Portable GFX Chipsets for Amiga?
« on: June 01, 2014, 06:57:36 AM »
I was wondering why it wouldn't be possible to use one of the graphics chip sets from a mobile device as a low cost video expansion option that would work even on a 600?

a) where you gonna place it in an A600 ? Only options with full addressrage are PCMCIA (o.k) or clipped ontop of the 68k (bad cos you will need an accel)

b) who is gonna write drivers for such a beast ?

c) what kind of stuff do you plan to do on that A600 that won't be better served with an IndivisionECS ?

Pretty much all SW that utilizes a full GFX-card, also cries out for an 040 better 060 and will probraly run even better on a Morphed PowerMac worth 20p.
1. Make an announcment.
2. Wait a while.
3. Check if it can actually be done.
4. Wait for someone else to do it.
5. Start working on it while giving out hillarious progress-reports.
6. Deny that you have ever announced it
7. Blame someone else

If you want better GFX out on the A600 then
the next Vampire might be an option for you.
It comes with fast CPU and with RTG/Video-out

Even the open Unix projects has big problems with this because of the lack of documentation. PowerVR and Mali I guess are the chips one would be looking into.

So the documentation is in essence one early step to evaluate the feasibility.

When you start thinking about those GPUs, and the fact that they are often incorporated into ARM processors, then the next logical step is full emulation.
So why connect it to an Amiga?

Kronos is right.
It is simpler to move to an NG system.

Rather than blast the idea I'd suggest looking into open source mobile drivers like http://limadriver.org/ and the Raspberry Pi's GPU http://www.broadcom.com/products/BCM2835

It might have an ARM onboard but it's not mindblowingly fast. There are also CPU-less GPUs from Broadcom that could be used. So it might be feasible but it would probably be a large project for a hobbyist.

I'm not trying to "blast" the idea, it just seems a little weird to use a device with a processor that runs at several hundred megahertz to aid another device that runs at a small fraction of that.

I'll continue "blasting" such "ideas" aslong as the questions I asked above remain unanswered.

Systems capable of running proper RTG-apps/games allready have plenty of GFX options.

Systems lacking such options are only useable for SW that is better served with a pumped up FF.

I was wondering why the siamese rtg was not still developed.
I gathered that as uae got better you could have a faster Amiga on the PC.

How about we go back there. You can get USB graphics cards. Someone write some drivers.

Found a link:

You either have USB in a Z2/3 or even PCI slot, preferably Deneb or Jens' upcoming one -> why not just buy a proper GFX-card ?

You have USB through a clockport -> have fun with that sideshow !


Oh, and still doesn't answer those questions.....

Hint: FPGA.

No closed source except for the development environment.

-> doublehint : get an IndivisionECS and it's "SDK" ;)

Better yet, put a Raspberry Pi running UAE in the Amiga 600 and hook up the Amiga keyboard via a KeyRah. That way it would make no sense at all but have a portable graphics chip (kinda).
