Evaluation of a distributed fault handler method for MPSoC

The increasing infant mortality and wear out failure rates observed in very deep sub micron silicon technologies is now a major problem for the design of future high-density SoCs. Emerging architectures based on Multi-Processor SoCs (MPSoCs) give the opportunity to exploit the natural redundancy to control the system performance in presence of failures. In this paper we evaluate the impact of a distributed fault-handler strategy on the system in term of cost and feasibility. We also discuss strategies for applying this technique to a distributed MPSoC architecture.
