Abstract
An apparatus for comparing strings comprises a first and a second set of input registers, a matrix of comparator circuits wherein rows of the matrix correspond to the first set of input registers and columns of the matrix correspond to the second set of input registers, a set of row control registers wherein each register corresponds to a row of the matrix of the comparator circuits, the matrix of comparator circuits configured to compare data provided by the first set of registers with data provided by the second set of registers according to the row control registers, and an error detection circuit configured to compare results from four comparator circuits corresponding to two adjacent rows and two columns of the matrix of comparator circuits. A method that invokes the above mentioned apparatus is also disclosed herein, along with a computer program product corresponding to the method.
