In the preprocessing, images for discrete viewpoints and viewing directions are rendered and stored on an external volume. During navigation each image can be displayed within a very short time by loading it from the volume. For acceleration, our prefetching strategy loads possibly needed images for the next few frames if the viewer takes a break. The measurements show that we achieve interactive frame rates, whereby the difference between the minimal and maximal display time is very small. Our system works well with scenes modelled by polygons, but also digital photos can easily be used for describing a 3D scene.

Kolloquiumsvortrag im Fach Germanistik der Universität Essen ER - TY - CONF AB - Wearable computers are embedded into the mobile environment of the human body. A design challenge for wearable systems is to combine the high performance required for tasks such as video decoding with low energy consumption required to maximize battery runtimes and the flexibility demanded by the dynamics of the environment and the applications. In this paper, we demonstrate that reconfigurable hardware technology is able to answer this challenge. We present the concept and the prototype implementation of an autonomous wearable unit with reconfigurable modules (WURM). We discuss two experiments that show the uses of reconfigurable hardware in WURM: ASICs-on-demand and adaptive interfaces. Finally, we develop and evaluate task placement techniques used in the operating system layer of WURM.

Symp. on Wearable Computers (ISWC) TI - Reconfigurable Hardware in Wearable Computing Nodes ER - TY - CONF AB - Recent generations of high-density and high-speed FPGAs provide a sufficient capacity for implementing complete configurable systems on a chip (CSoCs). Hybrid CPUs that combine standard CPU cores with reconfigurable coprocessors are an important subclass of CSoCs. With partially reconfigurable FPGAs, coprocessors can be loaded on demand while the CPU remains running. However, the lack of high-level design tools for partial reconfiguration makes practical implementations a challenging task. In this paper, we introduce a design flow to implement hybrid processors on Xilinx Virtex. The design flow is based on two techniques, virtual sockets and feed-through components, and can efficiently generate partial configurations from industry-quality cores. We discuss the design flow and present a fully operational audio streaming prototype to demonstrate its feasibility.

Four accelerator architectures are developed that implement branch \& bound in 3-valued logic and many of the deduction techniques found in software solvers. We use set covering benchmarks from two-level logic minimization and Steiner triple systems to derive and discuss experimental results. The resulting raw speedups are in the order of four magnitudes on average. Finally, we propose a hybrid solver architecture that combines the raw speed of instance-specific reconfigurable hardware with flexible bounding schemes implemented in software.
