What is shoreline bandwidth density?Shoreline bandwidth density is a measure of data transmission capacity per unit length along the edge of a chip, package, or board in semiconductor technology.
Shoreline bandwidth density, typically measured in Gigabits per second per millimeter (Gbps/mm), quantifies the efficiency of data transmission along the edges of semiconductor components. This metric is particularly crucial because chips and packages have limited real estate along their edges where data connections and heat dissipation occur. In-package optical I/O can significantly increase shoreline bandwidth density compared to traditional electrical interconnects, enabling more efficient and powerful computing systems.
The above diagram shows the product of shoreline bandwidth density and energy efficiency of various interconnect solutions plotted versus reach. Shoreline bandwidth density and energy efficiency relates to how efficiently a chip, board, or package uses the limited real estate for interface connections along its edge. Different interfaces also deliver different reach capabilities. Courtesy of Ayar Labs.
