PROBLEM TO BE SOLVED: To obtain an information processing apparatus that executes the same information processing as before a fault, continuously without stopping the information processing.SOLUTION: The information processing apparatus includes: first to third multiplexed processing systems 11A to 11C which comprise FPGAs and perform the same information processing on input information input from the outside; a majority determination logic part 15 which make a majority determination on processing results output from respective processing systems; a faulty system detection circuit 20 which detects a processing system wherein fault has occurred; and a reconfiguration part 28 which, when the fault is detected, reconfigures a processing system having the same function as the processing system wherein the fault has occurred, as an FPGA to form a new processing system. Each processing system has a memory, respectively, wherein a circuit state of the processing system is stored. When the fault occurs, the reconfiguration part 28 inputs the same information as circuit states stored in memorys of normally operating processing systems, to the memory of the new processing system, and then causes the new processing system to perform the same information processing as the normally operating processing systems. |
