3.1.2.1. Using One Domain with Width Adaptation

When one of the masters in a system connects to all the slaves, 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 master and 64‑bit slaves.
Figure 81. One Domain with 1:4 and 4:1 Width AdaptersIn this system example, there are two 64‑bit masters that access two 64‑bit slaves. It also includes one 16-bit master, that accesses two 16‑bit slaves and two 64‑bit slaves. The 16-bit Avalon® master connects through a 1:4 adapter, then a 4:1 adapter to reach its 16-bit slaves.
