About the content
What you’ll achieve: In this project-centered course* you will build a modern computer system, from the ground up. We’ll divide this fascinating journey into six hands-on projects that will take you from constructing elementary logic gates all the way through creating a fully functioning general purpose computer. In the process, you will learn - in the most direct and constructive way - how computers work, and how they are designed. What you’ll need: This is a self-contained course: all the knowledge necessary to succeed in the course and build the computer system will be given as part of the learning experience. Therefore, we assume no previous computer science or engineering knowledge, and all learners are welcome aboard. You will need no physical materials, since you will build the computer on your own PC, using a software-based hardware simulator, just like real computers are designed by computer engineers in the field. The hardware simulator, as well as other software tools, will be supplied freely after you enroll in the course. Course format: The course consists of six modules, each comprising a series of video lectures, and a project. You will need about 2-3 hours to watch each module's lectures, and about 5-10 hours to complete each one of the six projects. The course can be completed in six weeks, but you are welcome to take it at your own pace. You can watch a TED talk about this course by Googling "nand2tetris TED talk". *About Project-Centered Courses: Project-centered courses are designed to help you complete a personally meaningful real-world project, with your instructor and a community of learners with similar goals providing guidance and suggestions along the way. By actively applying new concepts as you learn, you’ll master the course content more efficiently; you’ll also get a head start on using the skills you gain to make positive changes in your life and career. When you complete the course, you’ll have a finished project that you’ll be proud to use and share.
- Week 1 - Introduction
Course introduction and overview, the roles of abstraction and implementation in systems design, the road ahead.
- Week 1 - Boolean Functions and Gate Logic
We will start with a brief introduction of Boolean algebra, and learn how Boolean functions can be physically implemented using logic gates. We will then learn how to specify gates and chips using a Hardware Description Language (HDL), and how to simulate the ...

General Course Information
- Week 2 - Boolean Arithmetic and the ALU
Using the chipset that we've built in the previous module, we will now proceed to build a family of adders -- chips designed to add numbers. We will then take a big step forward and build an Arithmetic Logic Unit. The ALU, which is designed to perform a whole ...
- Week 3 - Memory
Having built the computer's ALU, this module we turn to building the computer's main memory unit, also known as Random Access Memory, or RAM. This will be done gradually, going bottom-up from elementary flip-flop gates to one-bit registers to n-bit registers t...
- Week 4 - Machine Language
A critically important aspect of building a new computer system is designing the low-level machine language, or instruction set, with which the computer can be instructed to do various things. As it turns out, this can be done before the computer itself is act...
- Week 5 - Computer Architecture
Let's recap the last four modules: we've built some elementary logic gates (module 1), and then used them to build an ALU (module 2) and a RAM (module 3). We then played with low-level programming (module 4), assuming that the overall computer is actually avai...
- Week 6 - Assembler
Every computer has a binary machine language, in which instructions are written as series of 0's and 1's, and a symbolic machine language, also known as assembly language, in which instructions are expressed using human-friendly mnemonics. Both languages do ex...
