Abstract
Methods and systems for improved lookup table mechanism for Huffman decoding are provided and may include selecting, based on a plurality of entropy encoded bits from a received bitstream, one of a plurality of codewords that is indexed according to a specific length and that points to all entries which include the specific length. The plurality of entropy encoded bits from the received bitstream may be matched with at least one of the entries that include the specific length. The entries that include the specific length may be stored in a table in memory. A value of the plurality of entropy encoded bits may be compared with the selected one of the plurality of codewords that is indexed according to specific length. The plurality of entropy encoded bits from the received bitstream may be decoded based on the matched at least one of the entries comprising the specific length.
