Zusammenfassung
Power-aware Hardware/Software Codesign definiert eine Design-Methode für die Entwicklung energieeffizienter, eingebetteter Systeme. Durch das verstärkte Aufkommen von Geräten, die ihre Energie aus der Umgebung beziehen ("Energy Harvesting") oder kontaktlos über ein RF-Feld versorgt werden, hat sich auch der Fokus des Designprozesses verlagert. Statt sich ausschließlich auf die Energieoptimierung zu konzentrieren, müssen nun auch immer stärker Einschränkungen bezüglich der Leistungsaufnahme berücksichtigt werden. In diesem Artikel werden verschiedene Codesign-Flows vorgestellt und deren Bedeutung in der Entwicklung von leistungs- und energieeffizienten Systemen unterstrichen. Darüber hinaus wird die industrielle Relevanz des Hardware/Software Codesigns anhand eines konkreten Anwendungsfalls in der Anwendungsdomäne von kontaktlosen Chipkarten gezeigt.
Summary
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.
