“…However, some works consider fault tolerance and congestion control because both significantly affect NOC performance. Gupta et al [48] focuses on both congestion and fault and proposes "σLBDR" as an improvement of uLBDR to handle the varying level of congestion in NoC. σLBDR can address congestion and fault by using 16 σ-bits for congestion of two-hop nodes to minimum information in the routing table.…”

Recent advances in very-large-scale integration (VLSI) technologies have offered the capability of integrating thousands of processing elements onto a single silicon microchip. Multiprocessor systems-on-chips (MPSoCs) are the latest creation of this technology evolution. Network-on-Chip (NoC) is a scalable and promising interconnection solution used by MPSoCs to achieve high performance. Routing algorithms provide a path to a packet toward the destination. For this, these algorithms should exhibit two characteristics. First, the route selection function should provide enough degree of adaptiveness to avoid network congestion. Second, it should not offer stale information on network congestion status to the neighboring routers. Many researchers have investigated network congestion and proposed techniques to control/avoid congestion. Such congestion avoidance-based algorithms significantly improve NoC performance. However, they may result in hardware overhead for side network implementation to collect congestion status. This paper reviews the selection strategies used to reduce congestion in NoC and classifies them on the technique adopted to handle and propagate congestion information. Additionally, this paper provides the implementation and analysis details of some state-of-art selection methods.

“…As a clear routing method is formulated and implemented, Dt-NoC proves it is deadlock and live-lock free as it uses adaptive approach. As XY routing algorithm is simpler and fast [9,10], in this proposed work XY routing algorithm is taken as basic reference [11]. Dt-NoC is very much reliable to modify for any topology.…”
