Worst-case execution time (WCET) prediction for modern
CPUA¢â‚¬â„¢s cannot make local assumptions about the impact
of input information on the global worst-case because
of the existence of timing anomalies. Therefore, static analyses
on the hardware level must consider a large subset of
the reachable states of the underlying hardware model. As
the number of states grows, WCET prediction can become
infeasible because of the increase in computation time and
memory consumption. This paper presents a solution for
this problem by defining the static analysis of processor
pipelines for WCET computation in terms of operations on
binary decision diagrams (BDDA¢â‚¬â„¢s).
