<p>After calculation of syndrome by use of syndrome registers [S0 to S3] (15 to 18), the value of the syndrome register (15) is loaded in the syndrome registers (16 to 18), and the values of the syndrome registers (16 to 18), in the data registers [R1-R3] (22 to 24), respectively, when there is a singlet error. By use of the syndrome registers (15 to 18), power operation of ν, ν2, and ν3 is repeated until coincidence detection circuits (25 to 28) detect coincidence of the values of the syndrome registers (15 to 18) with the data registers (22 to 24). A counter (29) is operated in synchronism with the power operation. When the coincidence is detected, the count value is defined as the location of data which includes an error. The error is corrected by assuming the value of the syndrome registers [S0] (15) to be its magnitude.</p> |
