ABSTRACT:
Methods and systems for on-chip processing of data are disclosed. Aspects of the method may include generating a plurality of data processing commands for data compression. A first string of characters may be encoded in one operating cycle utilizing the generated plurality of data processing commands for data compression. The plurality of data processing commands may comprise a branch command, a register moving command, a register setting command, a memory load command, a memory store command, and/or a register compare command. The generated plurality of data processing commands may be stored. At least a portion of the stored data processing commands may be decoded. The decoded portion of the stored data processing commands may be sequenced. The first string of characters may be acquired from a character space. The acquired first string of characters may be matched with at least one existing codeword.
