    The Innovation Cycle Dilemma
    (Informatik 2007 – Informatik trifft Logistik – Band 2, 2007) Lucke, Helmut; Schaper, Daniel; Siepen, Peter; Uelschen, Michael; Wollborn, Michael
    Modern in-car infotainment and navigation systems will incorporate features from the automotive electronics as well as from the consumer electronics. These domains have very different innovation cycles, with effects on the hardware and software development process. The “Innovation Cycle Dilemma” refers to the difficulty in integrating both domains. This paper describes a platform that proved to fulfill the requirements from both domains.

    Model-Based Debugging of Embedded Software Systems
    (Softwaretechnik-Trends Band 31, Heft 3, 2011) Iyenghar, Padma; Pulvermueller, Elke; Westerkamp, Clemens; Uelschen, Michael; Wuebbelmann, Juergen
    Model Driven Development (MDD) has been slowly superseding traditional ways of developing embedded software in the recent decade. In line with the MDD, debugging Real-Time Embedded Software Systems (RTESS) and visualizing their behavior using models such as UML diagrams is becoming a reality. However, the existing MDD based debugging tools for RTESS are not applicable (require significant source code instrumentation, sophisticated debug interfaces, etc) for memorysize constrained RTESS. To address this, we discuss a modelbased debugging methodology for RTESS which aims at overcoming the aforementioned limitations. Using our approach, the target behavior can be visualized in real-time using UML sequence and timing diagrams. We illustrate our approach with a prototype and examples. Performance metrics such as the target monitor size and the instrumentation overhead are discussed.

    A Note on Software Partitioning for Embedded Homogenous Multicore Systems
    (INFORMATIK 2008. Beherrschbare Systeme - dank Informatik. Band 2, 2008) Das, Bhaskar; Polle, Torsten; Uelschen, Michael
    The introduction of homogenous multicore systems for embedded devices in the automotive domain has been started recently. Driver information sys- tems like car navigation are the first application. This paper shows how the soft- ware architecture should be designed in order to use the multicore technology efficiently. We will focus on two principles as scheduling algorithms and parallel programming to partition software in multicore systems.
