Modern Computer Architecture and Organization, by Jim Ledin. Published by Packt Publishing.
Most modern personal computers contain a processor supporting either the Intel or AMD version of the x86 32-bit and x64 64-bit architectures. Almost all smartphones, smart watches, tablets, and many embedded systems, on the other hand, contain ARM 32-bit or 64-bit processors. This chapter takes a detailed look at the registers and instruction sets of all of these processor families.
After completing this chapter, you will understand the top-level architectures and unique attributes of the x86, x64, 32-bit ARM, and 64-bit ARM registers, instruction sets, assembly languages, and key aspects of legacy feature support in these architectures.
This chapter covers the following topics:
- x86 architecture and instruction set
- x64 architecture and instruction set
- 32-bit ARM architecture and instruction set
- 64-bit ARM architecture and instruction set
hello_x86.asm is the 32-bit x86 hello assembly language program.
hello_x64.asm is the 64-bit x64 hello assembly language program.
hello_arm.s is the 32-bit ARM hello assembly language program.
hello_arm64.s is the 64-bit ARM hello assembly language program.
