Nanophotonic Interconnect Architectures for Many-core Microprocessors

Many Core Hardware Architectures

Guest Editors’ Introduction: Silicon Nanophotonics for Future Multicore Architectures

h IT IS OUR pleasure to introduce this Special Issue on Silicon Nanophotonics for Future Multicore Architectures. The need for high-performance and energy-efficient communication between processing cores has never been more critical. The increase in core counts in emerging chip multiprocessors (CMPs) has put more pressure on the communication fabric to support many more streams of high bandwidt...

Analytical Models for Architectural Exploration of Many-core Chip Multiprocessors

The performance of microprocessors has improved drastically in the last few decades. Rapid downscale of the CMOS technology has led to higher operating frequencies and performance densities, facing the fundamental issue of power dissipation. Chip Multiprocessors (CMPs) have become the latest paradigm to improve the power-performance efficiency of computing systems by exploiting the parallelism ...

Ultralow-capacitance opto-electronic devices for femtojoule/bit photonics

Future microprocessors will need an unprecedented many-core architecture providing chip-scale optical communication, and for on-chip-com networks in particular, this architecture should be fully integrated with transmitters, photoreceivers, and other functional nanophotonic devices with low energy consumption. One of the challenges with these opto-electronic devices is to realize a device capac...
