My goodness what was that (German or Japanese text) that went through

I tried that spam message and still can't find the free domain name

Allready Mup21 uses pages and there is a hit for off page access, the
instruction set seems to support it.

Good.
Actually I would like to see a multi-processing module to handle 24 bit
graphics, 3-D, 3-D stereo sound, the before mentioned IO wish list, for
a handheld system (Java, Win-CE, game system). It could be done with
small (simple) resources (a network of F-21, F-32 chips) on module.
Alternatively custom 3D/sound hardware could be included.
We have talked about modules like the PIC-Stick, Dominoes before, I
think it holds a lot of promise.
Is anybody looking at hooking up a intergrated Graphic/3D/memory chip?
The socket-X chip has all the hardware (except sound and ROM) for a
Mup21 system.

I understand they still have slow random access, is there an improvement

So a Mup/F-32 could be attached to each channel, good, how many.

Yes I remember that, last year wasn't it? From my random memory, there
was some guy in Australia couple of years ago that had some technique to
increase the memory through put by 10-100 times, he was announcing that
he was signing uop with one of the competing groups to Ram Bus.

The manufactures are talking about under $25 for the device (one maybe
under $10), one manufacture Colorado Micro-diplay is aiming to release a
consumer display for something like $50-$100 about now (800*600,
colour).
What people don't relise is that they can be used for full sized
displays through projection. By the looks of it, I think, it should be
possible to replace LCD's in notebooks with this system. I have been
thinking of a few techniques to do this. So basically in future it
should be possible to have light handheld computer systems that consume
100Mw of power with SVGA colour display.

Hi guys
I've had an eye on some new stuff that may interest.
- http://www.microdisplay.com
- http://www.microdisplay.com/tech_integrate.html
These are silicon chips with LCD displays matarial incorporated on the
silicon. On the backplane itself can be incorpoarted all supporting
driver electronics for a full SVGA display, and "microprocessors and
memory" a good target for I21, F21. The company is small and probably
eager to find partners. There are others but I believe that this one
has better potential with, I think, their own small Silicon display
foundary.
Incorporated with a reflective mirror type display a tablet computer
could be made.
http://www.socketx.com/
This is Socket-X, a large 303-ball BGA chip socket that goes on
motherboards (Micron at moment) that has all the interfaces for Socket-X
3-D chips. The Rendition Socket-X chip has embedded video memory, Risc
processor and 3D/video circuits. Good technology for F/I 21 to fit on
or just as a graphics processor for Mup21 ;).
VMLABS have designed a new videogame platform, Project X, for
incorporation into DVD plays, replacing the existing chipset at simular
cost. This would enable them to get a wider user base for little
effort, something that would have been possible years ago with Forth
Chips. http://www.vmlabs.com
That's all I can rember I've had another lecturer in and out of here
talking to me while I've been trying to rember things, and this software
has been crashing so I forgot the rest of the stuff.
Thanks
Wayne.
