The BiNoC allows each communication channel to be dynamically self-configured to transmit flits in either direction in order to better utilize on-chip hardware resources. This added flexibility promises better bandwidth utilization, lower packet delivery latency, and higher packet consumption rate at each on-chip router. In this Thesis, a novel on-chip router architecture supporting the self-configuring bidirectional channel mechanism is presented. It is shown that the associated hardware overhead is negligible. Cycle-accurate simulation runs on this BiNoC network under synthetic and real-world traffic patterns demonstrate consistent and significant performance advantage over a conventional mesh grid NoC architecture equipped with hard-wired unidirectional channels. |
