8085 Program to Add two 8 Bit numbers

In this program, we will see how to add two 8-bit numbers using 8085 microprocessor.

Problem Statement

Write8085 Assembly language program to add two 8-bit numbers and store the result at locations 8050H and 8051H.

Discussion

To perform this task, we are using the ADD operation of 8085 Microprocessor. When the result of the addition is the 1-byte result, then the carry flag will not be enabled. When the result is exceeding the 1-byte range, then the carry flag will be 1

We are using two numbers at location 8000H and 8001H. When the numbers are 6CH and 24H, then the result will be (6C + 24 = 90) and when the numbers are FCH and 2FH, then the result will be (FC + 2F = 12B) Here the result is exceeding the range of 1-byte.
