Due to shrinking transistor geometries, on-chip circuits are becoming vulnerable to errors, but at the same time on-chip networks are required to provide reliable services over unreliable physical interconnect. A Connection Oriented Stochastic Routing (COSR) algorithm has been used on one NoC platform that provides excellent fault-tolerance and dynamic reconfiguration capability. A probability model has been built to analyze the COSR algorithm. According to the model, the performance may be improved by implementing a self learning mechanism in each router.
