Is it possible to build your own CPU

In my other post someone thought that I was building a CPU (I wasn't planning to) but now I'm wondering if it is possible. If it is can someone give me some links on how to do it? I don't care how old of architecture it would be or what it could run (maybe MS-DOS?) and if so, how would I connect it to say a home built GPU and motherboard (or bought ones) and how I could get it to post. Maybe a guide on building a PC from scratch. Thanks

In theory it's possible, but it'd take up a huge amount of space and not even be able to run MS-DOS.

If you're asking on this forum it will be far beyond your capabilities (no offense) but there is a lot of really interesting online information about how it all works.

I don't think someone at 12 would be able to do it (looking at your profile) no offense.

look up where to get transistors. then look up how to make simple adders, logic gates and the likes. then look up how to make a SRAM cell. then figure out a way to have them interconnected. congratulations you have a touring complete machine.

Is it any good? no. Is it fun to do? hell yeah. ive seen it done by some fellow students. it required manual selection of instructions and operands, and worked slower than an FX4100 (if tahts even possible), BUT, given infinite time, would be just as good as a supercomputer :)

Yep, you can.

 

You're just gonna need lots and lots of money.

I don't care how slow it is really. If it works, then I don't mind. Even if it could just make an led blink on and off (How would you program that?) it would be super cool

There have been people who've made 4, 8, and 16 bit computers in Mincraft and Dwarf Fortress. Sure it's not physical, but that just means it's possible for someone to do with transistors.

 

It's just going to take a few months.

Making something in a video game doesn't translate to real life....

You can just do that with a battery, 3 wires, a switch and an LED... xD

You technically don't need a CPU to do that, just basic electrical components.

I don't care how long it will take, but it would be nice if it would be around or smaller than 50 x 50 cm

You'd want a resistor as well tbf :P

That's actually really easy to make using a simple timer and LED driver. Cost is less than $10. And it would be the size of whatever breadboard you build it on.

Building your own CPU however... well I can find you a textbook on digital electronics if you want to get started.

Well, it would be cool if it could make more complicated desicisions as well like analog signals to motors or similar. Decision making in itself would be amazing. Anyone find any links?

We've now got three different subjects going on, an Asian fox and motorbike fetish, two guys talking about Norway invasions and then some other people talking about body building... This thread is turning into a free for all fetish infested Norwegian circle jerk.
