64‑Bit Assembly in Practice: Master Low-Level Programming

Have you ever wondered what really happens under the hood of your computer when you run your favorite application? Have you asked yourself what lies beyond high-level programming languages, and what real power you could unlock if you spoke the machine’s native tongue? If you’ve ever been curious about how your processor thinks, how memory is moved around, or how to squeeze every last drop of performance from your hardware, then 64‑Bit Assembly in Practice: Master Low-Level Programming and Performance Optimization on x86‑64 Systems by Emrick H. Lowell might just be the book you’ve been searching for.
Why settle for being just another programmer when you can become the one who understands the foundations everyone else stands on? Do you know why some programs run blazing fast and others crawl, even when written in the same language? Could it be the compiler’s fault? Or is there something deeper, something only a low-level view can reveal?
This book doesn’t just throw instructions and syntax at you — it challenges you to think like the CPU. Have you ever debugged a tricky bug and wished you knew what was happening in the registers and the stack? Wouldn’t you feel more confident if you could read and write assembly code as easily as you handle Python or C++?
In 64‑Bit Assembly in Practice, you’ll learn step by step how to harness the power of the x86‑64 architecture — the very heart of modern PCs and servers. You’ll discover how to:

• Write efficient, robust assembly code that interacts directly with your operating system and hardware.
• Understand calling conventions, stack frames, and register usage to master how functions really work behind the scenes.
• Optimize C and C++ programs using inline assembly, turning good code into great code.
• Debug at the machine level, gaining skills that few developers bother to acquire.
• Benchmark and profile your code, so you always know exactly where the bottlenecks hide.

But here’s the real question: Do you want to keep taking the compiler’s word for it, or do you want to peek behind the curtain and take control yourself? Imagine writing software that makes better use of your hardware, software that’s faster, leaner, and more secure — all because you understand what’s really happening in the CPU’s registers, memory, and instructions.
Emrick H. Lowell brings these concepts to life with real-world examples, practical exercises, and clear explanations that demystify this so-called “arcane” subject. You don’t need to be an expert to start — you just need curiosity and the willingness to think a bit deeper than the average developer.
So ask yourself: Are you ready to stand out from the crowd of high-level coders? Are you prepared to develop the skills that can land you a systems programming role, security job, or simply give you the satisfaction of knowing you truly get how computers work?
