A novel VLSI architecture for digital multimedia post-processing system is presented. First, the sequence of the post-processing de-blocking filter is modified, and the filter algorithm is optimized. Second, the frames are extended at the upper and left frame boundaries for 8 pixels in depth in order to avoid the irregularity and simplify the control unit. At last a macro block-based together with...
An efficient Huffman decoding method is presented in this paper. This new method first partitions a Huffman tree into subtrees. Then some look-up tables are used to represent these subtrees and the symbols of some subtrees are decoded by direct combinational logic. It is shown that by employing this technique decoding operations become significantly faster, and the memory consumption also becomes...
