It's absolutely UNREAL the stuff we go through.  We have six truckloads

big IBM 3nnn's and 4nnn's, System 34's, Intel monsters, etc.  Literally

I cannot speak for 1984-85, but I joined Gemini in February 1988 and
was there until BiiN folded.  While Siemens folk (both German and US) were
involved with several different things, the Ada compiler/library
people were all Intel employees during my time.

When BiiN folded, all of us (including the Ada compiler people) who worked
for a certain manager had a photo taken of us under the BiiN logo.  I wrote
down everyone's names so I wouldn't forget.  Many went back with Intel,
some went to Sequent or elsewhere.

The Ada compiler was DoD certified and had reasonably impressive performance.
I've often wondered what became of it (perhaps the compiler manager knows).

You are quite right.  In order to be truely superscalar, the processor must
be able to it own instruction scheduling, like the 960CA/CF processors do.
The 860's, as you mentioned, do not provide this function.

Yes - see the 486 hardware reference manual for details of how

(btw this doesn't just apply to MP systems - the same technique is

This is a question from a friend, so I'm not quite sure I'm phrasing it
correctly. Anyhow, what he is interested is the 0D trap in the IAPX
processors in protected mode. This trap is activated when accessing
protected segments I believe. Now the question is how to set the accesses 
on these segments, i.e. how to make a segment Read-only, Read-write, 
Fetch-allowed etc. Is this information available in the LDT, and how?


Thanks a lot,

One of the very real limitations regards these 32bit OSes that has been

bus. ie. the DMA controllers can only access up to 16MB of physical
memory. OS/2 on [most] ISA machines therefore uses only the bottom 16MB
for process memory and any memory above that for page cache!

I'm one of a two student team doing a design project 
in preparation for graduation with a B.S. in Electrical Engineering.

What we are trying to find is a cross assembler for the i8051 that
will run on a PC or compatible.

The stock stuff that Intel sells is too much for the pocket book
and we were hoping to find a public domain assembler that would
suffice.  We will be using an EPROM burner for the final transfer
to the microcontroller.  If we can just get something that won't
break our bank acct, we'll consider buying it.

I've heard that there are C compilers/assemblers that may also do
the job so any info on those would be appreciated as well.

A reply via email would be better, but I'll check for
info in this newsgroup as well.

It is a bottle neck (in terms of disk storage) when you have Virtual 
memory and not that much physical memory. Local bus is also non standard
and expensive (presently). EISA video would be (currently) a much
cheaper method of obtaining high bandwidth for video. Note that you say
ISA is no real bottleneck and in the same breadth you mention local bus;-).

OS/2 does use memory >16MB. It just uses it differently. In a sense, SCO
(and NT for that matter) use the above 16MB space as a "Process memory
cache" since they would have to copy up/down everytime there is a swap
that involves a page above 16MB. OS/2 uses the space above 16MB as a
simple cache for pages. In both cases, you still have to do copying
to/from the >16MB limit.

Why don't you give intel a go.  I know for sure that they do a 8096 compiler

----------
The 486 is a microprocessor with 32 data paths internally and to memory.
The ISA bus is a 16 bit I/O bus.  The EISA bus is a 32 bit I/O bus which,
in addition to supporting ISA I/O cards, supports a 33 Mbyte/sec burst
mode.  Computer manufacturers build 486 computers with either ISA or EISA
busses.  As has been pointed out, a single user will not notice much
difference between 486 ISA and EISA machines, everything else being equal,
especially if the video controller is on a "local bus".

I was a manager when the 432 was announced.  With commendable
dedication to principle I delegated attending a seminar Intel had
invited us to.  The woman I sent had (like me) come out of CS
research. When she came back, she remarked that the whole set up
was so exciting that she would have jumped at a job if they had been
offering them.

The 432 attacked problems that I had been involved with in
architecture research in the 70s.  While it obviously failed, it
seemed like a signpost to me - silicon was going to become more and
more complex, and be able to solve more and more extreme problems.  Of
course, what has actually happened is that the complexity has gone on
increasing, but (following the earthquake of the introduction of RISC
in most of the industry) has been pretty largely devoted simply to
increasing throughput, ignoring so many of the CS-y ideas that the 432
addressed.
