There used to be an emulator from Stanford which could

Perhaps you mean IRIX 5.3, the last 5.x, which ran on Indy, Indigo,
Challenge, etc, or 6.4 which was an early special for the Octane and
O2000/Onyx2. There's no IRIX 5.4, at least, not released. It went from
5.3 to the very short-lived 6.0.1, then 6.2 (Indy, Indigo2, etc) 6.3
(first release for O2) and 6.4 (ditto for Octane, Onyx/O2K) and quickly
to 6.5 across the product line.
