Abstract

In this paper we propose a Modified-Minimal-Connect-Component (MMCC) fault block model, which is improved from Minimal-Connected-Component (MCC) fault block model by decoupling links and nodes, to deal with defective links and nodes for 2D-mesh NoCs. Simulation results show that MMCC achieves higher nodes utilization rate than MCC and almost the same rate as orthogonal convex polygons fault block (OFB) model with faulty nodes only, and the advantage of MMCC becomes more significant when both nodes and links are faulty. For example, it achieves 25% higher nodes utilization rate than OFB with 10% faulty nodes and links in 25×25 mesh topology.
