摘要： A maximum a posteriori detector includes a single state metric engine that performs forward and backward processing to produce forward and backward state metrics. The state metric engine includes a plurality of processes that each perform both the forward and the backward processing operations. The system further includes memory that stores the forward and backward state metrics that are produced by the engine in appropriate orders for the forward and backward processing. A number of multiplexers provide the appropriate branch metrics and apriori values to adder strings in each of the processors in accordance with an associate decoding trellis.

摘要： A decoding system includes a timing loop for use in error recovery mode operations, in which “fast decode” bit values that are used for timing recovery purposes in the normal modes of operation are replaced, at an appropriate iteration in the error recovery mode, with detected bit values from an iterative detector. The replacement occurs after a reread operation in which the timing loop maintains lock.

摘要： An iterative decoder is controlled to iteratively decode a block by performing one or more decoding iterations for the block during a predetermined block time. The iterative decoder is further controlled to perform more decoding iterations for the block during a time in which the hardware of the iterative decoder is available, if the block fails to converge to correct data during the predetermined block time. The iterative decoder uses a parity-check matrix and can be configured to process that parity-check matrix for parallel, sequential or a combination of parallel and sequential (“hybrid”) parity constraint updates.
摘要翻译：控制迭代解码器以在预定的块时间期间对块执行一个或多个解码迭代来迭代地解码块。迭代解码器被进一步控制，以便在迭代解码器的硬件可用的时间期间对块进行更多的解码迭代，如果块在预定块时间期间未能收敛以校正数据。迭代解码器使用奇偶校验矩阵，并且可以被配置为处理用于并行，顺序或并行和顺序（“混合”）奇偶校验约束更新的组合的奇偶校验矩阵。
