NASM x86_64 Assembly: Write Low-Level Programs from Scratch

Ever wondered what actually happens when your code runs directly on the hardware? Understanding assembly language gives you unmatched insight into how computers execute instructions and manage memory at the lowest level. This text-based course guides you from absolute beginner to writing functional x86_64 assembly programs using the Netwide Assembler (NASM). You will transition from high-level abstractions to a deep, practical understanding of CPU operations, registers, and memory management. What you'll learn: - Understand the fundamental architecture of x86_64 processors, including registers and memory layout. - Write clean NASM syntax to perform arithmetic, logical operations, and data movement. - Implement control flow using conditional jumps, loops, and comparison instructions. - Interact directly with the operating system using system calls for input and output. - Apply standard calling conventions to write modular code and interface with high-level languages. - Debug assembly programs step-by-step using modern command-line debugging techniques. The course starts with essential low-level concepts and terminology before guiding you through the mechanics of writing, assembling, and executing your first programs. You will progress from simple operations to structured code design through clear explanations and structured text-based code exercises. This course is designed for aspiring systems programmers, computer science students, and curious developers with no prior assembly experience.
