Component-based applications require runtime support to be able to guarantee non-functional properties. This paper proposes an architecture for a real-time-capable, component-based runtime environment, which allows to separate non-functional and functional concerns in component-based software development. The architecture is presented with particular focus(More)
We present enforceable component-based realtime contracts, the first extension of component-based software engineering technology that comprehensively supports adaptive realtime systems from specification all the way to the running system. To provide this support, we have extended component-based interface definition languages (IDLs) and component(More)
Disregarding non-functional properties is an important project risk. They have to be taken into consideration throughout the system's life cycle. Particularly, they must be considered as early as possible in the design phase. Especially in the area of component-based software development it is also important to be able to separate functional and(More)
Zusammenfassung Die DFG-Forschergruppe 428 COMQUAD an der TU Dresden hat zum 1. Oktober 2001 die Arbeit aufgenommen. Sie befasst sich mit nichtfunk-tionalen Eigenschaften von komponentenbasierten Software-Systemen, insbe-sondere mit zusagbaren quantitativen Eigenschaften, Adaptionsfähigkeit und Sicherheit. Dieser Beitrag beschreibt die Ziele der(More)

RF-MEMS filters such as Bulk-Acoustic-Wave (BAW) filters are determined to replace conventional RF-filters in mobile communication as they have demonstrated performance and size advantages and can be manufactured at very low costs. Key performance parameters and requirements are discussed in detail. Two different approaches for RF-MEMS filters are reviewed(More)
We propose to create tailor-made application servers by composing components providing support for individual non-functional properties. In this position paper we start from a static, asymmetric approach splitting the application server in two parts to support realtime properties and generalize this to a symmetric, componentized architecture. We then(More)
Commodity CPU architectures, such as ARM and Intel CPUs, have started to offer trusted computing features in their CPUs aimed at displacing dedicated trusted hardware. Unfortunately, these CPU archi-tectures raise serious challenges to building trusted systems because they omit providing secure resources outside the CPU perimeter. This paper shows how to(More)
