Once upon a time (Wednesday, March 19, 1997 to be precise), Nick Coons wrote
a letter to Brian McCloud about "Extra Space."...
 [..]
High-level functions which you should never use for anything unless you need
to create a compact routine rather than a fast one.
Anyway, MOVSW is equal to:
         mov       ax,ds:[si]
         add       si,2
         mov       es:[di],ax
         add       di,2
... except for the fact that it doesn't need a register. As you can see, it
moves two bytes from DS:[SI] to ES:[DI] and increments both pointers by 2.
REP MOVSW simply repeats this CX times.
There are a few variations as well, namely MOVSB and MOVSD which move 1 and 4
bytes, respectively.

you might want to consider the possibility that c compilers produce a
lot of unnecessary code unless you're really smart and know how to
optimize your compiler output - whereas the code produced by an
assembler/linker is at least close to being exactly what you put in the
source code (thus the only unnecessary code will be that which you put
in)...

assistant: Yo..
Just a quick point: I have 386 M/B's that DO have VLB. The Opti-495SLC
chipset supports this configuration. It's rare though, and aligned REP MOVSD
instructions are definately faster than REP MOVSW on these systems, but not
by a factor of 2.. it's about a 30% improvement by my observations. Still,
it's well worth having!
With system memory and non-alinged writes, you may find that the cache mostly
absorbs problems there. Of course, in non-cached systems it's very
important.. but hey, this is 1997, not 1987... if you are still coding for
1987 vintage systems....

It has the ability to load and store 64 bit integers with a single
instruction.  (Actually, it can do 80 bits in floating point format, but
those are treated as f.p. numbers and normalized, etc., meaning that
what you later store will not be the same as you loaded.)

Write your reply.

assistant: 486 and above processors always sync i/o instruction execution with
 external bus activity. All previous instructions are completed and
 all writes held pending in the processor's write buffers will be
 completed prior to executing the i/o instruction. Processor write
 buffers are then cleared and program execution delayed until the last
 ready signal of the last bus cycle has been returned.
 The only real reason for NOP's on modern processors is for instruction
 alignment.

This is simply incorrect.  Many cards have modes that use this address
space, particularly when using resolutions above 800x600.  I won't try
to go into every possible time that the address space is used, but it's
definitely used quite frequently, even when there's not MDA around.
You've got your terms confused.  You've given good information about
EMS, but nothing about XMS at all.  The two are _entirely_ different.
