11. The method of claim 10 , further comprising calculating a coded operation difference value.
12. The method of claim 11 , further comprising:
judging whether the coded operation difference value is greater than a preset value; and
using the 10-bit sequence obtained through complementing a 10-bit codeword as a coding result corresponding to the 9-bit source data when the coded operation difference value is greater than the preset value.
13. The method of claim 10 , wherein at least a portion of the 10-bit sequences correspond to unbalanced sequences, wherein the unbalanced sequences have current operation difference values that are not equal to zero, and wherein the Hamming distance detection is performed for each of the unbalanced sequences based at least in part on identifying a minimum Hamming distance.
