PROBLEM TO BE SOLVED: To provide a CRC check circuit capable of accelerating processing. SOLUTION: The CRC check circuit consists of: parallel shift register groups 11-1 to 11-n, wherein with an output of each FF stage 3 after a data input in a first cycle as an origin, cycles are sequentially incremented, the output of each FF stage 3 in the data input in the 2<SP>k</SP>-th cycle is predicted, and an output logic corresponding to the predicted output can be formed; and a logic circuit network 12 for feeding the respective outputs of the parallel shift register groups back to the parallel shift register groups.
