    • Various embodiments of the present invention are related to methods and apparatuses for decoding data, and more particularly to methods and apparatuses for multi-level layered LDPC decoding. For example, in one embodiment an apparatus includes a variable node processor and a check node processor. The variable node processor is operable to generate variable node to check node messages and to calculate perceived values based on check node to variable node messages. The check node processor is operable to generate the check node to variable node messages and to calculate checksums based on variable node to check node messages. The check node processor includes a min finder circuit operable to identify a minimum, a next minimum and an index of minimum value in the variable node to check node messages. The variable node processor and check node processor are operable to perform layered multi-level decoding.
    • 本发明的各种实施例涉及用于解码数据的方法和装置,更具体地涉及用于多级分层LDPC解码的方法和装置。 例如,在一个实施例中,装置包括可变节点处理器和校验节点处理器。 可变节点处理器可操作以生成变量节点以检查节点消息,并且基于校验节点到可变节点消息来计算感知值。 校验节点处理器可用于将校验节点生成到可变节点消息,并且基于变量节点来计算校验和以检查节点消息。 校验节点处理器包括可用于识别可变节点中的最小值,下一个最小值和最小值的索引以检查节点消息的最小取景器电路。 可变节点处理器和校验节点处理器可操作以执行分层多级解码。
