guide, we describe the basics of 32-bit x86 assembly language programming, covering a small but useful subset of the available instructions and assembler directives. However, real x86 programming is a large and extremely complex universe, much of which is beyond the useful scope of this class. For example,
The architecture was extended from 16 bits to 32 with the introduction of the 80386 in 1985, and its associated coprocessor, the 80387. The ‘386 and its associated coprocessor, were available in 16-bit external bus versions, the SX series. The 80486 in 1989 combined the coprocessor and the main processor on the same chip. In

This guide describes the basics of 32-bit x86 assembly language programming, covering a small but useful subset of the available instructions and assembler directives. There are several different assembly languages for generating x86 machine code. The one we will use in CS216 is the Microsoft Macro Assembler (MASM) assembler.
