There isn't an emulation layer for AS/400 though, it's native POWER code.
The AS/400 / 'i' are descendants of the System/38 and implement a "Technology Independent Machine Interface". Applications target this high-level interface, rather than the underlying hardware. Before first run (or when they're installed?) applications get compiled from abstract Machine Interface code to native code.
