Effective Uilitzation of Modern Mobile CPU's Asymmetric Characteristics

Abstract

In this research, we demonstrate the fundamental inefficiency of the asymmetric multicore architecture in modern mobile CPUs, and propose two principles for the effective utilization of the asymmetric characteristics of modern mobile CPUs; power-efficient cluster with sufficient performance and high-speed cluster with reasonable performance. In the experimental study, the proposed principles reduced the energy consumption up to 37% while not harming system performance. The experimental results demonstrate that the proposed principles can be used to improve the power efficiency while not harming QoS.
