Abstract

The massive integration of cores in multi-core system has enabled chip designer to design systems while meeting the power performance demands of the applications. Wireless interconnection has emerged as an energy efficient solution to the challenges of multi-hop communication over the wireline paths in conventional Networks-on-Chips (NoCs). However, to ensure the full benefits of this novel interconnect technology, design of simple, fair and efficient Medium Access Control (MAC) mechanism to grant access to the on-chip wireless communication channel is needed. Moreover, to adapt to the varying traffic demands from the applications running on a multicore environment, MAC mechanisms should dynamically adjust the transmission slots of the wireless interfaces (WIs). To ensure an efficient utilization of the wireless medium in a Wireless NoC (WiNoC), in this work we present the design of prediction model that is used by two dynamic MAC mechanism to predict the traffic demand of the WIs and respond accordingly by adjusting transmission slots of the WIs. Through system level simulations, we show that the traffic aware MAC mechanisms are more energy efficient as well as capable of sustaining higher data bandwidth in WiNoCs.
