8085 program to find 1's and 2's complement of 8-bit number

In this program we will see how to find 1's complement and 2's complement of an 8-bit number.

Problem Statement

Write 8085 Assembly language program to find 1's complement and 2's complement of a number stored in 8000H.

Discussion

8085 has an instruction CMA. This instruction complements the content of Accumulator. For 1's complement CMA instruction is sufficient, and for 2's complement we have to increase the number by 1 after complementing.

We are taking the number from 8000H and storing the 1's complement at location 8050H, and 2's complement to 8051H.
