JIT E-UAE

Cool

50% faster now that's what I call an update !

Wow!

Hurray now we can have 50% slower computers

And again an interesting update:

Nice news :)

JIT is now about 3.3 times faster than interpreted CPU emulation, which seems like a very useful speed-up to me

What a great news! E-UAE will fly on our Sam440ep thanks to this great piece of software that is the JIT emulation!

32 seconds against 108! not bad i think

and 9 seconds with "all optimisations on"

Another idea about strategies for debugging : Did you try to use tools (compiler, specialized tools, ...) to check the code and potential pitfalls ?

He refers that for the winuae config to compare with the x86 JIT.

No, that was how fast WinUAE does the same test on a Intel Core i3 running at 2.27 GHz. But given that his Amiga tests were done on a G3 running at 0.8 GHz, his results are really good!

Even ignoring the extra cache, faster bus & other speed-ups the Intel Core i3 has over his G3, the Intel is at least 2.8 times faster than the G3, while it manages to run the JIT test 3.5 times faster than the G3. That means that our new JIT is about as good as the Intel one, or quite possibly even better.

Another big bug squashed

It’s not surpriseconsidering it’s going to be faster as the 68k to PPC Jit does not need to endien swap and has optimized JIT cache.

PowerPC will be always faster to emulate same big-endian cpu’s then Intel or AMD, AMD and Intel will always be faster at emulating little endien cpu’s, the overhead of translating between big end little endien sucks big time, note power pc has some reverse endien instructions to deal whit it, but I believe its limited to only a few addressing modes, and also it does require assembler optimizing to use this instructions.

And dual / quad cores does not help a lot when your emulating a old single treaded CPU.

The only thing that makes INTEL or AMD faster is higher clock frequency.

Oops, I shouldn't read that in the middle of my job

Great news. Hopefully not long now before some games can be tested.

We are getting there! gogoggogogo

Its great it will be done
