Abstract

In this p ap er we pr esent our novelpower exploration methodolo gy for applic ations with dynamic data types. Our methodolo gy is crucial to obtain effe ctive solutions in an emb edded (HW or SW) processor context. The c ontributionsare twofold. First we define the complete search sp ace for Virtual Memory Management (VMM) mechanisms in a structured way with orthogonal de cision tr eesSe condly we present our systematic methodolo gy for explor ation of the maximal power that takes into account characteristics of the application to he avily prune the search space guiding the choies of a VMM mechanism. Finally we demonstrate for two industrial examples that power can vary consider ably dep ending on the VMM chosen. Moreover these exp eriments show the effe ctiveness of our exploration methodolo gy.
