Today many applications require high-speed communications. To provide for the protocol processing with efficient hardware and software the use of a flexible and efficient platform becomes very import for the high-speed communications networks. In this paper we first describe a top-level view of the implementations platform for handling communication(More)
The ongoing advances in semiconductor technology are the en-abler for complete System on Chip (SoC) solutions. In this SoC domain Digital Signal Processors (DSPs) are employed to carry out software driven digital signal processing tasks. Although DSPs could still be modified in the SoC domain, they are mainly employed as fixed DSP cores. Possible(More)
Retargetability allows an easy adoption of a simulator on different processor architectures without a time consuming redesign of all tools. This is evident for an efficient HW/SW codesign. In this paper we describe a tool set for fast and easy simulation of processor architectures based on a retargetable simulator core. This approach helps to reduce the(More)
In this article we present the concept of a FPGA-based GPS receiver architecture with the aim of providing a framework for investigating new receiver architectures for current and upcoming GNSS standards. This development system facilitates researchers to prove new receiver concepts using real signals, which nowadays can only be simulated using tools such(More)
In diesem Erfahrungsbericht aus der Telekommunikationsbranche wer-den aktuelle Problemfelder der Unternehmensberatung zum Requirements Engineering vorgestellt. Ursachen der Problemfelder werden analysiert (vorhandene Pro-zesse in Unternehmen, mangelnde Toolunterstützung, Enterprise Mobility als zent-raler Faktor für das RE). Die unzureichende Verbindung des(More)

The german term "Beratung" (Counselling) with it's widespread meaning has led to misunderstandings between different professions. Therefore Counselling is defined to be an autonomous area within therapeutic, social, and psychosocial work. The still common perspective which views counselling as a "small" therapy approach derived from therapeutic theory and(More)
