Review on Fault-Tolerant NoC Designs

Abstract

By benefiting from the development of the semiconductor technology, many-core system-on-chips (SoCs) have been widely used in electronic devices. Network-on-chips (NoCs) can address the massive stress of on-chip communications due to the advantages of high bandwidth, low latency, and good flexibility. Since deep sub-micron era, the reliability has become a critical constraint for integrated circuits. To provide correct data transmission, fault-tolerant NoCs have been researched widely in last decades, and many valuable designs have been proposed. This work introduces and summarizes the state-of-the-art technologies for fault diagnosis and fault recovery in fault-tolerant NoCs. Moreover, this work makes prospects for the future's research.
