Hi all
I'v got an idea for program that woud change history of computers.
Coud it bee posible to make a program that woud act like a procesor? So =
you coud play Qake 3 on 486 for example.
Iz is not necesary that the program woud bee made in EU.
You think that I am crazy. I am yust asking.
Lep Pozdrav
Jan

2. Re: Virtual procesor
This is what a virtual machine is more or less. Java's is the most =
famous, but there have been a couple virtual machines designed in Euphoria =
as well.
A virtual machine has the advantage of being able to write programs that =
are 100% portable without modification to any platform that runs the VM =
(virtual machine). It also allows for functional enhancements over what =
the host processor may be capable of (byte codes for string math, for =
example).
The main disadvantage of VMs is their speed. A host processor must spend =
several more cycles processing an instruction through the VM than if it =
handled the same instruction directly. While it's theoretically possible =
to write a VM that would allow you to play MMX games on a 486 or other =
platform, the slowness of the VM in performing each MMX instruction on =
such a platform would make it not worth playing.

You mean a virtual machine? Been done, many times (that's how JAVA
works) :)
You can't make your computer faster by using a virtual machine, the
virtual machine still has to run on the host processor, so sorry, your
just gonna have to get a better computer to play quake 3 ;)

Uh...
I proposed to code that a couple of days ago, IF
people showed support...
No one did, so...
But yeah it's possible,
Q3 would run like a snail on a 486, though...
But it's doable...

I recall that, in certain circumstances, the virtual machine code actually
runs faster than native. Typically, there's some clever optimizer that's
looking at the instruction blocks, and figuring out optimal branching and
other stuff that's beyond my comprehension.

6. Re: Virtual procesor
Hmmm..
Nah...
That's impossible...
Even with the best of optimisations, it will always
run slower...
Especially in Euphoria...

Take a look at HP's Dynamo:
The short version:
"Dynamo creates straight line code from what may
have been intricate control flow, and Dynamo can
optimize fragments across boundaries that a static
compiler cannot."

8. Re: Virtual procesor
Hi all
I think you miss understanded me. I was traying to ask you if it is posible
to write a program that woud bee like a procesor so you coud swich off the
real procesor and use the virtual one.
Lep Pozdrav

I've heard the same thing - but I also seem to recall that this can only
happen in cases where you're 'emulating' a slow processor on a fast one,
which is just the opposite of what the person who started this thread wants
to do.

Well, one thing is for sure...
If what David says was true,
then Intel is in the wrong bussiness and should be
coding virtual Pentium IV's that run on 486s instead
of spending a decade engineering faster chips...
See what I mean?
You can't just do post-link optimisations on machine
code, interpret it, and expect it to run anywhere near
the speed of non-interpreted unoptimised code being
executed by the processor.
A virtual machine is fun for many things.
For one, imagine a 'pcall()' for Euphoria, wich
interprets each machine code.
That way, with future support for non-intel platforms,
your machine code still works.
And that day might be here sooner than you expect...
