Abstract: A variable shifter includes: a plurality of shifters that cyclically shift input data having a plurality of bits or cyclically shifted data; and a control unit that selects a shift amount for each of the plurality of shifters in accordance with a predetermined cyclic shift amount. The number of types of the predetermined cyclic shift amount is smaller than the number of bits in the input data, each shifter selects one of a plurality of shift amounts in accordance with the predetermined cyclic shift amount, and the plurality of shift amounts have a combination of shift amounts that differ from one shifter to another.
