Question

Addition of two 8 bit numbers without carry in 8085

Answer 1

Addition of two 8 bits numbers in 8085 Microprocessor

Here, we are going to learn how to find the addition of two 8 bits number without carry using 8085 microprocessor?



Problem statement:

To perform addition of two 8 bits numbers without carries using 8085 microprocessor.

Algorithm:

Load the accumulator with the first data.

Move data of accumulator to register B.

Load the second data into the accumulator.

Add the content of register B with the content of accumulator.

Now load the result value in a memory location.

Program:

LDA 2050

MOV B,A

LDA 2051

ADD B

STA 2052

Observation:

INPUT:

2050:04

2051:02

OUTPUT:

2052:06

Hence we successfully added two 8 bits numbers.
