Software News   Software News : Project Trifolium - dual Motorola 680x0 processor emulation
   posted by Mason on 31-Mar-2006 23:04:06 (6251 reads)
Project Trifolium (the next generation of Petunia) is a dual Motorola 680x0 processor emulation with dynamic recompilation for PowerPC based Amigas.
Dynamic recompilation (or also called just-in-time compilation or simply JIT compilation) is a technique of translation of the emulated processor machine code to an executer processor machine code on-the-fly.
This technique is a common method nowadays, usually used in JAVA applications, and it is also applied in several emulators with success.
Trifolium is not officially part of AmigaOS4.

For more informations and download visit the Trifolium webside.

[staff]Yes, yes it is /me looks at date[/staff]


The target of the emulation is high compatibility with a dual Motorola 68040, without MMU support.

What is ready for now?
The actual version is already running in close cooperation with the interpretive emulation in AmigaOS4.0.
Emulated opcodes:
- all integer opcodes of the 68040, except MMU- and cache-related opcodes,
- all of the 68881/882/68040 FPU opcodes, except: FSAVE. (Including software-only supported 68040 opcodes.)
Addressing:
- all addressing modes which is supported in 68020 and up,
- byte, word, longword, single, double, extended data for the FPU.
Flag emulation: all flags.
At compiling time a low level flag data flow analysis and branch control allows on-the-fly optimalizations on compiled code.
Virtual context switches implemented to the PowerPC native code or the interpretive emulation (fallback), it is called automatically when needed.

This is great, I could not belive the speed that I gained with Trifolium.
Keep up the good work.

When it's running my machine CPU usage almost apears to be idle!

Though how about a further speed boost!

Excellent work, the speed increase is unbelievable, run the installer 1st, then run the Triftool to see it working.

Triftool will not work with Petunia! It is very important to install Trifolium first or you will get the following error message if you start the Triftool before installation:

haha. All the way through reading that, I was like "What is the point of emulating two 68ks, when AmigaOS is multitasking anyway?". You simply wouldn't gain anything.

Then I realised what the date is.

@Mason

The install script does nothing. Not even a "Installation finished" !
You're good as designing but not at writing scripts ! LOL

@d0c

Why is your hamster just standing their holding a soldering iron? There are PPC boards that need to be soldered. Tell that hamster to GET BACK TO WORK!

@all

As it's a dual-processor emulation, shouldn't it be called bifolium? Anyway, this is a very professional release; the installer, the triftool, the website. Even the release date is perfect.
