These proceedings comprise the contributions of scientists, most of them from the USSR Academy of Sciences and the Siemens AG, Research and Development Department, to a joint meeting on advanced topics of information processing. The joint symposium, held in Moscow in June 1990, provided a platform for exchanging results and discussing the most recent advances in the fields of information processing, software and systems design automation. The symposium dedicated to information processing and software covered a broad range of different aspects with a focus on AI, CASE, and human interfaces. Special topics included artificial intelligence, machine learning, image and speech processing, and multimedia dialogue techniques. The second symposium covered concepts, approaches, and implementation aspects as well as future trends concerning systems design automation, especially for VLSI circuits. Major topics were hardware synthesis and hardware specification, physical design, testing aspects and simulation, framework and cellular automata.
