PROBLEM TO BE SOLVED: To speed up decoding processing in a decoding system while decoding a code string encoded by a canocical Huffman coding. SOLUTION: The decoding system is provided with a code length specification part that executes code length specification processing for specifying a code length of the decoding target included in a processing unit. The system is composed so as to instruct the start of the code length specification processing regarding the next-time processing unit to the code length specification, after the code length specification processing regarding a current processing unit is finished, and before the decoding processing is finished.
