Abstract

Caches are a mandatory feature of current processors to deliver instructions and data to a fast processor pipeline. However, standard cache organizations are designed to increase the average case performance. They are hard to model for worst-case execution time (WCET) analysis. Unknown abstract cache states during the analysis result in conservative WCET bounds. Therefore, we propose to adapt the cache organization to simplify the analysis. The data cache is split into several independent caches for the stack, static data, constants, and heap allocated data.
