Abstract
An intelligent disk drive employing a controller which performs high speed error correction and miscorrection detection using a finite field processor. The error correction code is defined over a finite field and the error detection code is defined over an extension field of the finite field. The finite field processor performs calculation over both the finite field and extension field to provide high speed error correction and correction validation.
