Building Manycore Processor-to-DRAM Networks with Monolithic Silicon Photonics

Published: 26 August 2008 Publication History

Abstract

We present a new monolithic silicon photonics technology suited for integration with standard bulk CMOS processes, which reduces costs and improves opto-electrical coupling compared to previous approaches. Our technology supports dense wavelength-division multiplexing with dozens of wavelengths per waveguide. Simulation and experimental results reveal an order of magnitude better energy-efficiency than electrical links in the same technology generation. Exploiting key features of our photonics technology, we have developed a processor-memory network architecture for future manycore systems based on an opto-electrical global crossbar. We illustrate the advantages of the proposed network architecture using analytical models and simulations with synthetic traffic patterns. For a power-constrained system with 256 cores connected to 16 DRAM modules using an opto-electrical crossbar, aggregate network throughput can be improved by ~8-10x compared to an optimized purely electrical network.
