In this paper, the authors propose a fault-tolerant solution for a buffer less network-on-chip, including an online fault-diagnosis mechanism to detect both transient and permanent faults, a hybrid automatic repeat request, and forward error correction link-level error control scheme to handle transient faults and a reinforcement-learning based Fault-Tolerant Deflection Routing (FTDR) algorithm to tolerate permanent faults without deadlock and live lock. A Hierarchical-Fault-Tolerant Deflection Routing (FTDR-H) is also presented to reduce the area overhead of the FTDR router.
