Abstract
A variable length decoder and its decoding method utilizing a reordered index decoding look-up-table, and that is utilized to incorporate a plurality of decoding LUT's into a single reordered index decoding LUT for use in decoding by making use of the output correlation rule obtained through integrating a plurality of decoding LUT's. Thus, when proceeding with the variable length decodings, the multiplexer has only to select the correct reordered index value from among a plurality of reordered index values as based on the previous decoding results, and then find out the corresponding remapping index value and compensation value, thus searching and obtaining the corresponding reordered index output result in the reordered index decoding LUT through utilizing the remapping index value, hereby obtaining the output result through proceeding with the operations required by making use of the compensation value.
