In our approach for developing heterogeneous control systems, we have developed a real-time A/D D/A board called "the Raptor". The Raptor communicates over high speed and highly reliable DS-links (IEEE-1355). To obtain highly accurate analogue conversions, the A/D and D/A converters have a 12-bit resolution. We measured a maximum sampling frequency of 90.5 kHz on each A/D channel. For communication with the rest of the control environment, two 100 Mbit/s DS-links are available. The Raptor forms a part of a heterogeneous multiprocessor closed-loop control environment. This new environment can be used, amongst others, for controlling heavy robot applications. The work on this environment takes place in scope of the JavaPP (Java Plug & Play) project. The software will be developed together with the CJT-library that provides inherent object-oriented and parallel design patterns, according to the CSP paradigm, in Java.
