Project Petunia (AmigaOS4 JIT emulator) pages updated and extended with a FAQ.
Project Petunia pages (the emulator, that will be used in AmigaOS4) updated and extended with a FAQ.
After a long period of checking forums, chatboards and answering e-mails I decided to add a FAQ part into the project page. I hope I can clean up all the important questions arising in you. If something is not clear enough feel free to write a mail.

Project Petunia FAQ : Comment 14 of 68 | ANN.lu |
Posted by .john on 20-Aug-2002 04:59 GMT | In reply to Comment 7 (JoannaK): Has it ever crossed your mind, that a CPU emulation is extremly CPU dependant ?
Meaning, that there is no much use in 'porting' x86-host code to PPC-host code.
A new system tailored (because targeted) to this 'other' host-CPU is much more
realistic.
To port would mean here to off-line emulate. Why I am saying this ?
I admit this seesm esotheric but have a look:
Porting a x86 program to PPC is easy these days. You change some source parts,
modify instructions.
But we are talking native code here ! I mean, we'd need to port x86 instruction-SET
to PPC-instruction-SET. An emulator just does this: Translating (in this case)
68K instruction-SET to x86 instruction-SET. Now translating the x86 instruction-
SET to PPC instruction-SET comes equal to an offline insource emulation.
This just can't be optimal.
