PROBLEM TO BE SOLVED: To shorten time required for reconfiguration and continue an operation of a section except failure sections in a logic integrated circuit which reconfigures a reconfigurable circuit into functions of a fixed circuit when a failure occurs in the fixed circuit. SOLUTION: Fixed circuits (2, 3, 4 and 5) are divided into a plurality of function circuit blocks (2-1, 2-2 and 2-3), and the function circuit blocks are connected with programmable buses (14-1 to 14-4), and reconfigurable circuits (6-1 to 6-3) are provided, which correspond to the function circuit blocks (2-1 to 2-3), respectively. The area of the reconfiguration is limited to blocks including failure sections, and accordingly alternate processing is finished in a short period. In an area not affected by the alternate processing, an operation can be continued during the alternate processing. COPYRIGHT: (C)2007,JPO&INPIT
