Abstract

As advancements in CMOS technology trend toward ever increasing core counts in chip multiprocessors for high-performance embedded computing, the discrepancy between on- and off-chip communication bandwidth continues to widen due to the power and spatial constraints of electronic off-chip signaling. Silicon photonics-based communication offers many advantages over electronics for network-on-chip design, namely power consumption that is effectively agnostic to distance traveled at the chip- and board-scale, even across chip boundaries. In this work we develop a design for a photonic network-on-chip with integrated DRAM I/O interfaces and compare its performance to similar electronic solutions using a detailed network-on-chip simulation. When used in a circuit-switched network, silicon nanophotonic switches offer higher bandwidth density and low power transmission, adding up to over 10× better performance and 3-5× lower power over the baseline for projective transform, matrix multiply, and Fast Fourier Transform (FFT), all key algorithms in embedded real-time signal and image processing.
