Abstract
A method of decoding Huffman-encoded words at the rate of one per clock cycle. The encoded words are formed into two strings of bits, one for odd numbered code and one for even numbered code, and two decoders in parallel are used, each first shifting in a number of coded bits during a first clock period, and converting the Huffman code to data on a second clock period. The two parallel decoders are timed so that the shift cycle of one decoder occurs at the same time as the conversion cycle of the other. Finally, the two streams of decoded data words are combined into one stream. The result is one output data word per clock cycle.
