Abstract:
1. A method for generating a decode table comprising: generating a first table having a plurality of entries, each entry including a plurality of fields, a first field comprising a value selectively representing a code word of a plurality of code words in a codetable or a portion of a code word of said plurality of code words, a second field comprising a length of a code word, and a third field comprising a difference of a length of a codeword and a value for selectively shifting a code word, wherein a shifted codeword is matched against a value in the first field of one or more entries in the first table; and generating a second table using values in the entries of the first table, the second table operable for decoding a bitstream encoded using said codetable, the step of generating the second table comprising: if a value in the first field in an entry of the first table corresponds to a code word and a value in the second field of the entry corresponds to the length of the code word in the first field in the entry of the first table, setting a result tag in a first portion of an entry of the second table to a first value, and setting a decode result corresponding to the code word in a second portion of the entry of the second table.
