[{"abstract":[{"lang":"eng","text":" In this thesis, we propose to use a reconfigurable processor as main computation element in embedded systems for applications from the multi-media and communications domain. A reconfigurable processor integrates an embedded CPU core with a Reconfigurable Processing Unit (RPU). Many of our target applications require real-time signal-processing of data streams and expose a high computational demand. The key challenge in designing embedded systems for these applications is to find an implementation that satisfies the performance goals and is adaptable to new applications, while the system cost is minimized. Implementations that solely use an embedded CPU are likely to miss the performance goals. Application-Specific Integrated Circuit (ASIC)-based coprocessors can be used for some high-volume products with fixed functions, but fall short for systems with varying applications. We argue that a reconfigurable processor with a coarse-grained, dynamically reconfigurable array of modest size provides an attractive implementation platform for our application domain. The computational intensive application kernels are executed on the RPU, while the remaining parts of the application are executed on the CPU. Reconfigurable hardware allows for implementing application specific coprocessors with a high performance, while the function of the coprocessor can still be adapted due to the programmability. So far, reconfigurable technology is used in embedded systems primarily with static configurations, e.g., for implementing glue-logic, replacing ASICs, and for implementing fixed-function coprocessors. Changing the configuration at runtime enables a number of interesting application modes, e.g., on-demand loading of coprocessors and time-multiplexed execution of coprocessors, which is commonly denoted as hardware virtualization. While the use of static configurations is well understood and supported by design-tools, the role of dynamic reconfiguration is not well investigated yet. Current application specification methods and design-tools do not provide an end-to-end tool-flow that considers dynamic reconfiguration. A key idea of our approach is to reduce system cost by keeping the size of the reconfigurable array small and to use hardware virtualization techniques to compensate for the limited hardware resources. The main contribution of this thesis is the codesign of a reconfigurable processor architecture named ZIPPY, the corresponding hardware and software implementation tools, and an application specification model which explicitly considers hardware virtualization. The ZIPPY architecture is widely parametrized and allows for specifying a whole family of processor architectures. The implementation tools are also parametrized and can target any architectural variant. We evaluate the performance of the architecture with a system-level, cycle-accurate cosimulation framework. This framework enables us to perform design-space exploration for a variety of reconfigurable processor architectures. With two case studies, we demonstrate, that hardware virtualization on the Zippy architecture is feasible and enables us to trade-off performance for area in embedded systems. Finally, we present a novel method for optimal temporal partitioning of sequential circuits, which is an important form of hardware virtualization. The method based on Slowdown and Retiming allows us to decompose any sequential circuit into a number of smaller, communicating subcircuits that can be executed on a dynamically reconfigurable architecture.

For this purpose we design and analyze solutions for size approximation, leader election and broadcasting. Our algorithms are fine-tuned for fast operation in a practical setting.

Both methods have been compared in terms of accuracy and computational effort. It is shown that they give comparable results if all numerical parameters are controlled carefully. LBM requires a much higher computational effort, however, in contrast to ASD it is able to simulate partially sintered agglomerates as well. The results show that even a very small amount of sintering leads to a significant reduction in the drag force. The analysis of the drag force on agglomerates as well as on aggregates shows that there is no simple geometric quantity which is uniquely related to the drag force. Moreover, there is a significant variation in drag force for single aggregates at different orientations or for the orientation averaged drag force of different aggregates of the same size. This is explained by the structural effects which may lead to a variation in the drag force up to +-20%."}],"type":"journal_article","publication":"Journal of Colloid and Interface Science"},{"issue":"6","publication_identifier":{"issn":["0009-286X","1522-2640"]},"publication_status":"published","intvolume":"        78","page":"694-699","citation":{"apa":"Horn, M., &#38; Schmid, H.-J.

Growth due to surface reaction and due to condensation is related to the fraction of the surface area that is exposed to the collision with single molecules. Surface shielding is found to hamper surface reaction and condensation once fractal aggregates start to form. It leads to significantly retarded precursor consumption and produces aggregate particles, which consist of more, but smaller primary particles. Surface energy data are varied within a range as proposed by available literature data. Moderate and high surface energy values result in a thermodynamic barrier to the formation of new particles and are shown to reduce the formation of seed particles by several orders of magnitude. This leads to the formation of aggregate particles which consist of a rather small number of primary particles and mainly grow by surface reaction. The primary contribution of condensation to growth of individual primary particles is shown to be very little. However, condensation should not be neglected as it has a strong impact on particle formation rates and hence on product characteristics such as the number of primary particles and primary particle size."}],"user_id":"70093","_id":"26150","language":[{"iso":"eng"}]},{"type":"book","status":"public","_id":"26721","department":[{"_id":"460"}],"user_id":"57672","extern":"1","language":[{"iso":"ger"}],"year":"2006","place":"Weinheim und Basel","citation":{"apa":"Hellmich, F., &#38; Kiper, H.
