Problem: To find square root of a number using 8085 Microprocessor.

Algorithm:

1. Assign the value of register D and E with 01H.
2. Load the number from memory.
3. Subtract the content of accumulator with the content of register D.
4. Check if the value of accumulator is zero if yes goto step 8.
5. Increase the content of register by 02H.
6. Increase the content of register by 01H.
7. Goto step 3.
8. Move the content of register E to accumulator.
9. Store the result of register E to the memory.
10. Terminate the program.

Program:

    MVI     E, 01
    MVI     D, 01
    LDA     2050
    **** SUB D
    JZ  ***
    ADI     D, 02
    INC     E
    JMP ****
    *** MOV A, E
    STA     3050
    HLT

Observation:

    INPUT:
    2050 : 09

    OUTPUT:
    2051 : 03

Hence, we successfully find the square root of an 8-bit number using 8085 Microprocessor.
