5.1.2.1. Using One Domain with Width Adaptation

When one of the hosts in a system connects to all the agents, Platform Designer creates a single domain with two packet formats: one with 64-bit data, and one with 16-bit data. A width adapter manages accesses between the 16‑bit host and 64‑bit agents. In the following example, two 64‑bit hosts access two 64‑bit agents. One 16-bit host, accesses two 16‑bit agents and two 64‑bit agents. The 16-bit Avalon® host connects through a 1:4 adapter, then a 4:1 adapter to reach its 16-bit agents.
