To which OS are you referring?
AFAICT, the major OSes on POWER are:
A/IX - native port
OS/400 (later i5/OS, now IBM I)
- For CISC AS/400 systems, MI is translated to IMPI (CISC)
instructions
- For POWER systems, MI is translated to POWER instructions
- There is NO emulation of the IMPI (CISC) architecture
Solaris - native port
Linux - native port
Did/does IBM support other operating systems on POWER?
