%X Network-on-chip (NoC) is a communication framework for multiple cores connected together in a system-on-chip (SoC). Different NoC architectures have provided quality of service (QoS) parameters of best effort (BE) and guaranteed throughput (GT). GT services are provided by having a dedicated connection using circuit switching or connection-oriented mechanism of packet switching. GT traffic is usually preferred for real-time traffic such as video processing and multimedia applications. BE services are provided using packet switching. Cache updates is an example of BE noncritical traffic. In this paper, we implement a novel biologically inspired fault-tolerant algorithm that provides both GT and BE QoS. In order to provide fault tolerance, the router architectures is also updated. The bio-inspired, fault-tolerant techniques are a novel way to provide fault tolerance in NoC. Faults in the NoC arise as the size of the devices are shrinking on the NoC, which include the router, links, and processing elements (PEs), to accommodate the complex communication requirements of applications. The proposed NoC's fault-tolerant methods (synaptogenesis and sprouting) are adapted from the biological brain's robust fault-tolerant mechanisms. From the experimental results, the throughput and bandwidth utilization are dropped by 3.55 and 4.87, respectively, during the recovery from faults. The interflit arrival time and packet network latency are increased by only 7.03 and 22.60, respectively, during the recovery from faults. The algorithm also performs as efficiently as the traditional fault-tolerant techniques. © 2018 Institute of Electrical Engineers of Japan.
