Abstract
A dependent relation of operations is extracted from an operation string expressing an operation specification, and thus the dependent relation of operations is created. Connecting relations between arithmetic units constituting an initial circuit construction of a logic circuit are extracted, and thus the connecting relations of the arithmetic units and the corresponding dependent relation of operations are created. Basic conversion rules are applied to the dependent relation of operations, new conversion rules are prepared, and thus conversion rules are created. The conversion rules are repeatedly applied to the dependent relation of operations for optimization, and optimized dependent relation of operations is created. An optimized operation string is prepared from the optimized dependent relation of operations, and an optimized operation string is obtained.
