The increasing urgency to study the world's native water bodies regarding environmental monitoring leads to a worldwide growing interest in the development of Autonomous Underwater Vehicles (AUVs). The robots are equipped with several sensors, e.g. cameras, environmental tracking systems and acoustic modules which provide an inexpensive alternative to(More)
This paper presents a low-power microcontroller-based acoustic modem for low-range communication based on aspects of whale and dolphin communication. The approach is to decrease influences by using a frequency shift keying (FSK) modulation combined with frequency hopping spread spectrum (FHSS). Addressing individual recipients (unicast) as well as a group(More)
Design space exploration and detailed analysis in the field of hardware design applies simulation in many variants. A frequently used method is stochastic simulation where systems are stimulated by randomised input. Synthetic traffic traces mainly form the load for stochastic simulation of network computing devices. The generator presented here utilises two(More)
This paper presents a concept for online detection and prioritization of semi-static data streams in network-on-chips. Semi-static data streams are characterized by a number of consecutive packets following the same path for a longer period of time. The idea is that for such semi-static data streams routing only needs to be done for the first packet. All(More)
This paper links a well-investigated formalism for describing dynamic structured discrete event systems and a modelling methodology for runtime reconfigurable systems. The theory behind dynamic structured discrete event systems is used to back a generic SystemC simulation model derived from and developed for runtime reconfigurable systems. The coupling of(More)
