Hybrid architecture is becoming a promising solution for today’s high-performance on-chip communication networks, commonly known as Networks-on-Chip (NoCs). For example, a mesh-based hybrid on-chip network has wired and wireless routers. The intent is to achieve better performance in low latency, high throughput, and low energy than a traditional wired or wireless mesh NoC. The performance of a hybrid mesh NoC is heavily affected by the positions of the wireless routers in the NoC. This paper proposes a placement strategy for placing a wireless router in a wired Mesh NoC (MoC) into a hybrid MoC. The proposed method involves partitioning an underlying network into multiple equal-size subnetworks. Each subnetwork includes two wireless routers for better connectivity between communicating nodes. The proposed strategy on evaluation of a 32-bit 8 × 8 hybrid MoC shows that the basic performance metrics- latency, network throughput, and energy consumption ranges from 18.64 to 42822 cycles, 5.02–11.23 flits/cycle, and 14.91–34.42 μJ, respectively. Furthermore, results improve packet loss, latency, and throughput metrics up to 96%, 98.36%, and 25.77%, respectively, compared to the wired 8 × 8 MoC. Furthermore, the proposed approach improves latency reduction by 1347% and scales by 15 × than a set of previous methods.

混合架构正在成为当今高性能片上通信网络（通常称为片上网络（NoC））的一种有前途的解决方案。例如，基于网格的混合片上网络具有有线和无线路由器。其目的是在低延迟、高吞吐量和低能耗方面实现比传统有线或无线网状 NoC 更好的性能。混合网状 NoC 的性能很大程度上受 NoC 中无线路由器位置的影响。本文提出了一种将有线网状 NoC (MoC) 中的无线路由器放置到混合 MoC 中的放置策略。所提出的方法涉及将底层网络划分为多个大小相等的子网络。每个子网包括两个无线路由器，以实现通信节点之间更好的连接。所提出的 32 位 8 × 8 混合 MoC 评估策略表明，基本性能指标 - 延迟、网络吞吐量和能耗范围为 18.64 至 42822 个周期、5.02–11.23 flits/周期和 14.91–34.42 μJ，分别。此外，与有线 8 × 8 MoC 相比，结果将丢包率、延迟和吞吐量指标分别提高了 96%、98.36% 和 25.77%。此外，与之前的一组方法相比，所提出的方法将延迟减少了 1347%，并将规模扩大了 15 倍。
