Modeling out-of-order processors for WCET analysis
Estimating the Worst Case Execution Time (WCET) of a program on a given processor is important for the schedulability analysis of real-time systems. WCET analysis techniques typic...

Timing Anomalies in Dynamically Scheduled Microprocessors
Previous timing analysis methods have assumed that the worst-case instruction execution time necessarily corresponds to the worst-case behavior. We show that this assumption is wr...

Optimal static WCET-aware scratchpad allocation of program code
Caches are notorious for their unpredictability. It is difficult or even impossible to predict if a memory access will result in a definite cache hit or miss. This unpredictabilit...

Temperature-Aware Scheduling and Assignment for Hard Real-Time Applications on MPSoCs
—Increasing integrated circuit (IC) power densities and temperatures may hamper multiprocessor system-on-chip (MPSoC) use in hard real-time systems. This article formalizes the t...

Usability Aspects of WCET Analysis
Knowing the program timing characteristics is fundamental to the successful design and execution of real-time systems. A critical timing measure is the worst-case execution time (...
