Single-Chip Linux Computer

Common, even my 4/86 had more memory!? And how do they expect me to compile gnome2 on this? *duh*
Life sucks.
Add some BlueTooth and you might finally have a decent platform to run all those household appliances you've been wanting to network at home. Interesting possibilities at least...
but really, serial ports? parallel ports? i'm not too sure that the scsi is going to win them any points either, but what the hell. they might have well integrated a video controler, an audio controler, and a 9600 baud modem to boot!
Well, I think they target embedded applications and not laptops here. Most embedded applications don't need sound or video capabilities and most engineers love to have serial and parallel I/O, because of their simplicity.
Also from the article..
The overall approach is one suited for connectivity rather than computation, supports data transfer rates of up to 200 Mbit/s (100 Mbit Ethernet full duplex), as well as a wide range of network device applications.
At only 100MIPS, I wouldn't want to use it in a laptop/notebook. Intel, AMD and Transmeta make better chipc for that. This one wouldn't have the computational power.
Great technology, yes. It would make a rockin' embedded system, and could serve up static web pages fast enough to saturate a 100MB pipe. I'll be keeping an eye on it for any future applications I can dream of..
I'd agree on the parallel port complaint, but a lot of stuff out there that won't be going away for years still uses serial ports. I'm not a programmer, but I'd wager that good ol RS232 is a simpler interface to work with than USB and probably more robust over longer runs. I don't think something like this was designed for replacing your desktop.
So many complaints about the "obsolete" hardware - FUCKING DUH! It's a system-on-a-chip, running a common OS that is relatively easy to write software for, using tried-and-true peripheral technology and with enough horsepower to be used in all manner of embedded systems.
Sure, you wouldn't use it in a laptop or even a PDA, but that's not the target -- it can be used anywhere you need a simple PC to do simple tasks, but you don't want the huge and power-hungry old 386 you've got sitting in your closet/warehouse.
The thing's running Linux and is capable of networking for fuck's sake. Use your imagination.

Still,given the feature set and the low power consumption this is a pretty appealing package, but I think even the embedded the applications are somewhat limited.

You couldn't even fit the Windows bootstrap program on this thing, much less the web browser that is integral to the OS.
I want my rights back. I was actually using them when our government stole them after 9/11.
It doesnt want to say what processor it is.
All I can see is that it is a RISC (what isnt) and has 15 x 32bit registers.
Sounds like an ARM ut why dont they say so.

It is available.
The chip itself is $40. The eval board for the ETRAX 100LX is available for $299 as well as a version with bluetooth for $495.
Finally, the order page for both of these is at https://www.axis.com/shop/technology.htm.

It's probably a crazy idea, but at 27x27mm you could fit over 50 of these on an atx PCB. And that's still 2D, stacked you could easily fit a hundred in a litre (though heat may be a problem even with embedded harware like this one).
Of course, compared to desktop computers these tinies have far from impressive specs (see: rants by others), but power isn't necessesarily measured in terms of Mhz/GBs. Power can come in numbers as well. And in that case, price per piece is more important, as well as Watt/instruction and physical size.
Now let's see about bulk prices...

The title is misleading. The device is a multi-chip-module, not a single chip computer. They have packaged a number of chips in a very small package, but it is not a single chip. A MCM will cost more to manufacture than a true single chip computer because it requires a ceramic substrate to be manufactured with very small trace widths connecting the chips that are placed on the substrate.
For a project I worked on at Keio Univ. in Japan, we ordered some of the Axis web cams, which use an older
version of the same chip, as well as some of the developer boards.
The system works as advertised; developing software and
deploying it is very easy, you just do a "make" in the source directory on your host, and it builds the flash rom image, and you download it via ethernet with a single command. You can ftp over to the board to upload binaries or other files, and there's a telnet client.
The only problems I had with the dev board were that it doesn't really have much useful I/O on it.
It has three serial ports and 16 bit parallel port, which can be used as an IDE drive or USB port, but at the time we got the system, you had to kind of roll your own interface. And at the time the drivers for the parallel port weren't
shipping standard so I had to write my own kernel
driver for it.
This is not to say that the designation means much any more... people have discovered how to make the most horrendous instruction sets (read: x86) go fast with only a million (!) extra transistors or so. This CPU doesn't have those, but what matters is that it's fast enough.
Still, it's amusing because half the complexity of the instruction set (and a substantial parcel of the chip) will never be exercised by any compiler. It's there as a sort of homage or shrine to machines from the days when programs were written in assembly language, and machines were marketed on how fancy the instruction set was, regardless of how it slowed the machine down.
The CDC machines were exceptional: Seymour Cray really understood. Also, in the '60s, some people at IBM built the 801, which evolved into the PowerPC. The rest of the industry didn't catch on until the Stanford RISC people made their big splash.
Right so. 2MB should be enough for anybody! ;-)
Red Hat should take notice, but still it's importatn that Red Hat is just as Linux as this tiny system is. And, there is a point in Linux being able to downsize into less than 2MB. Although Desktop Linux is not and does not allow for the same applications as embedded linux, there is a real virtue in sharing the codebase between these two. (Or desktop and webserver, cluster or grid server for that matter.) Although developers may not always agree on the direction the developments should take, together they provide for an open environment that is scaleble, and in escense is very lean. This is something Microsoft can never touch upon with Windows CE/PocketPC/whatever.
That's why I think this one-die embedded linux system is indeed a a-good-thing (tm).
