In computer systems the base elements (CPU, memory, and peripherals) are connected together via busses. As there are many different computer applications, there are also many different bus structures. Attempts have been made to standardise bus structures in order to simplify the process of selection for computer engineers. However, this is difficult because no single bus system can fit all applications. Some bus structure becomes more widely used than the others. Defining a bus structure requires the definition of both the physical medium and the information protocol.

Our experts on Real-Time Systems take part in the international standardisation activity of IEEE, ESONE and VSC (VME Steering Committee), and develop boards and systems based on international standards within the frame of scientific collaboration. Our main strength is designing intelligent, microprocessor-, microcontroller-, or DSP-based systems.

Our researchers worked in the development and realisation of the data-acquisition system of the EUROBALL (EB) project. EUROBALL is a European collaboration to build a highly efficient g-ray spectrometer for nuclear spectroscopy. The EUROBALL Experiment, produces a data stream with a total rate: 30 Mbyte/s. The data processing will be performed in a cluster of workstations. It was designed and implemented a DSP-driven front-end Dual-Port-Memory together with KFKI-RMKI (Budapest, Hungary) and INFN-LNL (Legnaro, Italy).

We participated in a European Union research project, called COPRODES (CAD system for automatic design of FPGA-based communication processors). Partners of the project are University Passau, Riga Aviation University, Technical University of Prague, Technical University of Budapest, ASIC Centrum Prague and an other department of KFKI-MSZKI. The input of the CAD system will be a timing diagram and the output an FPGA (Field Programmable Gate Array) chip (mainly Xilinx -based).

As an industrial application of our DSP - based boards have been developed, an intelligent field-oriented asynchronous motor control system was designed. Asynchronous motors require very complex control algorithms because there is no linear relationship between the stator current and either the torque or the flux. Induction motors can successfully replace the more expensive DC motors using a special control method, called field-oriented theory.
