Intel's StrongArm Roadmap
Midvale writes
"PC Week article about the plans Intel has for the next
set of StrongArm chips, .18 micron process, up to 600mHz. These things would be great CPU's for wearable computers."
Its nice to see that this isn't gonna die out.
I'm thinking of something with as nice a keyboard as possible and as low power consumption as possible. A built in modem and ethernet, no floppy or CD, net boot eprom for OS installs and a battery that lasts for ever.
The screen options could include 640x480 black and white which should be fine for vi/mutt/tin/lynx or emacs and save a lot of batteries (and RAM, which saves batteries) or 1024x768 for the X addicts. I don't think the intermediate resolutions are interesting to Linux users. A tuned kernel that does delayed atime updates and doesn't swap unless it has to to keep the hard disk spun down would complete the picture.
Has anyone tried putting their .newsrc and mail folders under CVS to keep them synchronised between a laptop and a stationary?

So far as powerful enough is concerned, expect
the new SA's to actually have FP units (or at
least some of them).
Quoting from www.arm.com
"The ARM10T processor is designed to deliver 400
Dhrystone 2.1 MIPS at 300 MHz, and features an
optional Vector Floating-Point unit capable of
delivering 600 MFLOPS."
As for SMP, that would still be useful, but consider dedicating one SA to the decoding (which
it should be able to do) and another to the rest
of the system (have them running async with respect to one another)
IIRC they have no SMP ability, could still do a beowulf style thing tho.
They are nice chips in general.

Given ARM's repuation for low power chips... The cooling fan in the Netwinder is there for the sake of the HD, and if I am not mistaken, the support chipset puts out more heat than the chip itself -- and thats at 275Mhz

Why would you want to do that? The only reason why Linux should be ported to a handheld is that Linux should get more prestige, as the operating system that runs on more hardware platforms than any other.
Linux (and other unices) are built for computers with disk drives and a keyboard. Most handhelds don't have neither or the hardware support is poor.
Another problem is the lack of virtual memory. If there is none, the usual way of letting applications have control of a large memory area of their own is not efficient.
If anyone is working on an open source operating system for handhelds (that isn't cLinux), mail me. I am interested.

They seem to have forgotten Linux on the list of OSes that support the StrongARM processor (Corel Netwinder). It's nice to see that there will most likely be a new generation of faster netwinder machines.
I have heard that these machines have amazing SMP capabilities. Anyone know anything about this?
It's got some unusual properties -- relatively high tolerance for hard radiation for one. I read the following use in an AMSAT journal a few months back.
:) has been using the same ancient 8bit microcontroller on their satellites for some time now, as most ucontrollers are not suitable to the radiation levels in space. But these days .5 MIPS just doesn't cut it, so they went around looking for a better chip -- and found StrongARM. Their next satellite will have a 133MHz ARM, plenty of CPU power to go around.
:)
It turns out AMSAT (the lunatics who build themselves satellites out of parts they find at KMART
I wonder if they'll run Linux
Yeah, I used to tease my brother when he'd say "millihertz" (meaning megahertz, of course). Now, I'm going to his college graduation this weekend. Hopefully he learned something. ;-)

Program Intellivision!
I would hate to drive near any of you guys. Mixing MP3s in your car? How about a simple Mp3 player that fist in the space my stereo fits now. Grab the dinky little chip out of the Rio and plug it in. I'd just like to be able to take my MP3s on the road with me, before you stick a Beowulf cluster in my trunk, make me a removeable storage media that costs about as much as a blank CD, is rewriteable, and is about the size of a CompactFlash card. The problem with portable MP3 players isnt the processor, it's the storage, 100+ dollars for a 48Mb CompactFlash card. I'll build the in-dash MP3 player if you get me a cheap removeable media.
I'm a loner Dottie, a Rebel.
Well, I have a Netwinder (~280 MHz) and it can
play back MP3s using about 10% CPU under Linux.

Ummmm, the OS plays but a small part in how much CPU overhead is involved in decoding MP3s. It is far more important to have an efficient program than an efficient OS. There will be a point where the OS vs App graphs cross but I doubt that they have yet.

Ok yes digtital did some work with ARM and their CPU but acording to the guys who live upstairs where I worked
(ARM)
they took most of the desighn and then improved it so they could make more money and left digital to their own devices, Digital wail on about itsy but have a look at what
EPOC has done and will do very clever little OS
their are people wandering around with the suits I surpose I dont work their anymore always the way tho
there was mutter about controlers for HD anyone ?
have fun
ARM Ltd (the firm who originally thought of the whole ARM idea and co-developed the StrongARM with DEC) are planning to release the ARM10 core sometime this year. Complete with a FPU. Check out
http://www.arm.com/Pro+Peripherals/Cores/ARM10/
for more details. IMHO it looks better than the planned StrongARMs.
FYI - I knew that.
This message is written under an Acorn Risc PC with a StrongARM processor inside it. I've got an A5000, with an ARM3, in the next room.
When I said 'ARM Ltd designed the whole ARM thing' I meant the people who transferred from Acorn to ARM thus becoming the ARM people.
Given Intel's infamous chip-temperature record, I'm not sure I'd want a 600MHz chip in anything that's going to be on my lap...
I read something a week or two ago that said there would be a version of BeOS running on StrongARM procs. Cool stuff!

I guess it finishes 0.6 clock cycles per second!

The way I have mine configured is to encode direct from a ZX Spectrum tapedrive , and decode on the fly. This is done to ensure the maximum hiss.
Boldy noise reduction circuitry is then utilised to remove this hiss, and provide an 11.1 channel multi aural ( and oral) surround experience.
The subwoofer is currently made of ivory, so this has some issues and may be replaced with other hard tissue. The good thing is that it can be driven by anyone with an HGV licence!
This may go into production sometime in the future. Watch for more news!
I thank you muchly.
These giraffe necks will mesh far more pleasantly than the substances I am currently using, and the occasional whiplash should create a good original beat in the rythym.
I propose that you be given the Nobel prize for music immediately.
I am thinking of creating an MP3 player for my car, based round a handheld.
I am currently working on a parrallel MP3 coder/decoder, and have had some success on my small 4 node Beowulf Cluster.
I dont think that a single StrongARM would be powerful enough, so does anyone know if they will support parrallel processes, and if they will work in parrallel - I have not had the time to do more research on this chip.
Thanks
ARM originally stood for Acorn Risc Machine - it was designed by Acorn. The acronym was changed to mean Advanced Risc Machines when it was spun off as a separate company with Apple and VLSI technology.
..if it too will heat my basement, fry eggs, keep my coffee hot, and make the lights dim every time I start up a process (netscape comes to mind) :-P
