ABSTRACT:
An embodiment of a method for compressing data includes variable length coding one or more values of control codes generated from dictionary coding the data, wherein the control codes comprise literals and indices, wherein each index comprises a length value and a pointer to previously read in data. An embodiment of a system for losslessly compressing input data includes a modeler operable to determine whether a set of input data matches prior input data, an encoder operable to generate control codes including one or more literal control codes and one or more index control codes, wherein each index control code includes a pointer to a location in the input data and a length value indicating a number of bytes to copy from the location, and wherein the length value is variable length coded.
