International audienceThe scheduling of reliable real-time systems require a precise and sound analysis of the execution times of their tasks. Part of these execution times is spent fetching data from the main memory to the cache memories. These fetch events occur on cache misses, but cache misses are hard to predict when the program accesses an array. An imprecise cache miss analysis can lead to an imprecise but still sound Worst-Case Execution Time (WCET) analysis. In this article we present a framework for deriving an upper bound to the number of times a data-accessing instruction triggers a cache miss. Backed by this framework, we present an analysis that produces numeric or symbolic bounds, by reasoning on a short history of accesses a...
