Abstract

With the emergence of both power and performance as primary design constraints, energy efficiency has become the new design criteria. A platform with heterogeneous-ISA processors can provide multiple power-performance execution points needed for a varied mix of workloads. We argue that a new system software architecture is needed to obtain maximum energy efficiency on such heterogeneous-ISA platforms. We present our system software, a replicated-kernel operating system and a compiler framework, and quantify the advantages of such a system software on ARM-x86 using simulations. Based on our experimental observations, we propose a scheduling approach which considers system and application runtime characteristics along with platform profiles to maximize energy efficiency.
