Abstract
Wireless network on chip (WiNoC) is one of the promising on-chip interconnection networks for on-chip system architectures. In addition to wired links, these architectures also use wireless links. Using these wireless links makes packets reach destination nodes faster and with less power consumption. These wireless links are provided by wireless interfaces in wireless routers. The WiNoC architectures differ in the position of the wireless routers and how they interact with other routers. So, the placement of wireless interfaces is an important step in designing WiNoC architectures. In this paper, we propose a simulated annealing (SA) placement method which considers the routing algorithm as a factor in designing cost function. To evaluate the proposed method, the Noxim, which is a cycle-accurate network-on-chip simulator, is used. The simulation results show that the proposed method can reduce flit latency by up to 24.6% with about a 0.2% increase in power consumption.
