Claim:
A method of implementing a multi-sectional encoding indexing method, comprising the steps of: providing an m sectional encoding structure including encoding structure values Ā i ″′, with each of the encoding structure values Ā i ″′ having at most 2 2 i varieties; transferring the encoding structure values Ā i ″′ into n encoding structure values Ā i ″ whereupon the encoding structure values Ā i ″ will have k i bits varied, and thus the summation of the k i bits associated with the encoding structure values is equal to n, ( ∑ i = 0 m - 1 ⁢ ⁢ k i = n ) , wherein n stands for an index bit width of the multi-sectional encoding indexing method; adjusting the encoding structure values Ā i ″ into encoding structure values Ā i ′ by using a bit-by-bit AND operation with (2″-1) the encoding structure values Ā i ′ having an n bit width; and determining whether or not the encoding structure values Ā i ′ are transferred into Ā 0 ⊕Ā 1 ⊕...⊕Ā m−1 , and if the encoding structure values Ā i ′ are transferred into the Ā 0 ⊕Ā 1 ⊕...⊕Ā m−1 , then bits of Ā i , from n - ( ∑ j = 0 i - 1 ⁢ ⁢ k j + 1 ) to n - ∑ j = 0 i ⁢ ⁢ k j , will become variable ones, wherein ∑ j = 0 - 1 ⁢ ⁢ k j = 0 and the Ā 0 ⊕Ā 1 ⊕...⊕Ā m−1 , has a characteristic that different output values can be produced as long as the values inputted vary, and have a collision free effect.
