    摘要: A data reuse method with level C+ for block matching motion estimation is disclosed. Compared to conventional Level C scheme, this invention can save large external memory bandwidth of motion estimation. The main idea is to reuse the overlapped searching region in the horizontal direction and partially reuse the overlapped searching region in the vertical direction. Several vertical successive current macroblocks are stitched, and the searching region of these current macroblocks is loaded, simultaneously. With the small overhead of internal memory, the reduction of external memory bandwidth is large. By case studies of H.264/AVC, the level C+ scheme can provide a good trade-off between the conventional Level C and D scheme.

The second entropy decoder reads a second stream to be decoded and performs a decoding process thereupon according to a normalization parameter and whether a normalized coefficient is zero or not. Meanwhile, the normalized coefficient in the coefficient register unit is read out in a fixed scan order through the read/write control circuit to complete the decoding process.

    摘要: An adaptive canonical Huffman decoder including a symbol index generator, a content selector, and a symbol table buffer circuit is illustrated. The content selector outputs a content selection signal. The symbol table buffer circuit reads a corresponding symbol table from a plurality of symbol tables stored in an external memory according to the content selection signal and stores the corresponding symbol table. The symbol index generator stores decoding information of a plurality of encoding tables and selects a corresponding decoding information among all the decoding information according to the content selection signal. Then, the symbol index generator receives a bit stream and decodes the bit stream according to the corresponding decoding information to obtain a symbol index. After that, the symbol table buffer circuit obtains an output symbol from the corresponding symbol table according to the symbol index.
