Apparatus having a plurality of programmable logic processing units for self-repair

An information processing apparatus comprising:

• a logic processing unit formed as a logic circuit for realizing a predetermined function, said logic circuit comprising a plurality of logic forming elements;
• a plurality of spare logic forming elements;
• data holding means for holding logic circuit forming data of said logic processing unit;
• fault detecting means for detecting a fault occurrence in said logic processing unit;
• fault logic element diagnosis means for diagnosing a logic forming element related to the fault occurrence in said fault logic processing unit;
• reconfiguring means for reading said logic circuit forming data regarding said logic processing unit when said fault detecting means detects a fault occurrence in said logic processing unit and for calculating reconfiguration data, based on said logic circuit forming data, to reconfigure said spare logic forming elements with the logic forming elements, except the logic forming element diagnosed by said fault logic element diagnosis mean, based on said reconfiguration data calculated by said reconfiguration data computing means, so as to have the same function as that of said logic processing unit.
