Introduction to Computer Organization: An Under the Hood Look at Hardware and x86-64 Assembly

Rate this book
This hands-on tutorial is a broad examination of how a modern computer works. Classroom tested for over a decade, it gives readers a firm understanding of how computers do what they do, covering essentials like data storage, logic gates and transistors, data types, the CPU, assembly, and machine code.

Introduction to Computer Organization gives programmers a practical understanding of what happens in a computer when you execute your code. You may never have to write x86-64 assembly language or design hardware yourself, but knowing how the hardware and software works will give you greater control and confidence over your coding decisions. We start with high level fundamental concepts like memory organization, binary logic, and data types and then explore how they are implemented at the assembly language level.

The goal isn’t to make you an assembly programmer, but to help you comprehend what happens behind the scenes between running your program and seeing “Hello World” displayed on the screen. Classroom-tested for over a decade, this book will demystify topics


Author Robert Plantz takes a practical approach to the material, providing examples and exercises on every page, without sacrificing technical details. Learning how to think like a computer will help you write better programs, in any language, even if you never look at another line of assembly code again.

Assembly code learning starts on page 146.

x86-64 learning with gcc, g++, gdb, and as.

I'm using this to learn all of those. I'm not gonna lie.... the logic chapters in these nand2tetris type books are insanely dry and hard to follow. I hate to admit it, but my Philosophy instructor was useful, and taught truth tables in a followable fashion.

The first HALF of the book is logic related. Yes, I get it, you need to know the basics. But dayumn 6-7 chapters or truth tables incarnations and iterations explained.

The last half actually teaches you how to sus through assembly code from your C files. It's actual assembly code.
