Abstract

This work investigates the integration of CMOS-compatible optical technology to on-chip coherent buses for future CMPs. The analysis results in a hierarchical optoelectrical bus that exploits the advantages of optical technology while abiding by projected limitations. This bus achieves significant performance improvement for high-bandwidth applications relative to a state-of-the-art fully electrical bus
