Disassembling a CPU

Name: Anonymous 2012-09-24 8:44

So how does one reverse engineer the state of art integrated circuits, like the latest Intel CPUs? How costly is the hardware needed for such task?

Very costly.

the fuck are you going to ``reverse engineer''?

You can take the CPU cover off with knife. Then you need some kind of magnifying glass to see individual connections. It is good idea to have a piece of paper and a pen with you, so that you can draw clear images of the circuit routes. It is very hard to memorize all of the connections without taking any notes.

Doubt you can handle manually millions of transistors. And then you've to somehow make sense of them.

Not to mention the difference between the N- and P-layers isn't really visible. Esp when they're ~¼-λ wide…

You need to buff the protective coating down till you can see the circuitry, than examine it with an electron microscope.

Or you could just... you know... read the papers Intel and nVIDIA have been publishing since forever on how every new facet of their chips work.

Then just buy a better magnifying glass you cheapo

if there is a way to write it perfectly, there should be a way to read it.

If it was hard to write, it should be hard to read!

So you're saying you know of a magnifying glass that lets you see sub-¼-λ objects with some kind of clarity?

That's a microscope. I said "magnifying glass", in reply to >>8.

Its magnification elements are primarily glass. Thus, at least one magnifying glass is present, and you must look through it (or them) in order to view a magnified image.

Microscopes and magnifying glasses aren't called by the same words. You'll even find there's a reason for that.

You'll need an electron microscope to see any features of the nm-scale chips.

In which case, the magnification elements are not glass.

Yes, obviously. >>15-17 are about the microscope linked in >>14, nothing to do with viewing a microchip.

That's why you need a pen and a paper.

Don't change these.
