ADOOM on A600 running 22-35 FPS

[biggun]

The A600 is permanently perpetually stuck in 32-bit mode forever and ever and ever.  There is no way to switch into 64 bit mode.  It can't be downgraded into 24-bit mode.  It can't be downgraded into 16-bit mode.  It is just STUCK at 32-bit mode period.  The End.

Hmm actually this is all not true what you say.
The A600 was shipped with a 16/32 bit CPU runnign in 24bit address mode.

So be default you run 32bit code, and of couse you can also run 16bit and 8bit instructions.,
And default the CPU support 24bit address mode.


The Vampire CPU upgrade which this topic is about now replaces the CPU completely.
The Phoenix is SuperScalar and fully 32bit and of course also offers 32bit address mode.
Now enabling 64bit  addresses in Phoenix takes me a *smile*.
This is would absolutely be possible to turn all your existing old AMIGAs into 64bit systems.

Oh snap! :banana:

Can you go into any more detail about what this would entail?  I assume at minimum every application would need to be re-coded?  Or would it be that existing applications would still run, and you'd just have the option to write 64-bit programs as well?  Sort of like how Windows 64-bit can run either 64-bit or 32-bit software?

[jj]

No.  Wrong.

The reason you don't put 32GB of RAM on an Amiga is because Amiga is just like your Phone.  It is a 32-bit computer and has a hard limit of 4GB of addressable memory space.  So the most you could realistically use on an Amiga is 3GB.

Making new accellerator cards for Amigas in 2015 that have LESS RAM than an old 1990s Amiga is lame from the consumer's perspective.  Amigas already had 256MB of ram waaaaay back in the previous century.  Going backwards is not progress, it is congress.


And btw my W7 PC has had 32GB of ram for over a whole year now.  Why can't my Amiga have 2 lousy GB?

my phone is 64bit

Hey, you can glue an AMD64 chip onto the 68000 and call it a 64bit upgrade!! Just as usefull!! Anything AmigaOS is stuck in 32bit forever, and for some even that is too much.

It is planned that it is compatible so existing software works. To use new features software has to be recompiled and we need adapted compilers. That is already in planning.

[OlafS3]

The lack of features in the OS and limitations in the hardware scare many developers away.

There is Aros 68k that can be adapted to anything because all sources are available

[cunnpole]

I take it there isnt a compatible single chip upgrade to the current 64 MB?

[OlafS3]

Well, lack of RAM is one of the major reasons why we lack a modern featured web browser for AmigaOS3 - modern browsers need more RAM, web pages today are resource hungry, number of open tabs alone is meaningless, try doing some work in them too! Working with gfx requires RAM too - I have done my share of animation on Amiga and know very well how limiting 128MB or even 256MB of RAM can be, and ditto if you do audio work, paging to disk is very annoying and also requires MMU features in the softcore to work - much easier to just have more *real* RAM.

We have discussed that on the apollo forum too. Of course more RAM are nice to have and we had the same discussions there too. The project is a compromise between wishes and what is realistic. We need a affordable and realistic path that neither needs 10 years to do nor millions of dollars to invest so using off-the-shelve components that are tested and sold already are the only chance to get something in near future to a low price. And that limits the options of course. I personal would be for "premium" options later for people who are willing to spend more money but for now it is better to have a "mass-solution" (if we can say that in the small market) than a expensive premium option that is only sold in low numbers. Developers need urgently a better platform with more RAM and more processing power and other new features. I do not know how many of the veterans (or any) will support the new 68k platform again because market has changed a lot in the last twenty years but I know that any developer only seriously look at a platform when there is new hardware available. So I (as many others) wait urgently for new hardware now and we do need it now and not after more years of development.

Another opinion of me that not everyone (expecially in the "NG" community) shares is "Back to the future". "NG" as the idea to move developers and users to a new modern hardware platform has failed, not only most users are active on 68k but also most compilers/dev environments,libraries and software is still 68k so for me the best chance for a future are the combination of real hardware based on FPGA on one side and emulation with UAE running (almost) everywhere on the other.

What do you mean?

[ElPolloDiabl]

I'm pretty sure 64-bit (memory) addressing is different from running 64-bit instructions.
I suppose it would be another speed boost for any software ported to a 64-bit 68k.

Here is a link to the next add-on for the Vampire:  http://www.ebay.com/itm/Cray-1-Supercomputer-Memory-Board-Re-Engraving-Certificate-of-Authentically/111586542735?_trksid=p2047675.c100009.m1982&_trkparms=aid%3D777000%26algo%3DABA.MBE%26ao%3D1%26asc%3D28795%26meid%3Dc556e9e6caa841aba49adc5e0e8a8752%26pid%3D100009%26rk%3D1%26rkt%3D1%26sd%3D251832508033

It won't add that much to the cost...

[cunnpole]

What do you mean?

Like when the rasp pi was upgraded from 256 to 512MB of ram with little extra cost involved. I believe it was a straight part swap.

I do not know if it si possible on the Vampire but the other new cards will be ready off-the-shelve cards so I do not believe that you can add RAM.

[som99]

Give me the core used in the video pretty please with sugar on top, my Vampire 600 board want's it

People should learn to have realistic expections - then the risk for dissapointment is lower.


People also need to make realistic comparisons:
For example:

The ACA500 offer 2 MB memory and about 1.0 CPU MIPS

Igors V600 offers 64 MB fast memory and about 80 CPU MIPS



Realistic expectations is to double the values again.

[Paulie85]

I've never used that benchmarking program you have on the bringup page but why does it give 6985.3 mhz as the cpu speed? I know it will be fast but I don't think that kind of speed is possible.
