Modern material handling systems (MHS) are complex systems which are controlled by various control units on different automation levels. The design of the MHS facility layout and the development of the control units require the application of different CAE tools but simulation and virtual commissioning does currently not play a significant role because… (More)
For covering the real-time characteristics of an automation system during model-based design it is essential to model not only the function but also the behaviour of the control programs running on a real-time controller. This paper introduces an approach to the modelling and evaluation of the functional and time behaviour of Pro-grammable Logic Controllers… (More)
Methodical HW/SW Design of the GSM Speech Transcodec Algorithm We describe the design of the GSM speech transcodec algorithm. Complexity and real time requirements lead to a combined HW/SW design where timing critical parts are identified and realized in hardware. The prototype realization uses a standard PC and a FPGA board.
