Abstract
In one embodiment, a Chien search circuit includes a plurality of evaluation circuits, each configured to sequentially evaluate possible roots αin a respective subset of possible roots of an error location polynomial (Λ(x)). Each evaluation circuit includes a respective sub-circuit for each of a plurality of coefficients λ(0≦i≦T) of the error location polynomial Λ(x) having T+1 coefficients. Each sub-circuit is configured to calculate one term of the error location polynomial for each possible root αin the respective subset of possible roots. Each evaluation circuit is configured to evaluate the error location polynomial for each possible root in the respective subset of possible roots, as a sum of the terms calculated by the plurality of sub-circuits.
