Abstract

This paper proposes an original model of the execution time of assembly instructions in superscalar architectures. The approach is based on a rigorous mathematical model and provides a methodology and a toolset to perform data analysis and model tuning. The methodology also provides a framework for building new trace simulators for generic architectures. The results obtained show a good accuracy paired with a satisfactory computational efficiency.
