ABSTRACT:
To provide a decoding device that compactly stores prefix related information therein compatible to variable-length codes used in various systems. The decoding device includes a register file in which a prefix common portion and a word length of the prefix common portion, prefix individual portions and word lengths of the prefix individual portions, word lengths of suffixes, and an input bit sequence are stored, a bit matching unit that determines a prefix included in the input bit sequence from prefixes generated from the prefix common portion and the prefix individual portions, a codeword computation unit that computes the word length of a codeword included in the input bit sequence using the respective word lengths of the prefix common portion, a prefix individual portion, and a suffix corresponding to the determined prefix, and an index computation unit that computes an index in a symbol table using the respective word lengths of the corresponding suffix and the codeword.
