In Proceedings of the 2012 ACM/IEEE International Symposium on Low Power Electronics and Design, 267-272, Redondo Beach, California. doi:10.1145/2333660.2333722978-1-4503-1249-3http://nrs.harvard.edu/urn-3:HUL.InstRepos:34728751Simulation is one of the main vehicles of computer architecture research. In this paper, we present XIOSim - a highly detailed microarchitectural simulator targeted at mobile x86 microprocessors. The simulator execution model that we propose is a blend between traditional user-level simulation and full-system simulation. Our current implementation features detailed power and performance core models which allow microarchitectural exploration. Using a novel validation methodology, we show that XIOSim's performance models manage to stay well within 10% of real hardware for the whole SPEC CPU2006 suite. Furthermore, we validate power models against measured data to show a deviation of less than 5% in terms of average power consumption.en-USin-orderpower-performancesimulationx86Conference Paper10.1145/2333660.2333722
