates on the problems encountered when using the Nexus inter- face in our measurement-based WCET framework, and how some of these issues can be resolved, par- ticularly that of irreducibility.
