X86-64 Core Architecture

Chapter

Abstract

Chapter 17 explores the fundamentals of the x86-64 core architecture. It begins with an overview of its internal architecture, which includes details of the execution units, general-purpose registers, instruction operands, and memory addressing modes. Next is a discussion of the differences between the x86-64 and x86-32 execution environments that programmers need to be aware of when coding assembly language functions. The final section of this chapter encapsulates the x86-64 instruction set. All of the material in this chapter assumes that you have a basic understanding of the x86-32 core architecture and the x86-32 instruction set.
