Abstract:
1. A method for decoding a compressed signal including a plurality of Huffman coded symbols, said method comprising the steps of: (a) reading L bits of said compressed signal into a buffer; (b) Indexing into a row of an extended Huffman look-up table using a portion of the L bits as an indexing address, wherein the extended Huffman look-up table includes information useable for decoding a plurality of encoded symbols in a clock cycle; (c) obtaining at least one decoded symbol from the indexed row of the extended Huffman look-up table; (d) shifting n bits out of the buffer and shifting a succeeding n bits from the compressed signal into the buffer; and (e) repeating steps (b) through (d) until all of the Huffman coded symbols of the compressed signal have been decoded; wherein the extended Huffman look-up table comprises at least one row entry including a plurality of code symbols, said at least one row entry created using a length parameter associated with each of said plurality of code symbols.
