  OFFICE MEMO          Defining Embedded Systems              Date:15/04/92

Hi everybody,

	As we talk more and more about embedded/real-time systems I think it is good
to propose a sort of definition. So please find below some caracteristics of
embedded systems I have been collecting. Feel free to comment and/or add
anything to it.



* The difference between an embedded system and a free standing computer
largely depends on how users perceive their interaction with it. If users
believe they are working with a computer, it's a computer. If users see
themselves as interacting with something else (a fax machine, an airplane or a
printer for instance), it's an embedded system.

* Embedded systems are part of a larger system whose main purpose is not
computing. There is a strong interaction with the rest of the system which
normally means direct physical and electrical connection.

* Embedded systems have absolute performance requirements. The system must
satisfy all requirements in absolute terms: if the requirements are not
satisfied, the system will not work. The most critical requirements are
generally specified in terms of time or temporal reactions, so, the terms
"real-time" and "embedded" are very closely related.

* Embedded systems have a specific purpose. Although most embedded systems are
a combination of hardware and software which allows a certain flexibility, the
purpose of the embedded system does not change during its lifetime. One
consequence is that operators do not generally load or change the software,
this being regarded as a maintenance operation.


Thanks in advance.

  OFFICE MEMO          OSI/MMS Feedback required              Date:15/04/92


	As you might know, MARBEN is a french company developping OSI related
products. MARBEN did port part of their OSI software to VxWorks.

1-WHAT HAS BEEN DONE:

Today MARBEN/OSI protocol stack runs a VxWorks 68k based target up to the
transport layer (TP4 interface).

The Data Link level which has been tested is 802.3 (ethernet).
They tested it actually over on board ethernet link available on a typical VME
single board computer.

They also did some evaluation on porting MMS client on VxWorks.

WARNING: These ports must not be considered as off the shelf products.


2-MMS (Manufacturing Message Specification):

To be simple and quick MMS is a standard protocol standardized by OSI. The aim
of MMS is to inter-connect any kind of factory equipments (e.g: robots, PLCs,
numeric machine tools ...) and to have them communicate easily and efficiently.

The biggest part of MMS is the server side. MMS server services are subdivided
into several classes such as Communication,Equipment, Tasks, Domains,
Variables, Semaphores, Events and so forth.

As some equipments and applications don't have to support all MMS services, big
customers or OEMs have defined MMS Profiles. A MMS profile is actually a subset
of available MMS services. As an example the EDF Profile seems to be a
reference in France.

A MMS server software package can't be fully developped hardware independent.
That means MARBEN would provide a MMS server environment package that allows
customers to interface with their specific hardware equipments.


3-FEEDBACK NEEDED:

In order for MARBEN to port MMS server (or at least part of it) MARBEN and WRS
need to know whether or not it makes sense. Is there a real market and how big
is it? What MMS services are required? Does it make sense to productize
something? Idea of Pricing eventually?

Whenever you have a request regarding OSI and MMS feel free to let us know.
Although there is no real product for time being MARBEN is able to provide high
level consulting services around potential OSI/MMS implementation with VxWorks.

We need inputs from anyone and especially from the field (WRS ,OEMs and 
Partners Sales and FAEs for instance).

Send comments and inputs to me and thanks in advance for your contribution.

Date: 8 Apr 92 18:40:40 GMT
Article-I.D.: petunia.1992Apr8.184040.13682
Organization: Applied Research and Development, San Luis Obispo CA

I am a student researcher here at Cal Poly doing work for California Dept. of
Transportation (CAL TRANS).  We (my research group) have been using OS/9 for
our VME (147A) as a platform for developing real-time data collecting software.
Recently, we've heard of the operating system, VXWORKS.  Someone suggested that
it would be a good replacement for OS/9 since we have encountered some problems
with it.  However, it will take a lot of work to port over code developed on
another operating system (especially real-time software).  I was hoping that
somebody out there has had a similar experience and would care to share his/her
ideas and comment on VXWORKS as a software development platform.  Of course, I
would welcome any opinions, suggestions, etc.

I know very little about this operating system; therefore, I would also
appreciate the names of any books (and their author) and references that can
help me.

I am most interested in these areas:
1. TCP/IP, and RPC support (our VME will be communicating with a bunch of Suns).
2. Reliability; our real-time software must not fail because of OS bugs.
3. Serial device communications. (modems & serial connected workstations).
4. Good technical support.
5. A UNIX-like interface would be nice.

Thanks in advance.

