Abstract
A method for testing processors includes generating, from a set of input bits, a first set of machine data bits in a first processor and a second set of machine data bits in a second processor dissimilar to the first processor, and comparing the first and second sets of machine data bits to output a first comparison result. The method also includes generating, from a third set of machine data bits, a first and second sets of machine result bits, and comparing the first and second sets of machine result bits to output a second comparison result. The method further includes generating, from a fourth set of machine data bits, a first and second sets of output bits, and comparing the first and second sets of output bits to output a third comparison result. The method also includes determining whether the first and second processors operate substantially similar to each other based on at least one of the first, second, and third comparison results.
