    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 Viterbi detector for use in a partial response maximum likelihood (PRML) signal processing apparatus. The Viterbi detector can be used for different partial response (PR) equalizations with different parameters, and can be used for different PRML signal processing apparatuses such as high speed optical disk systems. The Viterbi detector includes an input buffer, a branch metric calculation unit, an add-compare-select circuit, a path memory unit, and a clock buffer. The Viterbi is designed based on a union trellis diagram relation obtained by combining trellis diagram relations associated with the PR equalizations with the parameters. According to the invention, the Viterbi detector has advantages of saving hardware space and conveniently changing PR equalizations with different parameters.

    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.
