How do processors work?

Sun Mar 29, 2015 7:40 pm

In one sentence hehe.

I just liked to get a collection of peoples thoughts in one sentence.

I'm going to borrow my sentence from one of my favourite SF writers.

The sun in midsummer always rises exactly opposite where the midsummer sets. Using these two points as alignments and various other observations its possible to compute the positions of significant astronomical bodies at precise times throughout the year by placing really really really big rocks in specific positions around in a big circle and watching when sunlight or shadow strikes them. Allegedly.

My corollary to that:
It's just ones and zeroes that we've got to put back in the right order.

No, "rearrange" implies that the total number of ones and the total number of zeros do not change.

I must have entered the crazy part of the internet again?

I think it is an impossible question to answer, making too many assumptions, dependent upon a shared vocabulary, noumenals, context, and axioms of system.

I am not even sure I know what you mean by 'processor'

Layers of abstraction maybe important, mapping from one input to another output, I am starting to feel I am just placing characters sequentially onto a screen that really make no sense.

Is a process something that involves change? I assume change requires time? some sort of representation of scale, a certain number of dimensions, something maybe we could call it an operand that can be changed, the process or operation converting the operand from its initial state into some other state in a constant and repeatable way based upon all inputs to the system?

In that sense maybe everything is a processor, so I really have no idea how everything works.

How it all works is implementation dependent, how do we represent the input and output, how do we define the mapping based on those inputs, etc. its all based on so many layers of simplicity that it become too complex to easily explain.

I don't really know.

How do processors work?
That should be shortened to:
Do processors work?
And the answer is:

They don't

They're a lot of NAND gates interconnected so that putting something into one or more of the inputs makes something else pop out of one or more of the outputs.
You, the user, have to assign meaning to the input and the output, and then decide whether any connection between those two is meaningful, and if so, if it's true.

In other words, to be able to ask a question, you need to know most of the answer (to quote someone whose name I've forgotten.)

As a ham radio operator, I know that you are right. We hams know that
all electronic equipment is powered by blue smoke. To prove this, all you
have to do is to let all the blue smoke out and you'll see that it no longer

In one sentence? In one web page would be a challenge. If you really want to understand it read a book (or several).

Microprocessors switch binary patterns in memory (or i/o) into arithmetic and logic circuits as data and/or control, writing results back to memory (or i/o) to produce 'intelligent' system behaviour.

I sometimes like it when interesting thoughts occur, I remember a few years back there was some competition to create 'quines' in javascript the idea being to create a 'program' that can fully describe itself. Which made me wonder if a human could ever describe themself, but then I realised description is not necessarily the same as understanding, I assume understanding of a system means that prediction of outcome and modification of the system could be made. I came to the conclusion I could never understand myself in the present, but maybe I would realise later wtf I was doing previously if I spent sufficient time analysing the situation later, but there was never any chance of knowing anything when other people became involved.

Then I realised I was thinking too much when I could be doing something useful instead. :lol:
