Abstract: A method may include at least partially initializing a trellis of an SE engine at least partially based on predetermined state information about a communication channel associated with an incoming data stream; and processing, via the MLSE engine, the incoming data stream to further initialize the trellis and decode the incoming data stream.

Abstract: Disclosed embodiments of the present disclosure relate, generally, to systems, methods, and devices for correction of burst-errors induced during transmission of encoded blocks of information. Some embodiments relate to decoders configured to test candidate corrections on a received block of information and select a candidate correction that best fits the characteristics of burst-errors expected for a type of transmission scheme. Such tested candidate corrections may be selected based on characteristics of burst-errors typically induced for a type of transmission scheme. Some embodiments relate to decoders configured to test candidate corrections for correcting burst-errors and perform standard error correcting techniques such as Reed-Solomon forward error correction techniques. Some embodiments relate to systems, such as serial/deserializer interfaces, that incorporate such decoders.

Abstract: A method may include generating a first computational circuit of a current iteration of a Berlekamp algorithm, the first computational circuit to determine a Berlekamp discrepancy value at least partially based on a current Error-Locator Polynomial (ELP) and observed syndromes; and generating a second computational circuit of the current iteration of the Berlekamp algorithm, the second computational circuit to determine an intermediate value, the intermediate value useable by one or more first computational circuits of one or more subsequent iterations of the Berlekamp algorithm to determine Berlekamp discrepancy values.

Abstract: A method may include: initializing four states of a trellis, the four states corresponding to the four possible symbol levels in PAM4, where a respective initial state starts with an initial score and an empty survivor path; for respective possible transitions between the four initial states and four possible current states of the trellis, determining expected PAM4 symbols; determining error associated with respective transitions based on differences between a received PAM4 symbol and the expected PAM4 symbols; discarding transitions where the error indicates a difference greater than a single signal level, and keep the other transitions; and for respective current state groups of a two state trellis, determining one of the incoming transitions that was not discarded having the highest likelihood of being associated with a transmitted symbol.

Abstract: A method may include generating a status signal, the status signal to indicate a status of Error-Locator-Polynomial (ELP) determination by an ELP determination circuit; and controlling the ELP determination by the ELP determination circuit at least partially responsive to a value of the status signal.
