Overview of real-time embedded systems for non-embedded developers

Any links to overview/principles of real-time embedded systems for
*non-embedded developers*?

Ethernet, RS232 and other, Modems, Cards, Ports (Serial, Parallel,
etc).

Thanks in advance,

Using your requested topics for feeding google "real-time embedded links"
http://www.google.com/search?q=real-time+embedded+links

results in a lot of useful hyperlinks with link collections
One of my favorites : http://www.eg3.com/

Thanks.
But what I need is to find some specific material: *principles* of
real-time embedded systems for *non-embedded developers* to get
starting.

No idea what the difference is. But anyway, if you want to get experienced
with this topics, you should read all what you can get.

I think you are asking the wrong question.  You are confusing two
different concepts, although they do often occur in the same systems.

There are embedded systems, and there are real-time systems, with
varying degrees of real-time "hardness".  You can certainly have
either without the other although, as I said above, many embedded
systems also have hard real-time requirements.

Now you have added a third topic, one that is not necessarily related
to either of the other two.  You are talking about hardware devices
that require some sort of specific software, commonly called device
drivers, to control.

Hardware devices and drivers exist in all computer systems, whether or
not they are embedded and/or have real-time requirements.  Just for
example, every single operating system that you can run on a 32-bit
x86 PC, which includes MS-DOS, any version of Windows, Linux, BSD,
Solaris, QNX, VxWorks, and the upcoming Mac OSX for x86, have to
provide device drivers for the keyboard, mouse, hard disks, floppy
disks, CD and DVD drives, MODEMs, real time clock, system timer,
interrupt controller, DMA controller, serial and parallel ports, and
more.

A few of these operating systems, particularly Solaris, QNX, and
VxWorks, have specific properties to allow hard real-time requirements
to be met.  Most of the others do not.  Yes each one of those systems
needs device drivers for each of the hardware devices I mentioned
above, and the driver for each device is different for each OS.

> Thanks in advance,

As others have said, the topics of "embedded systems", "real-time
systems", and "device drivers" are very broad.  I'd suggest that you
might do well to start by picking one of those topics to start
investigating.

Thank you very much. Your (conceptual) answer was very useful.

Starting out from http://www.eg3.com/ I found this: 
http://people.mech.kuleuven.be/~bruyninc/rthowto/
Perhaps you could use it.

Hi Folks,
   was reading the archives for just this kind of information ( the
non-embedded developer getting into embedded space [and real time this
time]).
I am a Mechanical Engineer into programming (C programming for
networking device) for quite some time now. I have recently been
assigned to a project which requires *Embedded Knowledge* according to
the Lead.
Can any one tell me the nuances of Embedded Device Progg vs. Embedded
Application Progg.
   I have read the device specifications and have understood the memory
map.
Any other pointers will be greatful.

Regards,
_Ajai.Jose_

I think embedded systems is very vast domain.
You first identoify in which area you want to work..like embedded
application programming,
firmware development, embedded middleware development, driver
development etc...
You can refer following few books :

Embedded Systems Building blocks by Jean Labrosse
The art of embedded system design by jack ganssle
The firmware handbook by jack ganssle
visit few sites like 
embedded.com
http://www.ganssle.com/
