Design Your Own CPU From Scratch

What if you could build your own CPU instead of just learning how one works?

Design Your Own CPU From Scratch is a hands-on journey that takes you from simple digital building blocks to a complete working processor. Instead of only reading about how CPUs work, you’ll see how the pieces come together and experience the process of building one yourself.

At the heart of the project is the MT-4 CPU V1.1 — a complete 4-bit processor built from discrete digital components such as logic gates, flip-flops, counters and other fundamental digital building blocks. It is designed to store instructions, process information, perform calculations and logic operations, make decisions, and run programs.

And you don't just get the book !!

You also get the original simulation files and project resources, so you can open the actual design, run it, experiment with it, modify it, write your own programs, and see what happens.

Follow the original design, play around with it, break something, fix it, or use it as a starting point for your own ideas.

The project also takes you through the real journey behind building it—including experiments, problems, mistakes, fixes, and improvements along the way.

Perfect for engineering students, electronics enthusiasts, computer enthusiasts, makers, hobbyists, and anyone curious about how CPUs actually work.

You don't need to already know how to build a CPU.

A basic understanding of Digital electronics and computers, curiosity, and a willingness to experiment are enough to get started.

Don't just read about a CPU. Build one. Run it. Experiment with it. Make it yours.
