What is 8086 instruction set? the 8086 instruction set is a group of commands that the intel 8086 microprocessor uses to perform tasks. it includes a variety of instructions that allow developers to create software for many different tasks, from simple math to more complex processing. * program execution transfer instructions into (interrupt on overflow): this instruction generates type 4 interrupt (i.e. interrupt for overflow) and causes the 8086 to do an indirect far call a procedure which is written by the user to handle the overflow condition. Efficient software development for the microprocessor requires a complete familiarity with the instruction set, their format and addressing modes. here in this chapter, we will focus on the addressing modes and instructions formats of microprocessor 8086.

Study of instruction set is required to write instructions in machine code that can be recognized and executed by a central processing unit. the knowledge will help you write lines of code or program by which you will be able to tell the processor, the sequence of operations to be performed. Chapter 2 basic architecture of the 8086 and 8088 microprocessors 8086 microprocessor is an enhanced version of 8085 microprocessor that was designed by intel in 1976. it is a 16 bit microprocessor having 20 address bus so; it can address up to 220 =10485. A subroutine is a special segment of program that can be called for execution from any point in a program. an assembly language subroutine is also referred to as a “ procedure ”. to branch a subroutine the value in the ip or cs and ip must be modified. after execution, we want to return the control to the instruction that immediately. Instructions that process data strings use the si and di registers together with ds and es respectively in order to distinguish between the source and destination addresses.
