The efficient realization of self-organizing systems based on 2D stencil code applications, like our developed Marching Pixel algorithms, is a great challenge. They are data-intensive and also computational-intensive, because often a high number of iterations is required. FPGAs are predestined for the realization of these algorithms. They are very flexible,(More)
Path Planning is one of the most computationally intensive tasks in robot systems and a challenge in dynamically changing environments. By means of FPGAs it is possible to process time-critical and data-intensive tasks in robot systems efficiently. We have developed a parallel path planning algorithm which is based on Marching Pixels, an organic computing(More)
The paper introduces a two stage multiuser detector for CDMA downlink systems. Frequency domain equalization (FDE) is used at the first stage as a single-user detector. A RAKE receiver is then employed at the second stage, following a parallel interference cancellation (PIC) process. The performance of the FDE-RAKE detector is evaluated in a UTRA-TDD(More)
The usage of Cellular Automata (CA) for image processing tasks in self-organizing systems is a well known method, but it is a challenge to process such CAs in an embedded hardware efficiently. CAs present a helpful base for the design of both robust and fast solutions for embedded image processing hardware. Therefore, we have developed a system on a chip(More)
Image processing in machine vision is a challenging task because often real-time requirements have to be met in these systems. To accelerate the processing tasks in machine vision and to reduce data transfer latencies, new architectures for embedded systems in intelligent cameras are required. Furthermore, innovative processing approaches are necessary to(More)
Due to the increasing needs of always faster automation technology in the field of industrial fabrication the common methods of machine vision meet their limits. The reasons are the widely used serial computation and transmission of data streams on the base of strict spatially separated data capturing by an image sensor and data processing, e.g. by a(More)
A pump-probe experimental approach has been shown to be a very efficient tool for the observation and analysis of various laser matter interaction effects. In those setups, synchronized laser pulses are used to create an event (pump) and to simultaneously observe it (probe). In general, the physical effects that can be investigated with such an apparatus(More)
We present a fine-grain parallel processor chip which can be embedded in very compact machine vision systems, e.g. in 3d stacked die assemblies. Smart and fast vision systems are frequently required in industrial environments to automatically detect and inspect objects, e.g. on an assembly line. The chip die has a size of 25 mm² and is manufactured(More)
