Abstract

Systems and methods for identifying error bits in encoded data are disclosed. As a part of identifying error bits, encoded data that is provided from a data source and that includes data and parity check portions is accessed. Based on the encoded data, syndromes are calculated, and based on the calculated syndromes, an equation is determined. The roots of the equation are determined and based on the determined roots of the equation, one or more error bits are identified. The error bits are identified using a circuit that presents a binary representation of the roots. The error bits are corrected based on the error bits that are identified.
