Problem – Write an assembly language program to sum two 8 bit numbers without using carry operation in 8085 microprocessor.

Algorithm:

1) Load the first number to the accumulator through memory address C040.

2) Move the content of accumulator to the register B.

3)Load the second number to the accumulator through memory address C042.

4) Add the content of accumulator and register B and result will be stored at the accumulator.

5) Store the result from the accumulator to the memory address C043.

6)Terminate the program.

Explanation:

LDA C040: This instruction will load the number from memory to the accumulator.

MOV B, A: This instruction will move the content of accumulator to the register B.

LDA C042: This instruction will load the number from memory to the accumulator.

ADD B: This instruction will sum the content of the accumulator with the content of the register B.and store the result into accumulator.

STA C043: This instruction will store the content of accumulator to the memory address 2052.

HLT: This instruction will terminate the program.

Hence we successfully sum the two 8 bit numbers without carry using 8085 microprocessor.

Input : C040=02
C042 = 04
Output : C043 = 06
