The supply voltage level has emerged as an important metric alongside power consumption information to investigate system stability and reliability issues. In this paper, we propose a supply voltage emulation platform based on a power emulation approach to derive real-time power and supply voltage information from a system. Moreover, we present a dynamic voltage and frequency scaling (DVFS) based voltage drop compensation scheme to maintain stable system operation. The early design phase applicability of our emulation-based approach enables the investigation of the effectiveness of voltage drop compensation schemes before the final chip is available.

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. Keywords: power awareness; hardware/software codesign; smart cards; power emulation Power-aware Hardware/Software Codesign fü r mobile Systeme.Power-aware Hardware/Software Codesign definiert eine Design-Methode fü r die Entwicklung energieeffizienter, eingebetteter Systeme. Durch das verstä rkte Aufkommen von Gerä ten, die ihre Energie aus der Umgebung beziehen ("Energy Harvesting") oder kontaktlos ü ber ein RF-Feld versorgt werden, hat sich auch der Fokus des Designprozesses verlagert. Statt sich ausschließlich auf die Energieoptimierung zu konzentrieren, mü ssen nun auch immer stä rker Einschrä nkungen bezü glich der Leistungsaufnahme berü cksichtigt werden.In diesem Artikel werden verschiedene Codesign-Flows vorgestellt und deren Bedeutung in der Entwicklung von leistungs-und energieeffizienten Systemen unterstrichen. Darü ber hinaus wird die industrielle Relevanz des Hardware/Software Codesigns anhand eines konkreten Anwendungsfalls in der Anwendungsdomä ne von kontaktlosen Chipkarten gezeigt.
