    摘要: An integrated apparatus for multi-standard optical media includes a compact disc/digital versatile disc (CD/DVD) processor, a high-definition DVD (HDDVD) processor and a Blu-ray disc (BD) processor; a memory unit connected to the CD/DVD processor, the HDDVD processor and the BD processor to provide a storage resource; and a shared error correction code (ECC) engine for encoding or decoding the CD/DVD data stream, the HDDVD data stream and the BD data stream. Therein, the ECC engine further has a syndrome/parity generator to encode the data stream or to obtain the syndrome information from the data stream; and an erasure generator to obtain the possible error position information from the data stream. Thereby, the complexity and cost of the integrated apparatus can be reduced.

    摘要: A method for decoding multiword information comprises steps (a) to (e). In step (a), a multiword information cluster, e.g., ECC, including high protective codewords, e.g., BIS, and low protective codewords, e.g., LDC, is provided. In step (b), the high and low protective codewords are stored into a first memory, e.g., DRAM. In step (c), the high protective codewords are decoded to generate high protective word erasure indicators showing whether decoding errors occur. In step (d), the high protective word erasure indicators are stored into a second memory, e.g., SRAM. In step (e), the low protective codewords are decoded. In the meanwhile, an erasure bit for a low protective codeword is marked by finding high protective codewords close to the low protective codeword in the multiword information cluster and looking up the high protective word erasure indicators of the high protective codewords close to the low protective codeword.

    摘要: A method for decoding multiword information comprises steps (a) to (h). In step (a), a multiword information cluster including high protective words and low protective words is provided, wherein the multiword information, high protective words and low protective words can be ECC data, BIS data and LDC data, respectively. In step (b), the low protective words are partitioned into multiple groups. In step(c), the low protective words are de-interleaved, so as to generate a low protective word cluster including multiple segments corresponding to the multiple groups. In step (d), any error of the low protective words is detected, so as to generate segment erasure indicators with localities. In step (e), the low protective words and the segment erasure indicators are stored into a first memory, e.g., a DRAM. In step (f), the segment erasure indicators are stored into a second memory, e.g., a SRAM. In step (g), erasure bits of the low protective word are generated based on the segment erasure indicators. In step (h), the low protective words read from the first memory are decoded by means of the erasure bits.

    摘要: A method for computing parity characters for a codeword of a cyclic code successively generates a sum of an output value and a respective message character of a first message section adjacent to parity characters within a first block. The method then successively multiplies a respective sum by corresponding coefficients of a generator polynomial to generate at least one product. The method further successively multiplies a respective message character of every message section other than the first message section by coefficients of a corresponding shift polynomial to generate a plurality of products, before finally, successively summing corresponding products to generate the output value.
