What means embedded ??

Hmm…that opens a whole philosophical can of worms doesn’t it? Are we
“general purpose computing devices” or “special purpose that the user can’t
monkey around with”?

cheers,

How about “anything that isn’t a desktop, server, or mainframe.”

I don’t think my wife would like to be called an embedded system.

lol. Don’t we speak about smth with processor inside? I don’t believe such thing is inside your
wife.

Where is that cafe conference when you need it?

I try to keep thing simple: something that doesn’t run
based on QNX6.1 automatic installation.

Second criteria: no HD.

I would have said No Hard Drive as the first criteria.

Okay…I’ll stop now. :wink: Looks like they made a cafe newsgroup just now
anyway.

OK. Now that I’ve read a bunch of other posts I’ll modify that to something

that doesn’t boot from a hard disk, i.e. ROM or Flash.

A device is an embedded device if it is ‘embedded’ into a superior
device … like a motor management system of a car.

Such a device doesn’t process generalpurpose applications which need
interaction via generalpurpose
input/output devices like a keyboard or GUI device.

A PDA is a small device … a settop box is an embedded device because
it doen’t allow the usage of generalpurpose applications and it works
only in the context of a TV [lously embedded :slight_smile: ]

An embedded system is a system which can’t be used location independent
… that means it needs a specific environment for its operation.

You can move a PDA or a desktop PC from one location to an other … it
simple works again.

This is e.g. not possible with a SoftPLC, a settop box or a multimedia
device of a car.

IMHO … QNX is also well suited for small devices and not only
for embedded devices (environment dependent devices).

Armin, you have a gift with words. I think that you have the best
definition so far. We should line up all the definitions and have
everyone vote. Maybe we could make it a Slashdot poll…:wink:

Cheers,

If you build an embedded system (what ever that means) but are
having a memory lead in devb-eide. My understanding is this conference
is not meant to discuss such an issue.

IMO this conference is for things like, IPL, custom images, custom startup,
BSP. Compact Flash, XIP, compression, QNX6/Photon on a floppy

I agree with Mario here.


Funny isn’t it somebody ask for a embedded conference, QNX created one
( awesome ). Now we don’t know what to make of it, lol!

Agree once again! :slight_smile: I just happened to come across this, like just
about every thing related to QNX. What a trip!

Bests…

How can we define Embedded systems ???

I like the following definitions:

EMBEDDED SYSTEMS are those used to control specialized hardware in which
the computer system is installed. A software system that is completely
encapsulated by the hardware that it controls. For example the the
inertial measurement unit (IMU) in the space shuttle or a cell phone.

ORGANIC SYSTEMS are completely (not highly dependent) independent of the
hardware on which they run.

LOOSELY COUPLED or SEMI-DETACHED systems are systems that can run on
different hardware but with modification of specific modules.

And by the way is there anybody who knows about an A/D-D/A board with
qnx-drivers?

I think an embedded system is a system that is not visible to the user.
(Use your favorite description of “system” :slight_smile:

Embedded software is basically the same; the user does not know what
software
is in the black box, cannot see, edit, change it. (Compare this with your
desktop,
and see the big difference.)

In some cases, of course, an embedded system is connected with a user
interface
to make it controllable or even configurable.

Leon Woestenberg.

No but it runs nicely on an iPaq…:wink:

I suggested it-thank you to whoever implemented it!

Pity I only by accident discover it now! (A chance remark by Bill in .advocacy).
Was this not worth a post in .news?

Mario-I agree with your list of possible topics to cover in this embedded newsgroup.
Virtually all the other NGs are consumed by general installation problems!

My car has an embedded computer and it moves all over the place. It vists a
lot more locations than my PC.
J/K :slight_smile: I know what you mean. When people ask me what and embedded computer
is I tell them “it’s a computer in something that’s not a computer”. Of
course following my twisted logic from above, then my PC is embedded because
it’s in my house.

Embedded systems is actually exactly what the name says:
Its a system where the basic components is all embedded, whether on a custom
chip or a pcboard, so in other words a system where you cant upgrade the
memory or processor generally is considered an embedded system.
Usually the only thing upgradable in an embedded system is the firmware.
