Abstract
Exemplary system, method and computer-accessible medium for testing a multi-core chip can be provided which can have and/or utilize a plurality of identical cores. This can be performed by comparing each core with as many as at least the number of spare cores plus 1 using a comparator; the number of comparators can equal the total number of cores multiplied by one-half the number of spare cores plus 1. A mismatch between two cores can identify at least one of the two cores as defective and a perfect match between two cores can identify both cores as not defective. The multi-core chip can fail the test if the number of defective cores can be greater than the number of spare cores.
