VARIABLE-LENGTH DECODER, VIDEO DECODER AND IMAGE DISPLAY SYSTEM HAVING THE SAME, AND VARIABLE-LENGTH DECODING METHOD

摘要

A variable-length decoder includes a bitstream interface unit and a decoding unit, The bitstream interface unit generates a decoding bitstream for a current decoding process based on an unused decoding bitstream and an input bitstream. The unused bitstream includes unused bits of a previous decoding bitstream. The decoding unit decodes the decoding bitstream to generate a plurality of symbols per clock cycle and provides a next unused bitstream for a next decoding process to the bitstream interface unit.
