ABSTRACT
Abstract: Microprocessor design time and effort are getting impractical due to the huge number of simulations that need to be done to evaluate various processor configurations for various workloads. An early design stage methodology could be useful to efficiently cull huge design spaces to identify regions of interest to be further explored using more accurate simulations. In this paper, we present an early design stage method that bridges the gap between analytical and statistical modeling. The hybrid analytical-statistical method presented here is based on the observation that register traffic characteristics exhibit power law properties which allows us to fully characterize a workload with just a few parameters which is much more efficient than the collection of distributions that need to be specified in classical statistical modeling. We evaluate the applicability and the usefulness of this hybrid analytical-statistical modeling technique to efficiently and accurately cull huge architectural design spaces. In addition, we demonstrate that this hybrid analytical-statistical modeling technique can be used to explore the entire workload space by varying just a few workload parameters.
