Consideration on a power-saving and reliable embedded system
Gaku Nakagawa, Shuichi Oikawa · 2012
Workloads for embedded systems, such as smart phones and tablet computers, are increasing its complexity. Thus, they often have high performance processor. This is barrier to achieve green computing. Heterogeneous multi-core architectures are an solution for this problem because they can reduce wasting power when they are idle. In this study, we propose the efficient architecture of an operating system, so that the potential of heterogeneous multi-core architectures can be exploited. As a proof of concept, we implement a simulator of operating system. This paper describes the proposed architecture and the implementation of the simulator.
