newbie question ARM and windows

Started by sebastian June 28, 2004
hi,

i just saw that the new HP49G has an ARM running at 60MHz, and it got
me thinking that my first computer was a 40MHz 386DX with 4MB of RAM
and i remember i could run windows 3.1 on it. Does it means that i
could run windows on an ARM running at 60MHz (not on the calculator of
course)
could i build a computer with an ARM? (i think Acorn computers were
based on ARM) but i'd like to know if it'd be possible to build it
from scratch
thanks

When you say you want to build one from scratch, what do you actually mean? Do you mean: 1. you want to start with a chip like the lpc2000 series processor, etch your own 2 layer board(minimum here), design the peripherals around that and finally make an operating system from scatch for it, or 2. start with a minimal board with a processor on it(like the ones from olimex) and then build peripherals around it, and then uses say a OS like uClinux and recompile it for your needs, or 3. start with a single board computer heavy in peripherals, eg. CF interface , lcd interface, keypad interface, and much more. Maybe even have it pre- installed with some sort of OS, or lastly 4. build a computer, read as "put a computer together" usually a wintel box or similar. Personally, I'm working from 2. Its not that hard, you just need to be decisive in what you want. Cos, you can't have everything on such small devices. P.S.

Not for the typical meanings of the terms "run" and "Windows" you can't. You can run specialized versions of a system superficially similar to, but internally quite unlike regular Windows, on ARM CPUs in the 200+ MHz range. The resulting system is called a "Pocket PC" or "Windows Smartphone", depending on what version of Windows CE is on it, and whether it has a mobile phone built into it. The major problem in doing this yourself would be that individual developer licences for Windows CE essentially don't exist.

You may have to stretch the meaning of "possible" a bit, but: yes, it's possible. -- Hans-Bernhard Broeker (broeker@physik.rwth-aachen.de) Even if all the snow were burnt, ashes would remain.
