PURPOSE:To perform majority operation of high reliability even in the condition that replacement, repair, or the like of arithmetic units is limited. CONSTITUTION:A comparing device 2 classifies operation results to groups having the same values. A weighting means 3 totalizes weighted values indicating reliabilities of respective arithmetic units in each group. A majority arithmetic unit 4 judges the operation result of the group having the largest weighted value to be accurate and outputs it. Weighted values of respective arithmetic units are properly updated based on past actual results or the like of arithmetic units. |
