Abstract
Several different types of look-up tables are available in the present invention. That is, one look-up table is selected for each m-bit dataword according to the number of consecutive 0's at lower digits, which include a lowermost digit, of the n-bit codeword preceding thereto and the encoding is performed by using the selected look-up table. Furthermore, the bit-pattern at the lower digits, which include a lowermost digit, of a current n-bit codeword is replaced according to the number of consecutive 0's at upper digits, which include an uppermost digit, of the n-bit codeword following thereafter.
