Diagnosis and reconfiguration is concerned with the detection and location of faulty units and the minimization of the effect of faults within a digital system. This topic is motivated by the need for highly available systems that can continue essential operation, perhaps with degraded performance, when hardware failures occur. In recent years there has been a great progress in development of large-scale integrated (LSI) and microcomputer technology. This led to the consideration of systems of complex elements, such as networks of microprocessors. Today, multiprocessor structures are not only feasible but also highly attractive as cost-effective computer structures. Having a multiplicity of independent processors raises the opportunity for making the system self-diagnosable through interprocessor communication. Also the homogenity of the processors make it possible that after the occurrence of faults the system can reconfigure so that the effect of faults is minimized. In this paper we consider techniques for the design of systems which incorporate diagnostic and computational reconfiguration.
