Abstract
A root finding mechanism uses an affine polynomial to find the roots of an error locator polynomial. The affine polynomial is produced from the error locator polynomial and field elements for generating roots of the affine polynomial are determined. Gray code is used to select the field elements used to generate the different roots of the affine polynomial. The roots are tested as possible true roots of the error locator polynomial.
