1. A data processing system, the data processing system comprising:
a first data decoder circuit configured to apply a decode algorithm to a data input to yield a first decoded output, wherein application of the decode algorithm includes multiplying at least one node to node message derived from the data input by a first scaling factor; a second data decoder circuit configured to apply the decode algorithm to the data input to yield a second decoded output, wherein application of the decode algorithm by the second data decoder circuit includes multiplying at least one element of the data input by a second scaling factor; and a scaling factor circuit configured to: modify the first scaling factor based at least in part on the first decoded output, and modify the second scaling factor.
