Abstract
An apparatus includes a convergence detector circuit coupled to an error locator polynomial generator circuit. The convergence detector circuit includes at least two computation circuits configured to generate at least two convergence signals based on a mutual error locator polynomial from the error locator polynomial generator circuit and on at least two different sets of syndromes. Each of the different sets of syndromes corresponds to a different one of the convergence signals.
