Everything you (n)ever wanted to know about caches
Dr. Jan Reineke (Saarland University, Germany)

with an introduction by:
Prof. Dr. Dr. h.c. mult. Reinhard Wilhelm (Saarland University, Germany)

Embedded systems as they occur in application domains such as automotive, aeronautics, and industrial automation often have to satisfy hard real-time constraints. Safe and precise bounds on the worst-case execution time (WCET) of each task have to be derived.
In this talk I will discuss the influence of the cache architecture on the
precision and soundness of WCET analyses, by
- evaluating predictability metrics that capture the inherent uncertainty in any cache analysis.
- introducing the notion of relative competitiveness, which allows to derive new cache analyses that are optimal w.r.t. the predictability metrics
- investigating the soundness of measurement-based WCET analysis in the presence of caches.
