Various embodiments of the present invention provide systems and methods for data processing. For example, a data processing system is disclosed that includes a data decoder circuit. The data decoder circuit is operable to: apply a decoding algorithm to a decoder input on a first decoder iteration to yield a first decoder output; compress an output derived from the first decoder output to yield a compressed decoder output; de-compress the compressed decoder output to yield a second decoder output; and apply the decoding algorithm to the second decoder output to yield a third decoder output.
