This 8-bit Processor Built in Minecraft can Run its Own Games

Computer chips are so tiny and complex that it can be difficult to remember the physical concepts that make them. They aren't just a bunch of ever-increasing numbers. For a real-world (well virtual) example, check out the most recent version of a computer processor built exclusively for the Minecraft game engine.



Minecraft builder "Sammyuri" spent seven months creating what they call the Chungus 2, an enormously complex computer processor that exists within the Minecraft game engine. This isn't even the first time that a computer processor has been virtually rebuilt inside Minecraft however, the Chungus 2 (Computation Humongous Unconventional Number and Graphics Unit) could very well be the largest and the most complex, simulating an 8-bit processor with 1 hertz clock speed and an adabyte of RAM.



Minecraft processors utilize the physics engine used in the game to recreate the design of real processors on a macro level, with materials including redstone dust, torchers, pistons, repeaters and other basic machines. To give you a sense of the size of the block, each one in Minecraft is one virtual meter across. This means that it's about the same size as the size of a cruise ship or a skyscraper, if this model could be recreated in the real world.



When connected to an in-game 32x32 "screen" and "controller" (manipulated by an avatar of a Minecraft avatar that jumps on block-sized buttons) The Chungus 2 can play interchangeable 2D games like Tetris, Snake, or even a graphing calculator. Some programs need the Minecraft server to be artificially speeded up to make the processor fast enough to use. Every program is developed virtually in Minecraft, plugging into the computer like an arcade game cartridge that is similar to a freight train.



This project is a stunning example of computer science in action. It's done in a way that demonstrates its principles quickly and visually. The video showcasing the Chungus 2 is impressive enough. If you'd like to see the project in action you can download it and run it on your server at mc.openredstone.org. If we hold off for several years, we may obtain a Minecraft CPU that's powerful enough to run Minecraft, at which the universe is likely to explode.
