Due to their layered approach, Networks-on-Chip (NoC) are a promising communication backbone in the field of heterogeneous dynamically reconfigurable systems. In this paper a future FPGA architecture is discussed having a hardwired NoC as an additional high-level routing resource. Instead of implementing on-chip interconnection with valuable reconfigurable(More)
Die Kombination aus Standardprozessoren und rekonfigurierbarer Hardware hat sich in Forschung und kommerziellen Anwendungen mit schnell veränderlichen Parametern und Protokollen als flexible und leistungsfähige Architektur erwiesen. Jedoch werden die Möglichkeiten der dynamischen partiellen Rekonfigurierbarkeit noch nicht ausgenutzt, durch die eine weitere(More)
Partial dynamic reconfigurability of modern FPGAs holds the potential of realizing autonomous and highly flexible systems-on-chip (SoC). Current devices can be configured with several partial bitfiles and replace particular ones on demand. But these precompiled bitfiles seriously lack flexibility: they are hardly relocatable and not adjustable. In other(More)
1. The secondary structure of human interleuken-3 in solution was determined by circular dichroism spectroscopy. 2. The results were then compared with empirical secondary structure predictions based on primary sequence structure of the protein. 3. The two approaches are in extremently close agreement showing the protein to have 40% alpha-helix, 12% total(More)
Managing reconfigurable hardware resources at runtime is expected to be a new task for future operating systems. But due to the mixture of parallel and sequential parts of dynamically reconfigurable applications, it is not entirely clear so far, how to use and to program such systems. A new interpretation of dynamically reconfigurable applications is(More)
During the last years, networks-on-chip (NoCs) have become a true alternative for the design of complex integrated systems-on-chip (SoC). Much effort has been spent for research on functionalities, mechanisms, and quality-of-service (QoS) features in NoCs. Hence, a broad and multi-faceted design space exists but leaves open, which mechanisms and design(More)
Meeting the high demands of outer space missions requires immense efforts and is exceedingly time consuming. For the latest accomplished missions, the engineering of the hardware and computing systems took years and must be completed before launch. The architecture of a Network on Chip (NoC) based System on Chip (SoCs) is presented in this paper. These SoCs(More)
Dealing with uncertainty is an important issue in a broad range of research fields and industrial applications. For example with outer space missions or unmanned vehicles in perilous environs, today’s and future systems have to adapt to changing environmental conditions. But high specialization of today’s systems also results in decreased robustness and(More)
1. The site of proline dehydrogenase (EC 1.5.99.-) activity in blowfly (Phormia regina) flight muscle mitochondria has been investigated employing the inner membrane-impermeable Fe(CN)63-as electron acceptor. Antimycin had no inhibitory effect on ferricyanide reduction due to proline dehydrogenase activity. Ferricyanide reductase activity due to inside(More)
Zone electrophoresis separations of human recombinant interleukin-3 (rh IL-3) and related proteins in untreated fused silica capillaries are presented. Results using pH 9 CHES buffer show that rh IL-3 is easily separated from a common carrier, human serum albumin, in a commercial preparation.
