PROBLEM TO BE SOLVED: To provide an information processing system capable of improving reliability.SOLUTION: An information processing system includes: processing blocks 310A-310C for executing the same processing according to a common input from the outside, and respectively outputting first-third processing results; diagnosis blocks 300A-300C which respectively correspond to the processing blocks; and an external transmitting/receiving block 10α. The processing blocks 310A-310C include reconfigurable circuit portions 319A-319C. The external transmitting/receiving block and each diagnosis block have majority determining portions 14aα, 14b-14d for majority determining the first-third processing results, and fault diagnosis portions 23aα, 23b-23d for diagnosing when an error is in a majority determining result. Each of the fault diagnosis portions carries out processing for sharing fault diagnosis information generated while reflecting an error with other fault diagnosis portions via a first communication portion. |
