Systems and methods for providing lossless data compression and decompression are disclosed which exploit various characteristics of run-length encoding, parametric dictionary encoding, and bit packing to comprise an encoding/decoding process having an efficiency that is suitable for use in real-time lossless data compression and decompression applications. In one aspect, a method for compressing input data comprising a plurality of data blocks comprises the steps of: detecting if the input data comprises a run-length sequence of data blocks; outputting an encoded run-length sequence, if a run-length sequence of data blocks is detected; maintaining a dictionary comprising a plurality of code words, wherein each code word in the dictionary is associated with a unique data block string; building a data block string from at least one data block in the input data that is not part of a run-length sequence; searching for a code word in the dictionary having a unique data block string associated therewith that matches the built data block string; and outputting the code word representing the built data block string.
