In order to enjoy this luxury, someone has to translate our symbolic programs into binary code that can execute as-is on the target computer. But, writing programs in assembly is far easier and safer then writing in binary. Both languages do exactly the same thing, and are completely equivalent. This experience will give you a taste of low-level programming, as well as a solid hands-on overview of the Hack computer platform.Įvery 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. We will then use a supplied CPU Emulator (a computer program) to test and execute our programs. Taking a similar approach, in this module we assume that the Hack computer and machine language have been built, and write some low-level programs using the Hack machine language. Such experiments can give us a good appreciation of the bare bone "look and feel" of the new computer, and lead to decisions that may well change and improve both the hardware and the language designs. For example, we can write a Java program that emulates the yet-to-be-built computer, and then use it to emulate the execution of programs written in the new machine language. As it turns out, this can be done before the computer itself is actually built. When you complete the course, you’ll have a finished project that you’ll be proud to use and share.Ī 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. 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. *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. You can watch a TED talk about this course by Googling "nand2tetris TED talk". The course can be completed in six weeks, but you are welcome to take it at your own pace. 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 consists of six modules, each comprising a series of video lectures, and a project. The hardware simulator, as well as other software tools, will be supplied freely after you enroll in the course. 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. Therefore, we assume no previous computer science or engineering knowledge, and all learners are welcome aboard. 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. In the process, you will learn - in the most direct and constructive way - how computers work, and how they are designed. 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 this project-centered course* you will build a modern computer system, from the ground up. ![]()
