CPUs - How they work?

[Freezee]

Hi!

I'm very interested into how processors are working, I already saw things about how they're adding numbers with logic gates, but I know they are doing way more things than that, so I was wondering: where could I find a good place where everything is explained about everything in a processor?

I wanna know how each component works, what they're doing, what's the difference between this processor and that one (by looking inside of it), and on...

Do someone know a good place to learn all that kind of stuff?

Wikipedia?

I don't think Wikipedia is explaining all logic circuits in depth ^^

Google does tho

I don't think we can explain all logic circuits in depth on a forum either

but it's basically a bunch of logical elements hooked up together to form complex units and then the electricity flows into one end and flows out the other end - depending on which end it flowed out of you get different colors of pixel on your monitor

That's an oversimplification of what's occurring. During 3D games for example, the GPU is actually working with 3D models, but has to turn that into something that a monitor can output, which is 2D.

You started off good, but... That isn't how it works.

 

The CPU uses logic gates to perform mathematical instructions. The GPU (All computers have a GPU, just not all have discrete ones) takes this information and uses even more logic gates to turn this into a set of instructions or an analogue signal which your monitor can understand, and you see as a complete image or text.

 

Think about how many calculations are going on in your CPU and GPU to render a 3D game. Everything from lighting, textures, movement, shapes.
