A datapath synthesis system (DPSS) for the reconfigurable datapath architecture (rDPA) is presented. The DPSS allows automatic mapping of high level descriptions onto the rDPA without manual interaction. The required algorithms of this synthesis system are described in detail. Optimization techniques like loop folding or loop unrolling are sketched. The(More)
Communication mechanisms within concurrent computer systems are extremely hostile to optimizing compilers. Also vector machines have fundamental performance bottlenecks [33][35] and their sustained average performance is by several orders of magnitude lower, than their peak rate [15, 33], even when creative coding techniques help the compiler [34].

We analyzed characteristics, therapy and outcome of patients with bilateral testicular germ cell tumor (TGCT) at our institutions. Among 1,180 TGCT patients diagnosed and/or treated between 1979 and 2003, 47 (4.0%) developed a second TGCT. Nine of 14 patients (64%) with synchronous TGCT are alive with no evidence of disease (NED) at a median follow-up of 37(More)
The paper is a plaidoyer for a radical methodological change in R&D of dynamically reconfigurable circuits. The paper illustrates, that the current main stream approach based on placement and routing is not very likely to obtain the area-efficiency and throughput needed to cope with the emerging crisis cost of future silicon technology generations. The(More)
Coarse-grain reconfigurable architectures have been a matter of intense research in the last few years. They promise to be more adequate for computational tasks due to their better efficiency and bigger speed. As the coarse granularity implies also a reduction of flexibility, a universal architecture seems to be hardly feasible. Based on the KressArray(More)
C onfigurable computing systems combine programmable hardware with programmable processors to capitalize on the strengths of hardware and software. Often these systems must also address the difficulties of both hardware and software, because they mix the technology. While the origins of configurable computing go back at least 30 years, the past eight years(More)
This chapter introduces morphware as the basis of a second machine paradigm, which mainly has been introduced by the discipline of embedded system design targeting the System on Chip (SoC). But more recently SoC design is adopting more and more computer science mentality and also needs the services of CS professionals. Computing Sciences are going to(More)