The man page for the VxWorks function etherAddrResolve() (as well as
the page for etherOutput) includes the following reference via code
fragment:

      struct ifnet *pIf;
      pIf = ifunit ("ln0");

I can't find a macro definition or function prototype for ifunit()
anywhere in the Vx stuff.  Structure "ifnet" includes a member "short
if_unit", which doesn't look pertinent.

I can infer that ifunit() can be properly prototyped as:
	"struct ifnet *ifunit( char *)" 

However, I'd appreciate confirmation...

Thanks in advance, Bob

	I am trying to setup a scsi disk on two different vme systems
running VxWorks.  The system consists of a MV167 motorola board (68040) and
and 4 SkyBolt AP's (i860's), a harddisk connected using the scsi port
on the 712M transition module which connects to the MV167 via the P2 adapter
board.  The boot files reside on a Sun Sparcstation.  Both systems
are using the same file.  I have done this in the past, the only difference is
I added the #define INCLUDE_SCSI to the target config.h file.

	Both setups identical.

	The first fails right after it loads the kernel with

	Starting at 0x100...

	The second one boots fine!
		The difference is the type of vme chassis the first one
uses a Force Target 32 chassis and the second uses a ruggedized chassis
by Cyberchron, I have no reason to think either chassis is faulty.
	
	The main problem I have is how do I set up the scsi? I do have
the VxWorks Technical Notes "Using SCSI devices with VxWorks 5.x"
	
	I have run out of ideas, any suggestions?

Well, yes, but who's a user?  I'll offer two counter definitions.

(1) Embedded systems are something that embedded systems kinds of
people do.

In the flight simulation business, there are people who need to be concerned
with exactly the same kinds of things that concern people who design black
boxes, controllers, and so on.  They need to know about interrupts, hard time
deadlines, scheduling, resource locking, device control, and so on.

To the guy who's gotta know that stuff, a flight simulator is an
embedded system.  To the other engineers a flight simulator *shouldn't* be
an embedded system.

(2) Embedded systems are systems that are actually embedded in something.

The Air Force a while back defined "Embedded Training" as something that
was "built into or added onto" a system (aircraft, etc.) that provided
training capability.  For example, an embedded training system in
a submarine would let the sonarman turn a switch and his radar would start
showing bad guys.

By definition (2) an embedded system probably ought to be "built into or
[designed to be] added onto" something.

I *love* religious discussions like this, and it really just depends on
where you start drawing your boundaries.  I prefer to start at the extremes
(to find out if they really are extremes) rather than at the middle.

Best to you,

Advanced Digital Corporation used to make several S100 products and 
still sell a hard disk controller.  Their phone number is 714-891-4004.
I have not purchased anything from them except for a manual for the 
S100 system that my department received as a donation.  So I cannot
comment on the quality or reliability of their product.  But the cover 
of the manual I bought for the Super Quad S100 computer states that
this was the first S100 computer!  (This is a Z80 computer; I have no 
idea if your 10 MHz CPU is compatible.)

Don Maslin, in an earlier post this year also provided me with the 
following information, which I have yet to follow up, since with his 
help I found Advanced Digital(Thanks!):

"There are, I think, a few outfits yet making S-100 cards -  I'm not sure
about whole computers.  Viasyn in the San Francisco Bay area is one you
might check on, initially.  Query 'cmcewen@gnat.rent.com' for possible
others."

Ah, a question that appears about once every 4 months or so.  Here's
the info I re-post for those TRS-80 fans:

	This is the only info I have on commercial TRS-80 emulators.  I
	found it in comp.sys.tandy:

	Subject: Re: Tandy emulator for IBM-PC

	I received a letter from the original requestor stating that he did
	indeed want a Model I/III/4 emulator.

	The only emulators I know that exist right now are commercial and
	available from Hypersoft in the U.S.  Here are the descriptions:

	PC-3 is a Model III emulator for PC-compatibles with at least 384K
	of memory.  It requires the MODELA/III file from a TRSDOS 6.2 disk,
	and you must own your own Model III DOS.  It comes with a program to
	transfer diskettes from TRS-80 format to MS-DOS format, but
	depending on the type of your PC's drives, you may need access to a
	working TRS-80.  The price (including one free upgrade) is
	US$109.95, although PC-4 and PCXZ owners can get a better price.

	PC-4 is a Model 4 emulator also for PC-compatibles with at least
	384K of memory.  The advertisement I'm taking this from implies that
	you don't need to purchase a separate DOS for it.  The price is
	US$74.95 alone, but it does not include a program to transfer files
	from TRS-80 diskettes.  They have special prices for transfer
	programs if you buy them in addition to PC-4.

	For more information, write or call Hypersoft at:

runs under CP/M that can read DOS disks (360KB of course).

Please respond via e-mail to:
