PROBLEM TO BE SOLVED: To realize a generator polynomial arithmetic circuit having a small area and a high data transmission capacity generating an error detection code in a non-split frame and a spit frame. SOLUTION: A circuit generating an error detection signal for the header in a frame and an error detection signal for the split frame header in a split frame, and a circuit generating an error detection signal for the data in a non-split frame and an error detection signal for the split data in the split frame are communalized. Furthermore, a circuit generating an error detection code for the header and data in a split original frame is also provided. COPYRIGHT: (C)2004,JPO
