Recent remarkable advances in nanoscale silicon-photonic integrated circuitry specifically compatible with CMOS fabrication have generated new opportunities for leveraging the unique capabilities of optical technologies in the on-chip communications infrastructure. Based on these nano-photonic building blocks, we consider a pho-tonic network-on-chip… (More)
—The design and performance of next-generation chip multiprocessors (CMPs) will be bound by the limited amount of power that can be dissipated on a single die. We present photonic networks-on-chip (NoC) as a solution to reduce the impact of intrachip and off-chip communication on the overall power budget. The low loss properties of optical waveguides,… (More)
Packet-switched networks on chip (NoC) have been advocated as a natural communication mechanism among the processing cores in future chip multiprocessors (CMP). However, electronic NoCs do not directly address the power budget problem that limits the design of high-performance chips in nanometer technologies. We make the case for a hybrid approach to NoC… (More)
As multicore architectures prevail in modern high-performance processor chip design, the communications bottleneck has begun to penetrate on-chip interconnects. With vastly growing numbers of cores and on-chip computation , a high-bandwidth, low-latency, and, perhaps most importantly , low-power communication infrastructure is critically required for next… (More)
We present SPINet (Scalable Photonic Integrated Network), an optical switching architecture particularly designed for photonic integration. The performance of SPINet-based networks is investigated through simulations, and it is shown that SPINet can provide the bandwidth demanded by high performance computing systems while meeting the ultra-low latency and… (More)
Active queue management (AQM) is an important function in today's core routers that will be required in the future optical internet core. A recently reported novel architecture for optical packet buffers is extended by implementing necessary AQM functions. The suggested AQM scheme is validated and explore via simulations.
