When designing heterogeneous MP-SoCs designers have to take into account various objectives such as power, die size, flexibility, performance or programmability. But to be able to evaluate a given system according to these objectives, it is necessary to know how applications will behave on that system. Since time-to-market is one key factor in chip design,(More)
In embedded computing we face a continuously growing algorithm complexity combined with a constantly rising number of applications running on a single system. Multi-core systems are becoming popular to cope with these requirements. Growing computational complexity is handled by increasing the number of cores and core types within one system - leading to(More)
The computational demand of signal processing algorithms is rising continuously. Heterogeneous embedded multiprocessor systems-on-chips are one solution to satisfy this demand. But to be able to take advantage of these systems, new strategies are required to map applications to such a system and to evaluate the systems performance at a very early design(More)
Modern multi-core processors suffer from the lack of a programming model which allows efficient utilization of the available hardware. Massive software overhead is required to handle task scheduling and synchronization, resulting in power inefficiencies. In this paper we present a C++ based, real-time enabled task level programming model, which allows(More)
Applications for system on chips become more and more complex. Also the number of available components (DSPs, ASICs, Memories, etc.) rises continuously. These facts necessitate a structured method for selecting components, mapping applications and evaluating the chosen configuration and mapping. In this work we present a methodology for the last named. We(More)
The computational demand of signal processing algorithms is rising continuously. Heterogeneous embedded multiprocessor systems-on-chips are one solution to tackle this demand. But to be able to take advantage of the benefits of these systems, new strategies are required how to map applications to such a system and how to evaluate the system’s performance at(More)
In the past signal processing algorithms for mobile communications systems were implemented in hardware using a single chip solution, usually a Digital Signal Processor (DSP). But due to the increased and still increasing complexity of these signal processing algorithms, the computational power of single chip solutions is not sufficient any more. In(More)
1. Sowohl DXM wie PRED in niedriger Dosierung supprimieren bereits nach vierwöchiger Therapie pathologisch erhöhte Androgenwerte. 2. DXM ist deutlich wirksamer als PRED 3. Die F-Sekretion wird durch die Gabe von GCC nicht total gehemmt. 4. DXM supprimiert nicht nur die adrenale sondern auch die ovarielle Androgensekretion. 5. Die Nebenwirkungen einer(More)
