| 20090274382 | ENTROPY DECODING CIRCUIT, ENTROPY DECODING METHOD, AND ENTROPY DECODING METHOD USING PIPELINE MANNER - An entropy decoding circuit, an entropy decoding method, and an entropy decoding method using a pipeline manner are provided. The entropy decoding circuit includes a coefficient register unit, a first entropy decoder, a read/write control circuit, and a second entropy decoder. The first entropy decoder reads a first stream to be decoded to perform a first entropy decoding process thereupon and writes it to the coefficient register unit in an adaptive scan order through the read/write control circuit. 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. | 11-05-2009 |
