Intel 8086 Addressing Style 0 0 0 0 Segment reg + Offset Generates a 20-bit memory address Offset Segment base
Sample Instructions Accumulator type AX:= AX + BX AX:= AX + M String operations Move a char string (Uses SI and DI) Starting from 80386, x86 became a true 32-bit architecture. Its instruction set broadly defines the IA-32 architecture. Architecture vs Organization CPU architecture refers to the programmer’s view, i.e. primarily the instruction set. The same architecture can be implemented in many different ways. True for IA-32 too.
