To support portability, worst-case execution time (WCET) analysis of Java byte code is performed at two levels - machine-independent program flow analysis at a higher level and machine-dependent timing analysis of individual program constructs at a lower level. This paper contributes a WCET analysis that computes worst-case execution frequencies of Java byte codes within the software being analysed and accounts for platform-dependent information, i.e. the processor's pipeline. The main part of the approach is platform-independent; only a limited analysis is needed on a per-platform basis.
