Abstract
An apparatus and method for minimizing the code length of an input address for at least one for variable length encoded data is claimed. A block of variable length encoded data is read. The block of variable length encoded data is then converted into sub-optimall encoded data. The variable length encoded data is defined in having a prefix portion and a suffix portion. The prefix portion of the variable length encoded data is used to signify the look-up table. The suffix portion of the variable length encoded data is used as an input address for the look-up table.
