英文摘要： Aiming at the communication energy and latency problem in large scale many-core processors, this project carries out the research on design methodology of acceleration network based optical-electrical hybrid 3D interconnect architecture from three aspects, including topology design, traffic path selection strategy and topology reconfiguration. This project studies the topology generation and optimization method of acceleration network based optical-electrical hybrid network-on-chip, in order to balance the bandwidth distribution and improve the whole performance. Based on the power and latency model of optical and electrical links, power and latency differentiated path selection strategy will be studied, in order to determine how the global and local traffic will be delivered while still maintain traffic balance in optical and electrical subnet. Aiming at the high static power consumption of the optical link, fine granularity reconfigurable optical-electrical hybrid network is investigated to fit for varied global communication requirements of different applications. Based on the research on the above-mentioned key problems, it is expected that to lay a better theoretical foundations for constructing high throughput, low latency and low energy consumption interconnection architecture for many core processor.
