Addition of Two 8-bit Numbers using 8085 Microprocessor

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

Algorithm

1. Load the accumulator with the first data.
2. Move data of accumulator to register B.
3. Load the second data into the accumulator.
4. Add the content of register B with the content of accumulator.
5. 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.
