Assembly x64 Programming in easy steps shows how to write code to create your own computer programs. It contains separate chapters demonstrating how to store and manipulate data in 64-bit registers, how to control program flow, and how to create reusable blocks of code in program functions. It includes demonstrations of parallel processing with 128-bit Streaming SIMD Extensions (SSE) and 256-bit Advanced Vector Extensions (AVX).

Assembly x64 Programming in easy steps has an easy-to-follow style that will appeal to anyone who wants to begin programming in modern x64 Assembly language on Windows. The code in the listed steps within the book is color-coded, making it easier for beginners to grasp. There are complete step-by-step example programs that demonstrate each aspect of coding, together with screenshots that illustrate the actual output when each program is executed.

Includes free, downloadable source code to get you started straightaway!

Summary

Introducing Assembly

Assembly (ASM) is a low-level programming language for a computer or other programmable device. Unlike high-level programming languages such as C++, which are typically portable across different systems, the Assembly language targets a specific system architecture. This book demonstrates Assembly programming for the x86-64 computer system architecture – also known as “x64”, “Intel64” and “AMD64”.

Assembly language code is converted into machine instructions by an “assembler” utility program. There are several assemblers available but this book uses only the Microsoft Macro Assembler (MASM) on the Windows operating system.

The Assembly example programs in this book are created and tested in the free Community Edition of the Microsoft Visual Studio Integrated Development Environment (IDE).

At the heart of every computer is a microprocessor chip called the Central Processing Unit (CPU) that handles system operations, such as receiving input from the keyboard and displaying output on the screen. The CPU only understands “machine language instructions”. These are binary strings of ones and zeros, which are in themselves too ob...
