Yea shure you guys think that nasa was able to land something on the moon with either remote control or fully automated and then after a sucessfull landing of a unmanned craft deploy a mirror angled so you can bounce back laser but you also say that PEOPLE were never up there? What is even needed as proof for you people?
It literally says “32 bit RISC-V homemade CPU out of discrete components”.
I dont know how you would stretch the definition of cpu in form of discrete components but yea current processors also stray from the definition of a alu and a control unit and registers since people call the different cores cpus. But even a Mikrocontroller has a all that.
You need a cpu to run linux. If you just want to rin a “program” you can do that with logic gates and no alu or control unit but that would limit the form of your program to exactly that circuit.
