Abstract
A forward error correction decoder and method of decoding a codeword is provided. The decoder comprises a convergence processor for estimating an expectation of codeword convergence. The convergence processor is configured to calculate a first value of a figure of merit; calculate a second value of the figure of merit; combine the second value of the figure of merit and the first value of the figure of merit to produce a progress value; compare the progress value of the decoding to a progress threshold; and increase a maximum number of iterations of the decoder if the progress value is greater than the progress threshold. The maximum number of iterations may be initially set to a low number beneficial for power consumption and raw throughput. Increasing the maximum number of iterations devotes additional resources to a particular codeword and is beneficial for error rate performance.
