In this tutorial, we will learn how to find the maximum of two 8-bit numbers using 8086 Microprocessor? By Raju Singh Bhati Last updated : May 22, 2023

Problem Statement

To find maximum of two 8-bit numbers using 8086 Microprocessor.

Algorithm

1. Move the first number to register AL.
2. Move the second number to register BL.
3. Compare the content of register AL and BL if not carry goto step 5 otherwise goto step 4.
4. Move the content of register BL to the register AL.
5. Move the content of register AL to the memory location.

Program

MOV     AL, [0600]
MOV     BL, [0601]
CMP     AL, BL
JNC **
MOV     AL, BL
** MOV [0602], AL
HLT

Observation

INPUT: 
0600: 12
0601: 21

OUTPUT: 
0602: 21

Hence successfully find the maximum of two 8-bit numbers using 8086 Microprocessor.
