It is not possible for the CPU to determine if a software package is 
performing a floating point calculation by using integer based 
instructions on the CPU. 

A 387 implements a set of floating point instructions a 386 is 
unable to perform these instructions, it is possible for the 386 
to trap references to a floating point instruction and invoke a
routine that emulates the instruction. 

Typically math coprocessors only benefit programs written to work with 
them. There is one exception, if you use MS-Windows and use its math
routines you will experience some benefit. MS-Windows, however, will
not work any faster as it is mostly implemented using integer arithmetic.

It's just nice to prototype the stuff quickly in C, maybe using real
structured data and algorithms (gasp...). When I have the program
running correctly, I'll rewrite bottom-up in assembly until it runs
fast enough. Usually not needed at all, when simple time critical
bit-banging (interrupt handlers and stuff like that) has been in
assembly from the start.

Manage linked lists in external RAM in 8051 assembly? No thanks...

From: <UD156844@NDSUVM1.BITNET>

Greetings!

I'm in the process of buying a 387SX coprocessor,  I haven't yet
decided which brand.  The main reason for buying the chip is to
increase performance for some large Lotus 123 spreadsheets.

My question is will the 387 chip be used for other programs that
don't specifically state any use of the 387 chip.  In reading
an article in a past issue of Computer Shopper they state that
some programs will detect a 387 and use it, otherwise math functions
are normally done via software.  If software does not try to detect
a 387 is the CPU capable of detecting the 387 and passing math
calculations to it?


I would appreciate any answers and comments!

This is the first time I've used USENET, so forgive any mistakes.
        I am very close to buying a 486/33 clone and I have a question
about the Intel chip.  I can save $500 by purchasing the CYRIX 486
motherboard over the Intel one.
        I think the Cyrix chip is 101Mhz and the Intel is 110Mhz
(landmark). I think that the savings are worth the risk to follow a
different path from Intel. As well, being Canadian the savings of $500
translates to 430 beers that I can enjoy in the future.

        CAN SOMEONE PLEASE INFORM ME !!!!!

                        Thanks,

I would say that the on-chip co-processor supplied with the 486 is faster,
since it doesn't have to do expensive off-chip communications between 2
processors.

Subject: Help! Windows DPMI calls to CAS Manager.
Organization: Systems'n'Software
Date: Fri, 9 Oct 92 21:10:12 GMT

Hello,

I need help from your guyes who knows Intel's CAS (Communicating
Applications Specification) Manager.

I am currently working on a Windows program that makes use of Intel's 
CAS Manager that comes with every SatisFAXion board.

CAS Manager is TSR program that provide software services via int2f.

My Windows makes calls to the CAS function via DPMI
simulate-real-mode function (function 300h).

With the following code:

	int  fd;
	int  event;
	long pos;

	event = CASFindFirst(...);
	.
	.
	fd = CASOpenFile(Event, 0, RECEIVE_QUEUE);
	if (fd != -1)
		pos = _llseek(fd, 0, 0);


The value of pos is always -1, if I have a application with a clock,
such as CLOCK.EXE, or HP's DASHBOARD. But it is OK, if I don't have
any clock application running, at least after one or two tries.
(All the CAS C-funcition interface calls used in this program is
coded using DPMI spec, i.e. using the simulate real mode interrupt,
function 300h).

Looks like I am running into some kind of racing condition.

Does any one have experience with this kind of problem before? I need
all the help I need.

Thanks in advance.

Dahai Li

P.S
	I did try to FAX the problem to Intel's CAS-ISD support, but
they seem to be too busy to answer :-(. Why cannot they have voice
line for technical support, like every one else.

Actually, though no one from Intel will admit this, the P5 is suffering
from mechanical instability due to the use of proto-matter. According
to an un-named source in the P5 project, "We didn't have any choice.
We know proto-matter is inherently unstable but it solved several
problems in fab".

So, the same problem that resulted in the destruction of the Genesis
planet rears its ugly head again.

For non-Trekkies: if you don't get this, rent Star Trek II: The Wrath
of Kahn and then you will.

	If the DX2/100 were to use the same "chip doubling" technology
found in the DX2/50 and DX2/60, that would first require support for full
50 MHz I/O to the chip - something supported only on the most expensive
PC architectures. Were that not enough, the heat dissipation problems
already seen in the 50 and 66 MHz DX2's do not bode well for units
running at yet higher speeds.

	Apropos, I recall some technology agreement between Intel and
UniSys, one of whose goals was to work with Intel to tackle the problems
of high-density chips and the associated heat dissipation requirements.

Does anybody know how much heat in watts is generated by thed
i486 cpu.  This is for a heat transfer project I will be 
assigning.  Thanx!

To you have any results from the BAPCO benchmark on the Intel and Cyrix
for comparison? As well can you tell me more about the DX2, when, how
much, how good?

Thanks,
Mike Sullivan

Subject: 8087 /287 /387 Math Coprocessor Bugs?
Date: 15 Oct 92 16:19:25 GMT
Organization: Lehigh University

I have been having trouble with the math coprocessors in my machines not
obeying instructions such as
    FCOMP  (floating point compare and pop stack)  with denormalized floating
point arguments.  The 8087 and 80287 do not set flags correctly, so sorting
fails to work correctly, and the 80387 seems not to pop the stack, so the
program eventually crashes when the 387 signals a stack overflow.
    Question: Is this a known bug?  What are the usual fixes?

BTW, please EMAIL me.
PS: The platforms are various PC clones running TURBOC 2.0 and the debugger
for verification.
    Thanks,
