<p><P>PROBLEM TO BE SOLVED: To provide a decoding accelerating apparatus for a variable length code, in which a decoding speed of an entire variable length code decoder can be accelerated while using a decoding method for differentiating decoding of a long codeword and decoding of a short codeword. <P>SOLUTION: A decoding accelerating apparatus includes: a codeword identification unit configured to determine in an input code segment is a short codeword; and a short codeword decoding accelerating unit configured to calculate code segment request information for immediately requesting the next input code segment so as to request the next input code segment by acquiring the code segment request information before perfectly decoding the decoding processing waiting codeword, when it is decided that the decoding processing waiting codeword is the short codeword by the codeword identification unit. The decoding accelerating apparatus for a variable length code is applied to e.g., a variable length code decoder and by accelerating decoding of a short codeword which may occur highly frequently, a decoding speed of the entire variable length code decoder can be accelerated. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
