Power-aware hardware/software codesign of mobile devices

摘要

Power-aware hardware/software codesign defines a design methodology for the development of energy efficient embedded systems. With the appearance of energy-harvesting devices or RF-powered smart cards in recent years, the focus of the design process has been shifting from purely energy-oriented to power-constraints-oriented optimization strategies. In this paper we present an overview of various codesign flows and we motivate the importance of power awareness in today's design processes. Moreover, the industrial relevance of hardware/software codesign is shown in a case study of an RF-powered smart card system.
