PROBLEM TO BE SOLVED: To provide a value selection circuit capable of quickly selecting any one of input values, and easily dealing with the increase of the input values. SOLUTION: In the value selection circuit, a comparator 111 outputs a value AB having a value "1" when an input value is A>B, and outputs a value AB having a value "0" when the input value is A≤B. A comparator 112 outputs a value BC showing the comparison result of input values B and C in the same way. A comparator 113 outputs a signal CA showing the comparison result of the input values C and A in the same way. A table 121 of a selection signal output means 12 preliminarily stores the values at the positions of the respective addresses which can be shown by combination of the values of the signals AB, BC, and CA. The table 121 reads the value stored at the position of the address shown by the combination of the values of the signals, and outputs a selection signal OUT 121 having this value. A selector 131 of a selection means 13 selects and outputs the input value corresponding to the value of the selection signal OUT 121. COPYRIGHT: (C)2009,JPO&INPIT
