Abstract
The present inventions are related to systems and methods for data processing, and more particularly to systems and methods for performing data decoding including utilization of different scaling values on a portion by portion basis during the data decoding.
Claims20
A data processing system, the data processing system comprising:
- a data decoder circuit operable to apply a data decode algorithm to a decoder input to yield a decoded output, wherein the decoder input includes at least a first portion and a second portion;
- and
- wherein applying the data decoding algorithm to the decoder input includes:
- determining a first condition associated with the first portion;
- determining a second condition associated with the second portion;
- applying a first scaling value to the first portion based at least in part upon the first condition, and
- applying a second scaling value to the second portion based at least in part upon the second condition.
