DEVICES FOR ENCODING

Provided is a device and a method for encoding and decoding to implement maximum transition avoidance coding with minimum overhead. An exemplary device may comprise a transmitter for a data bus, the transmitter comprising an encoder configured to convert data bursts to be transmitted to the data bus into codewords constituted by symbols, wherein the encoder comprises a logic circuit representing correlations between the data bursts and the symbols, wherein the logic circuit comprises: a plurality of sub-block lookup tables classified according to a number of codeword mappings, wherein the codeword mappings represent correlations between some bit values in the data bursts and the symbols; and a combination lookup table selectively interconnecting encoding results according to the plurality of sub-block lookup tables based on remaining bit values in the data bursts,wherein the encoder is configured to provide the codeword corresponding to the data bursts to the data bus by using the combination lookup table and the plurality of sub-block lookup tables.
