Dear community,
Let’s just say I’m a country that wants to create my own CPU only using knowledge/tech/techniques that are in the open and nothing proprietary. When I said CPU, let’s just say something that can run a C program, and eventually the linux kernel.
Is creating one out of publicly accessed knowledge and resources even possible, and how minuscule the tolerance need to be? Is there even a successful open CPU project out there?
I’m asking this because of an anxiety that I have when knowing only several companies in the world know how to create a CPU.


This is a possible thing, there are youtube videos of people making cpus on breadboards. Idk if mass producing them would be practical though without any proprietary parts from the global supply chain
yes, but fabricating a CPU on a small enough form factor is still an issue, afaik
