— Communication networks today are facing an ever increasing network traffic as well as raising quality-of-service agreements, which together demand for high performance network routers. Since a router has to search a large set or routing rules for every incoming packet, it normally utilizes efficient search mechanisms, such as trees or hash tables. This(More)
With a fast rising productivity and even faster rising integration densities, i.e., design-productivity-gap, energy and power dissipation are critical topics in high level system design more than ever. Thermal aware system design, reliable power delivery, and the overall energy dissipation are only few crucial design properties. In this work we present a(More)
Because of the aggressive scaling of integrated circuits and the given limits of atomic scales, circuit designers have to become more and more aware of the arising reliability and yield concerns. So far, only very little research efforts have been put into low-level approaches for lifetime reliability, whereas lots of efforts have focused on soft-errors and(More)
—As transistor dimensions are shrinking into regions of only a few atomic layers, designers are faced with various problems including increased reliability and power issues. Since these problems are amplified by higher circuit temperatures, this paper proposes an approach for the fine-grained modeling of temperature distribution in many-core systems based(More)
— Because of the aggressive scaling into the nanometer regime, degradation due to wearout significantly impairs design parameters. For instance, such wearout is caused by gate oxide breakdown, which decreases the operating lifetime of integrated circuits to an extent that cannot be neglected by circuit designers to date. In this paper, we introduce an(More)
—Progressive technology scaling raises the need for efficient VLSI design methods facing the increasing vulnerability to permanent physical defects, while considering power efficiency of resulting circuit implementations at the same time. Triple Modular Redundancy (TMR) represents a common method to encounter reliability problems, but has the drawback of(More)
Increasing integration densities and the emergence of nanotechnology cause issues related to reliability and power consumption to become dominant factors for the design of modern multi-core systems. Since the arising problems are enforced by high circuit temperatures, monitoring and control of on-chip temperature profiles need to be considered during design(More)
— In modern networks, the requirements towards network equipment rise together with the bandwidth. Customers and internet service providers ask for more and more services like Voice-over-IP, IP-TV, and data services with a dependable quality. To satisfy these demands, the requirements towards packet classification as key functionality in network equipment,(More)
