    • A syndrome computing apparatus includes first syndrome computing circuit 2, 4 for receiving a predetermined number of bits of data (codewords) encoded based on a predetermined generator polynomial and performing a syndrome computation on the data inputted based on the generator polynomial. Shift register 1 delays the data by the predetermined number of bits. Second syndrome computing circuit 3, 5 receives the data delayed by the predetermined number of bits, and performs a syndrome computation on the data inputted based on the generator polynomial. Operating circuit 7, 8 vector-adds modulo 2 a first syndrome outputted by said first syndrome computing means to a second syndrome outputted by said second syndrome computing means. Outputs of said operating means 6, 7 are offered as a syndrome based on the generator polynomial.
