Abstract
A method of decoding Huffman-encoded data may comprise receiving a symbol associated with the Huffman encoded data, selecting a target group for the symbol based on a bit length value associated with the symbol, associating the symbol with the target group, associating the symbol with a code, and incrementing a starting code for each of a plurality of groups associated with a starting code that is equal to or greater than the starting code of the target group.
