TAXI: Trace Analysis for x86 Interpretation

Although x86 processors have been around for a long time and are the most ubiquitous processors in the world, the amount of academic research regarding details of their performance has been minimal. We introduce an x86 simulation environment, called TAXI (Trace Analysis for X86 Interpretation), and use it to present results for eight Win32 applications. In this paper, we explain the design and implementation of TAXI.
