3.2. 3.2 The 80×86 Addressing Modes
The 80×86 processors let you access memory in many different ways. Until now, you've only seen a single way to access a variable, the so-called displacement-only addressing mode. In this section you'll see some additional ways your programs can access memory using 80×86 memory addressing modes. The 80×86 memory addressing modes provide flexible access to memory, allowing you to easily access variables, arrays, records, pointers, and other complex data types. Mastery of the 80×86 addressing modes is the first step toward mastering 80×86 assembly language.
When Intel designed the original 8086 processor, it provided it with a flexible, though limited, set of memory addressing modes. Intel added several new addressing ...
