Abstract
Systems, apparatus and methods are provided for compressing data and decompressing compressed data. A method may comprise receiving an input data block to be compressed, generating a number of occurrences table and a cumulative occurrences table for distinct symbols in the input data block, for each symbol in the input data block, based on the number of occurrences table and the cumulative occurrences table, dynamically obtaining a number of shifts for right-shifting a current state 'x' to encode a current symbol, outputting right-shifted bits to encoded data and obtaining a next state 'x' and obtaining a final state “X” from a last state “x” generated in a final loop.
