1. A data processing system, the system comprising:
a layered decoder circuit operable to apply a data decode algorithm to a first layer of a decoder input to yield a first set of hard decision data and a first syndrome, and to a second layer of a decoder input to yield a second set of hard decision data and a second syndrome; a data perturbation circuit operable to maintain a list of continuous layers exhibiting a zero value syndrome, wherein the list of continuous layers exhibiting a zero value syndrome includes hard decision data for each layer in the list.
