ABSTRACT:
Methods and systems are provided for dynamically compressing and decompressing a data stream in a manner that facilitates hardware implementation. In one aspect, a compression system identifies literal data sequences of variable length in the data stream and characterizes each literal sequence with an indicator that is inserted into the data stream. Sequences that repeat previous sequences in the data stream are identified and replaced with codes characterizing the repeating sequence. Another aspect provides a decompression method and system for removing indicators inserted by the compression system and replacing codes in the data stream with the repeating sequences characterized by the codes.
