Various embodiments of the present invention provide systems and methods for data processing. As an example, a data processing circuit is disclosed that includes: a data detector circuit, a data decoder circuit, and a multi-path circuit. The data detector circuit is operable to apply a data detection algorithm to a data input and a decoder output to yield a detected output. The data decoder circuit is operable to apply a decoding algorithm to a decoder input to yield the decoder output and a status input. The multi-path circuit is operable to provide the decoder input based at least in part on the detected output and the status input.
