%E Peter H. Welch, Andr\[`e] W. P. Bakkers %B Proceedings of WoTUG\-21: Architectures, Languages and Patterns for Parallel and Distributed Applications %X 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 converteds have a 12\-bit resolution. We measured a maximum sampling frequency of 90.5kHz on each A/D channel. The maximum sampling frequency of each D/A channel has been measured to be approximately 145kHz. For communication with the rest of the control environment, two 100Mbit/s DS\-links are available. A data transfer rate of 5.57Mbytes/s has been achieved on each DS\-link adapter. 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 JavaPP (Java Plug and Play) project. The software will be developed together with the CJT\-library that provides inherent object\-orientated and parallel design patterns, according to CSP paradigm, in Java.
