- Abstract:
- The importance of power consumption in high performance multiprocessors, combined with power reduction capability of on-chip optical interconnects, offers optical network-on-chip (ONoC) as a new technology solution which can deliver considerably higher bandwidth and lower latencies with significantly lower power dissipation than an interconnection network based only on electronic signaling. An on-chip network should be able to support multicast communications efficiently whether it is an optical or electrical network. On the other hand, multicast communications in optical networks-on-chip has been implemented using shared bus which is not scalable. Moreover, most of optical on-chip architectures use electronic transactions to create optical paths; which increases latency and power consumption. An all-optical network-on-chip is able to eliminate electrical transactions and greatly reduce delay and power dissipation. In this thesis, an all-optical and scalable NoC is proposed which implements multicast communications with low latency and low power consumption. The optical data transmission is done using passive optical switching elements and is done without control network. A behavioral simulator has been developed to evaluate the efficiency of the proposed architecture. Also, the proposed ONoC has been compared to Corona architecture and the architecture based on 2D-MM topology in 22 nm CMOS process technology. The results show that the proposed ONoC has 69% and 76% lower average latency in comparison to these architectures respectively
