    摘要: 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 power usage control circuit. The data detector circuit is operable to apply a data detection algorithm to a data input to yield a detected output. The data decoder circuit is operable to apply a data decode algorithm to a data set derived from the detected output to yield a decoded output. The power usage control circuit is operable to force a defined number of global iterations applied to the data input by the data detector circuit and the data decoder circuit regardless of convergence of the data decode algorithm.
