Abstract
A logic integrated circuit reconfigures a reconfigurable circuit to a circuit having the function of a fixed circuit at the time of a fault in the fixed circuit. The fixed circuits are divided into a plurality of functional circuit blocks, which are connected to programmable buses. Reconfigurable circuits corresponding to each functional circuit block are provided. In this configuration, the range of reconfiguration is limited to the block including the defective portion, so substitution processing is completed within a short time. Further, in the range which is not affected by the substitution processing, the operation can be continued even during the substitution processing.
