Maximum of Two 8-bit Numbers in 8085 Microprocessor

Given two 8-bit numbers, we have to find the maximum number among them in 8085 Microprocessor.


  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 reset then jump to the step 7.
  6. Copy the content to accumulator.
  7. Now load the result value in memory location from accumulator.


LDA     2050
MOV     B, A
LDA     2051
JNC **
MOV     A, B
** STA 2052




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