    • PROBLEM TO BE SOLVED: To provide a cyclic redundancy check circuit for multi-channel serial communication and a communication system equipped with the circuit. SOLUTION: The cyclic redundancy check circuit for multi-channel serial communication is manufactured in the following method: a generation expression is created which generates a cyclic redundancy check bit satisfying a cyclic redundancy check polynomial of a single channel serial communication system in a first time period; a generation expression is created for each delay time by applying time extended by the number of multi-channels to the generation expressions successively from the first time period; and a circuit corresponding to the generation expression for the longest time period is realized from among the created generation expressions. This invention enables parallel processing for the cyclic redundancy check. The cyclic redundancy check circuit corresponding to the generation expressions includes more exclusive OR operation units than the number of the selected factors other than 0 of the cyclic redundancy check polynomial.
