OT: Good introduction to CPU/Memory terms

| When I read about registers, pages in memory, offsets, all that, my
head swings because I don't understand a word. Is there some nice
tutorial that can teach that stuff?

Mostly you don't need to know it anyway, not to write C programs.

I don't know of any *nice* ones, in the warm fluffy sense. But "The Art of
Assembly Language" is legally available online for free. It may or may not
be what you're looking for.

As Richard has mentioned, the 'Art of Assembly Langauge' available at
the URL below does an admirable job of introducing x86, 32 bit,
application oriented assembly programming. It only deals superficially
with Operating System related aspects like Paging etc.
<http://webster.cs.ucr.edu/>
Just Google for the terms that confuse you. Many links have excellent
information. However without some knowledge of Mathematics and Physics,
you're bound to be frustrated.

No knowledge of physics is required to understand the concepts he mentioned,
and no more knowledge of mathematics is required than what you learn in
elementary school. The smidgeons of discrete mathematics you'll need that
you probably haven't had in elementary school (boolean algebra, mostly) are
easy to pick up.
To understand the entirety of processor design does require a good deal of
both, but that's probably not what he's asking.

It is definitely an interesting read, I've not read it all yet. But
it's specifically targeted at x86. I want something broader; I was
always interested in console emulators (8-16 bit). I've found some
tech docs and I've got the source code for some emulators so i want
to see how they work, but the technical docs describing the system
talk about registers, ports, pages, memory, addressing modes as if
they're well-understood terms. And of course we're not talking about
x86 there.
So I was basically looking for an intro to that stuff that will make
it easier to move from CPU to CPU.

What is this? Is it a "search engine" or something? I keep hearing
about them. They must be catching on. I'm too reluctant to use one
yet though.

google for 8051 programmers manual, it will give you a good introduction
to a venerable and still popular 8 bit micro.

You may only act like it's your first day on the internet,
for one day.
After that, you turn into a troll.

Since you know it is OT, why not ask somewhere it is topical instead?

Then completely forget about *all* of that stuff and just write standard
C. Or standard Java. Or standard any language that is available across a
wide enough range of systems.

Well, the systems I'm interested in didn't have C or Java. They were
programmed in assembly only.
I asked here because it's a group frequented by programmers who
mostly know lots about low-level programming. If you don't like OT
posts you're free to ignore them.

Yes. It's called "college". A tutorial is just about all it is these
days.

We're also free to complain that they're off-topic. We don't /want/
to have to ignore off-topic posts; we'd prefer that they weren't
made or, if made in error, that the poster accepts redirection.
At some point the effort of ignoring OT posts - no, it /isn't/
free - outweighs the value of the group. We'd prefer that didn't
happen.
Acknowledging that you did wrong doesn't make it right.

No, it was a bomb. Jokes are funny.
