Abstract:
An encoding method and apparatus is described. In an encoding method, when a first target sub-block in a target block is obtained, a hash operation is first performed on the first target sub-block. Then, a first hash table is queried for a corresponding hash value according to an operation result, and a corresponding location in a reference block is found according to the hash value obtained by means of query, that is, first reference data is found. The first piece of target data in the first target sub-block is matched with the first reference data, and second target data in the target block is matched with second reference data in the reference block. In this way, an approximate location is predetermined, so that a range in which matching needs to be performed is narrowed, a data compression time is reduced, and data compression efficiency is improved.

Claim (Index 2):
The method according to  claim 1 , wherein before the querying a first hash table according to the first key value, the method further comprises:\n obtaining a reference data block from the reference block according to a first step, wherein each reference data block comprises n digits of reference data, the first target sub-block comprises n digits of target data, and n is a positive integer; and constructing the first hash table, wherein the key value in the first hash table is obtained by performing the hash operation on the reference data block.
