Networks are emerging as a possible solution for future on-chip interconnects. In this chapter, we show how networks on chip (NoC) are similar to and differ from both off-chip networks (e.g., computer networks) and current on-chip interconnects (e.g., buses). We re-examine their communication services in the context of NoCs. To enable a clean separation between the NoC and IP blocks, we provide...

Many-core chip architectures integrate tens to hundreds of processor cores on a single chip. Recent development of photonic interconnects has made Optical Networks-on-Chips (ONoCs) an attractive technology to overcome the drawbacks of electrical networks-on-chips. With ultra-high bandwidth, low latency, and great energy efficiency, ONoCs enable the designer to build scalable systems. However, p...

In this paper, we propose a new exact closed form mutual inductance equation for on-chip interconnects. We express the mutual inductance between two parallel rectangular conductors as a weighted sum of self-inductances. We do not place any restrictions on the alignment of the two parallel rectangular conductors. Moreover, they could be co-planar or reside on different layers. Most important, de...

This chapter presents a brief overview of some of the major research contributions in the area of VLSI computing with optical interconnects since the early modelings of the 1980s to today’s MEMS implementations. Both free-space and fiber-guided interconnects are covered. Various models and architectures with optical interconnects are shown, and aspects of their algorithmic design are also revie...

—Magnetic domain-wall (DW) has been widely investigated for future memory and computing systems. However, energy efficiency and stability become two major challenges of DW-based systems. In this letter, we first propose exploiting skyrmions as on-chip and inter-chip interconnects for DW-based systems, owing to the topological stability, small size and ultra-low depinning current density. In the...
