1964 Recompiling Engine Doc |
1964 probably isn't the most ideal example either, but I guess that might be just due to the fact that emulating a 64-bit CPU on x86 one runs out of registers pretty fast...
Here are some other interesting documents:
The DR Emulator
Just a short article about the 68K dynarec that was included in MacOS when the switched to the PowerPC. It's written by Eric Traut, who is probably the only dynarec celebrity, since he also was responsible for the dynarecs in Virtual Gamestation and Virtual PC.
Shade
This documentation describes a fast SPARC simulator and a lot of ideas are interesting for dynarecs as well.

There also have been two university projects dealing with ARM emulation via dynarec:
ARMphetamine and
Tarmac.
Especially the report on the latter project is highly recommended.
I once wrote a thread hear about dynamic recompilation, but it was a mostly a combination of well-known facts with a little bit of my own ideas thrown in. If you want to take a look anyway:

I tried the link in your profile but it doesn't seem to work...
Unfortunately Dynarec.com is no more since Neil Bradley shut off the server, otherwise I could have provided much more information.
But the dynarec mailing list migrated to Yahoo, if you are interested in more discussion about dynamic recompilation:
Dynarec Group
I guess that's enough for now...
