Systems and methods for FAID follower decoding

摘要

Systems and method relating generally to data processing, and more particularly to systems and methods for decoding information. Some disclosed systems include a first data decoding circuit, a second data decoding circuit, and a data output circuit. The second data decoding circuit is coupled to the first data decoding circuit and the data output circuit. The second data decoding circuit is operable to apply a finite alphabet iterative decoding algorithm to the first decoded output to yield a second decoded output.

1. A data processing system, the data processing system comprising:
a first data decoding circuit operable to apply a low density parity check decoding algorithm to a decoder input to yield a first decoded output; and a second data decoding circuit coupled to the first data decoding circuit and a data output circuit, wherein the second data decoding circuit is operable to apply a finite alphabet iterative decoding algorithm to the first decoded output to yield a second decoded output, and wherein the second decoded output is only provided to one or both of the data output circuit or the second data decoding circuit.
