Building Many-Core Processor-to-DRAM Networks with Monolithic CMOS Silicon Photonics
TLDR
We introduce a new monolithic silicon-photonic technology, which uses a standard bulk CMOS process to reduce costs and improve energy efficiency, and explore the logical and physical implications of leveraging this technology in processor-to-memory networks. Expand
