Problem statement:

To find minimum of two 8bit numberusing 8085 microprocessor.

Algorithm:

1. Load the accumulator with the first data.
2. Move the content of accumulator to register B.
3. Load the accumulator with the second data.
4. Compare the content of accumulator with the content of register B.
5. If carry flag is set then jump to the step 7.
6. Copy the content to accumulator.
7. Now load the result value in memory location from accumulator.

Program:

    LDA     2050   
    MOV     B, A
    LDA     2051
    CMP 
    JC **   
    MOV     A, B
    ** STA 2052

Observation:

    INPUT: 
    2050:05
    2051:02

    OUTPUT: 
    2052:02

Hence, we successfully find the minimum among two 8 bits numbers.
