Knowledge-based disk I/O system design aid

The authors present an interactive knowledge-based disk I/O system-design tool combining the technique of artificial intelligence with the conventional ad hoc method of computer architecture design. This tool reduces the expensive implementation and test recycles of the conventional design method and improves the simple forward design process for system-level design. By combining design and evaluation and using a common set of the knowledge base, user interaction, specification problems and performance estimation errors can be greatly reduced. The tool meets the system design requirements without detailed verification simulation of the design and produces a formal structural format of the design and performance specifications. The tool can assimilate new knowledge as it is developed during design by simply adding that knowledge as a frame or a rule.<>
