Discussion Computer processors are ANALOGUE. Analogue modelling EXISTS in software!

[DJJC]

There is an INDIGNATION happening everyone. Computer processors are ANALOGUE that behave digitally. Analogue circuitry in digital form on computers, is available TODAY. Korg, Roland, Universal Audio, Arturia all do digital, software analogue modelling. IMAGINE WHAT COULD BE ACHIEVED.

Analog computers haven been a thing for a long time, and for certain applications they remained much better to use over digital ones. And they still may be in use in those applications.

Except for what a typical person uses a computer for, analog computers have little value. What we have is good enough and our eyes and brain sorts out the rest.

 

[DJJC]

No, please understand... Computer processors are analogue. They just behave digitally.

 

[DSzymborski]

What does any of this have to do with the price of tea in China?

What are you actually trying to discuss?

 

[DJJC]

Basically... That digital, analogue modelling could be used to create a software CPU. Imagine a software CPU sitting inside Bill Gates' Windows?

 

[DJJC]

The reason this has not yet been done, is devastating. Korg, Roland, Arturia, Universal Audio. All thought that CPUs are digital, when they are not, they are analogue.

 

[DJJC]

An explanation from the internet... "Arguably, a microprocessor is entirely analog. "Digital" is a simplification applied to what are essentially all analog signals, albeit analog signals with defined thresholds"

 

[Lamarr the Strelok]

I can plug an electric guitar into one of my tube(valve) amps and get all analog sound. If I plug in to one of my modeling amplifiers the input and output are analog but the guitar signal gets converted to digital then analog again before it comes out of the speaker.

your internet explanation sounds like ad copy for a software company that makes modeling software. They trip over each other trying to tell everyone their software is more 'analog' or 'natural'sounding than others. All cpu's I know of are digital devices. Please list an analog cpu ;that sounds interesting.

 

[DJJC]

That's not fair. It sounds like you are trying to fail my musical understanding, along with computational understanding, accusing me of advertising. I am a music producer and DJ. I also have a kick ass, 14 core, Intel PC with 128gb RAM. Now... Don't you understand? CPUs are ANALOGUE, and they BEHAVE digitally. CPUs use analogue signals to define 1 and 0. Shockingly, if you search on Google, there is false claim after another that CPUs are digital, when they are not, they are analogue. Everyone needs to get word about, because, imagine a 1000 core software CPU!!

While I can kinda appreciate your enthusiasm for discovering the "truth" about how things work, the thing is, anybody who's taken some college level education on electronics already knows that an actual digital circuit, where the value can change instantaneously, is physically impossible. And the math behind actual "digital" signals is https://en.wikipedia.org/wiki/Fourier_series

This is kind of like going around telling people that electrons don't actually orbit the nucleus of an atom like planets in our solar system orbit the sun.

Or how this video explains it:

And yes, we can have 1,000 core CPUs. I even did some napkin math: you can make a million core CPU in the same number of transistors as it takes to make an 8-core CCD of a Ryzen 7000 processor. But you'd have to make them out of an 8-bit CPU from the late 70s.

However, you're a music producer. And as far as I know, you have little to no actual knowledge of electronics. So I hate to be mean, but knowing this "fact" doesn't make you an expert here. So calm down and shuffle this as a bit of trivia to tell to your friends.

EDIT: Here's a couple of other things to blow your mind with

• Components don't actually instantly change state. Everything has "propagation delay", which is something you have to account for when designing high-speed electronics
• The electrical signals doesn't travel anywhere near as fast as the speed of light in copper. It's more like 2/3rds that (though it depends on a lot of things). This actually matters in high speed signaling. Ever see squiggly lines on a PCB of a motherboard these days? These are to intentionally delay the signal so it arrives at the same time as whatever else it's associated with.

THIS... Is the EXACT problem I am facing. Study harder computer boffin... Yet ANOTHER quote from the internet, shattering your misconception... "Internally all microprocessors are analog. They use electrical voltages to represent digital states of 0 and 1. All of their logic is designed around manipulating those voltages to produce digital behavior." See? Also, thanks for the research! Now... Can someone please kindly tell Microsoft, Intel and AMD about this WORLD CHANGING opportunity?

Uh...

My post meant that anyone who went through college in say Electrical Engineering, Computer Engineering, or similar already knows this because it's on the "basic" courses they have to take (basic, after like a year of calculus and such)

So rest assured, they already know this. No need to tell them.

 

[DJJC]

Look... I understand your enthusiasm. However MODERN DAY CPUs ARE ANALOGUE. It's frikking hardware. They use analogue signals to represent 1 and 0.

Uh yes, this is something college kids studying electronics learn within the first 2-3 years of their study.

You didn't discover anything new or groundbreaking here. I'm sorry.

 

[DJJC]

Please read this discussion... https://electronics.stackexchange.c...tirely,analog signals with defined thresholds.

 

[DJJC]

Oh... Ok Hotaru... I thought you are denying these facts haha. Sorry, you are very intelligent.

 

[DJJC]

Ok... SO the time is now, everyone. Intel and AMD and NVIDIA, could and should start making software CPUs and GPUs.

 

[hotaru.hino]

They do, that's how they design the actual hardware. i.e., they use simulators to verify the design, put it on an FPGA or a similar device to test it as much as possible to see how it might work in the real world, then make the actual hardware.

 

[DJJC]

Yeah I know, however they do not use digital, analogue modelling. They use equations.

At this point I'm throwing in the towel on this topic.

If you really think you know more than what engineers and researchers with decades of experience know, then why don't you reach out directly to them?

 

[DJJC]

What I mean is... You could make a 1000 core Intel or AMD CPU inside, for example, Bill Gates' Microsoft Windows.

 

[DJJC]

Honestly... I am not trying to get your back up. Software, digitally representing a hardware processor, I am talking about.

 

[DSzymborski]

As this has becomes a soapbox for personal stream-of-consciousness, I'm locking the thread. The best place to continue this would be on your personal blog or on social media.
