16.2 Aurora

Overview

The Aurora Protocol is a link layer communications protocol for use on point­-to-­point serial links. It
is intended for use in high­speed (gigabits/second and more) connections internally in a computer
or an embedded system. It uses either 8b/10b encoding or 64b/66b encoding.
