Subject: How the coprosessor in the i486 is working ?
Keywords: i486, coprocessor
Organization: Rogaland University Centre
Date: Wed, 27 Jan 1993 14:51:07 GMT

I'm working with a program at may PC at the Rogaland University Center in 
Stavanger, subbandcoding. The question is: Can the coprosessor work alone, a 
sort of parallell processing, or will the main processor stop and wait until 
the co-processor is finished ? 

I have to know this because I'm going to optimalize the program so it will 
go much faster then the JPEG standard !!!

If i program in assembly direct in the C-program source, will it go much 
faster ? If I program the coprocessor direct (f_xxx ), will that go much 
faster than else ???

Please Answer Me

There are a couple of new 486 specific instructions, but nothing that 
can't be implemented with 2 or more 386 instructions.  The intent is to 
make it possible to update semaphores in multi-programming systems on the 486
in one uninterruptable instruction.

You're joking here, right? Or did you mean the Alpha chip instead of

Subject: i860XP pin functions
Date: 26 Jan 93 15:37:04 GMT
Organization: Advanced Micro Devices, Austin TX.

1] CACHE# 
The manual describes this pin as indicating the processor's
intention to cache the data on cacheable reads and code fetches.
How does the external core logic use this information? Unlike
PCD, this pin indicates the cacheability on a line-by-line
basis. Does the CACHE# pin become useful in the case where
paging is disabled, or for a cycle that is not paged? But
even in this case, the internal cacheability of the line is 
disabled since PCD=1. 

2] EWBE#
The value on this pin during reset determines the ordering
mode used. The i860XP manual mentions that in systems that do 
not have external write-buffers, this pin can be tied to Vss
for strong ordering, and to Vcc for weak ordering. This would
mean that this pin remains always asserted for strong ordering,
in systems not using external write-buffers. Is the EWBE# pin,
ignored in this case?

Any clarifications?

Hello everyone,
    I am in need of assistance.  I am an IBM user and have had little 
experience with Macs.  I am on several local BBS's where a lot, I mean
A LOT of Mac and IBM bashing goes on.  Now, of course I stick up for IBM, and
it's also amusing to watch the other users get irritated and say stupid things
(the average user age on the particular board to which I am referring is 14), 
but I am as ignorant about Macs as they are about IBM.  The keep referring to
these "speed tests" and "benchmarks", but no one can seem to remember who
performed them or under what conditions, etc.  These users have also requested
that I upload specs on Intel microprocessors (which is what I have been doing
for months now) so that they can compare them to Motorolla processors.  What
I really would like is an UNBIASED comparison of Mac and IBM, as well as Intel
and Motorolla.  In addition, I would like to be referred to a GOOD technical 
reference manual for Macs in my everlasting pursuit of knowlege.  I'm not asking
for anyone to tell me how good the Macs are or how crappy the IBM's are because
I like my IBM and I'm not going to buy a Mac, I merely wish to become more
educated on the subject so that I don't sound as ignorant as the afore mentioned
Mac using "IBM experts".  For example, I have a very good book called "Upgrading
and Repairing PC's" published by QUE (I like QUE books very much and have
several others).  If any of you are familiar with this book, I am looking for 
the same type of thing with regard to a Mac.  Thanks for any help you can
provide.

The i750 is being promoted by Intel as a multimedia chipset - real time
video, MPEG decompression, video effects, etc.  Does the i860 have the
wherewithall to compete with the i750?  The bus is wider, it runs faster,
but does the lack of the i750's microcode ops and the bus latency accessing
the VRAM lower the real time performance such that it cannot perform the
same functions as the i750 (as well as its strongpoints - 3D rendering,
Phong shading, blits, etc)?

Thanks,

Hi!

(Hope this is not a FAQ or a stupid one):

What will happen to the upper 16 bit content of the registers EAX,EBX,...EBP,ESP
etc. when using 16 bit instructions?
Example:
MOV EAX HFFFFFFFF
Add ax,1
EAX=????????????

My 486DX seams to leave the upper 16 bits unchanged but the 
real question is: is this a documented (where) feature? What about
all these dozens of 386 and 486 clones, and the 486 part of the 
Pentium??

If the upper bits are unchanged, this would give you a second 
bank of 16 bit registers (switching between the "banks" with ROL E**,16). 

However, if for example XOR ax,ax is simply treated as XOR EAX,EAX
by the processor and the 16 upper bits are changed, this could lead
to *serious* problems when using DOS programs compiled with the -3 
option of BORLAND C++ 3.1: BC++3.11 code uses 32 bit registers to
handle "long int"s. MS-DOS interrupts use (and save) only the 
16-bit registers (the lower 16 bits of E**) 

I tried to look this up in various handbooks for assembly programming,
but none had the answer. I couldn`t find anything Intel-official on this, 
either.

Could someone please give me a hint or pointer to the right 
Intel-docu??

Please reply via e-mail.
Thanx in advance.

products)?

new board right from the beginning (64 bit VL on ISA/EISA, or other)?

ps one vendor today was trying to tell me not to wait for the Pentium
since it was only advantagious for those doing major math
calculations.  I figure even if not taxed by my graphic and video
(production)  work, it will still scream by the 486.  

pps.  question two is especially important to me since my video
production hardware is on ISA/Eisa boards.

Subject: 82780 on the 486 local bus?
Organization: Telecom Australia, TNE Computer Support Services

The 82780 is an Intel support chip that provides high speed, 8 channel DMA,
20 interrupt lines, internal timers, DRAM refresh timing, and a set of steak
knives.  I would prefer to use it on a project based around a 486 rather
than Intels 82350 chipset because I don't need (want) all the extras the
chipset comes with.  However, the data sheet for the 82780 says that it's
optimized for the 386 bus, and I can't determine whether it will function
on the 486 bus.  The NA# input to the 82780 I can work around, but are the
timings on the 486 bus so different from the 386 that it precludes the use
of the 82780?  Any replies or pointers to applications notes would be
appreciated.

G'Day,
	We've got a little problem in that we require an extremely fast
floating point accelerator for a PC based system, but one that doesn't
cost the earth. I've seen i860 plug in cards, but here in Australia,
these retail somewhere around the $8-15k range, more than we can afford.
I seem to recall that a company named HAUPPAGE (if I remember correctly)
used to sell a 486 motherboard with an i860 built into it. Further, I'm
sure I saw a PC on sale in the UK with this board for around 3k pounds
sterling. So does anyone have a contact for an Australian supplier (or
failing this, the US suuplier) of these motherboards, or any comments
generally about them ?

An EPS file must contain at least the following two lines at the beginning
of the file:

%!Adobe-1.0 EPSF-1.0
%%BoundingBox: <xmin> <ymin> <xmax> <ymax>

The minimum and maximum values must be given in point (1/72"), assuming

For better performance some additional "%%..." comments are required.
If above given lines are no good to import your EPS into Word, mail me.
