摘要：
A system for decoding a variable-length codeword includes a buffer circuit storing the codeword, a detection circuit detecting the number of bits of a prefix portion of the codeword by use of a detection table while updating the codeword, an extraction circuit extracting a codeword of a suffix portion of the codeword based on the number of bits of the prefix portion while updating the codeword, and a first decoding circuit decoding the codeword base on the number of bits of the prefix portion and the codeword of the suffix portion.
