A novel architecture for reconfigurable computing based on a coarse grain FPGA-like architecture is introduced. The basic blocks contain all arithmetical and logical capacities as well as some registers and will be pro-grammable by sequential instruction streams produced by software compiler. Reconfiguration is related to hyper-blocks of instructions. For(More)
Summary form only given. Mechatronic systems request for high reliability, especially in the context of time where mostly hard real-time capabilities are mandatory. May be even stronger requirements regard the robustness against software failures and interdependences from erroneous tasks to others. We propose the concept of robust partitioning for reliable(More)
Mechatronic systems often require hard real-time behaviour of the controlling system. The standard solution for this kind of application is based on the time-triggered approach, and for certain circumstances the schedulability is provable. In contrast to this, the approach in this paper introduces some hardware enhancements that allow first to substitute(More)
This approach modifies a RISC processor by integrating an additional Fetch Look-Aside Buffer (FLAB) for instructions. While the first fetch of any instruction results in normal execution, this instruction is combined in parallel with former instructions for later execution and saved inside the FLAB. The architecture works like a dynamic(More)
In software and hardware development MATLAB and Simulink are used to model cyber physical systems for many years, , especially in automation technology and the automotive industry. Compliance with the required product quality and project efficiency is facilitated by analyzing and transforming Simulink models. The existing API, provided by MATLAB is only(More)
