Systems and methods for modified quality based priority scheduling during iterative data processing

摘要

Systems, circuits, devices and/or methods related to systems and methods for data processing, and more particularly to systems and methods for priority based data processing. As one example, a data processing system is disclosed that includes a data detector circuit, a data decoder circuit, a memory circuit, and a scheduling circuit. The scheduling circuit is operable to select one of a first data set and the second data set as a detector input for processing by the data detector circuit.

1. A data processing system, the data processing system comprising:
a data detector hardware circuit operable to apply a data detection algorithm to a detector input to yield a detected output; a data decoder hardware circuit operable to apply a data decode algorithm to a decoder input derived from the detected output to yield a decoded output, wherein application of the data detection algorithm and at least one application of the data decode algorithm is a global iteration; a memory circuit operable to maintain a first data set and a second data set, wherein the first data set exhibits a first quality and a first number of global iterations, and wherein the second data set exhibits a second quality and a second number of global iterations; and a scheduling hardware circuit operable to select one of the first data set and the second data set as the detector input for processing by the data detector hardware circuit, wherein the selection is based at least in part upon a comparison of the first number of global iterations and the second number of global iterations.
