Abstract
Systems, devices, and techniques relating to signal decoding are described. A describe device includes decoder circuitry configured to selectively update variable and check nodes to decode received information associated with a codeword, and selectively update a first group of the variable nodes and a first group of the check nodes in a first clock cycle; and look ahead circuitry configured to access, in the first clock cycle, a second group of the check nodes that are associated with a second group of the variable nodes, and generate node selection information, based on the second group of the check nodes, to indicate whether one or more variable nodes of the second group of the variable nodes are to be skipped or processed by the decoder circuitry in a second clock cycle based on their respective one or more likelihoods of being changed.
