PROBLEM TO BE SOLVED: To provide a shift circuit of which circuit size is reduced by simplifying the circuit part thereof for shifting.SOLUTION: A shift circuit 1 has shift parts 11 to 18 respectively located at the output bit positions of output bit groups. Each of the shift parts 11 to 18 has a first selector 21 and a second selector 22. The first selector 21 selects, from an input bit string, a sub-bit string including a target input bit group output from the output bit positions of the shift parts and a neighboring bit group next to the target input bit group, so that one end of the sub-bit string corresponds to one end of the output bit positions of the shift parts. The second selector 22 shifts the target input bit group included in the sub-bit string selected by the first selector 21 in a first direction on a bit-to-bit basis so that one end of the target input bit group corresponds to one end of the output bit positions of the shift parts. |
