Abstract :
A novel approach to the identification of a faulty processing element, based on an analysis of the compressed response of the system, is proposed. The test response is compressed first in space and then in time, and a faulty processing element is identified by a hard-decision decoding of the corresponding space-time signature. The overhead analysis and the solution for the hardware minimization problem are presented for several important classes of systems. The proposed method results in considerable hardware savings
