IPC: H03M13/15
Filed: 1998-10-29
Abstract: In a Reed-Solomon encoding device which produces, for example, a Reed-Solomon code of 4 bytes for a data signal of 16 bytes, the Reed-Solomon encoding device includes a signal separating circuit (100) which separates the input signal into two signals A and B which are successively outputted in a time division fashion.  In synchronism with the output of these signals, an octal counter (1) is counted up.  In response to the two separated signals outputted from the signal separating circuit (100), coefficients of respective terms of a remainder obtained by dividing the data signal by a generator polynomial  are classified into even-number order ones and odd-number order ones to be calculated in parallel. The even-number order coefficients and the odd-number order coefficients are supplied to selectors (2) and (3) as signals C and D, respectively.  The selectors (2) and (3) output the signals from the signal separating circuit (100) when the counter (1) has a count value between 0 and 5 and the signals C and D when the count value is 6 or 7.
