Abstract
Provided are systems and methods, including an integrated circuit, for data decompression of data encoded using a fixed-length encoding technique. For a data set where some symbols appear more frequently than others, the frequent symbols can be encoded into a short encoded symbol, and the remaining symbols can be encoded into a long encoded symbol. A decompression circuit can include decoder circuits that, upon receiving a set of input bits, can determine whether the set of input bits include one long encoded symbol or one or more short encoded symbols. The decoder circuit can then decode the one long encoded symbol or the one or more short encoded symbol. The fixed length of the encoded symbols can enable the decompression circuit to output decoded symbols at a same rate at which the circuit receives encoded symbols.
