Various embodiments of the present invention provide systems and methods for data processing. For example, a data processing circuit is disclosed that includes an increased iteration enable signal, a first detector circuit, a second detector circuit, and a data decoding circuit. The first detector circuit receives a data set and performs a data detection on the data set to provide a detected data set. The data decoding circuit receives a derivative of the detected data set and performs a decoding process to provide a decoded data set. The decoded data set is provided to the second detector circuit based at least in part on an assertion level of the increased iteration enable signal.
