Abstract:
Advancements in today's mobile computing systems are mainly constrained by the high power dissipation of integrated circuits. Enhancing the energy efficiency of these systems has become a pressing challenge due to their dependency on batteries as the main power source. In this paper, we present a component-wise energy consumption breakdown of a modern platform under a variety of applications and benchmarks. This is an essential step in directing future research towards the power-hungry components and in providing a better understanding of the system behavior. Our results demonstrate a substantial variation in the energy contribution of various components as well as the total system energy depending on the nature of the workload. © 2011 IEEE.
