AIM: Write a program to find 2‘s complement of an 8 bit number. Objective: To understand the complement process To write algorithm for 1’s complement To develop the assembly language program to find 2’s complement To analyse the result and interpret errors if any Requirement: Operating System- Windos, Linux 8085 simulator Theory 2’s complement of a number is found in following ways: Do the 1’s complement of the given number Add ‘1’ to this 1’s complement Example: Find the 2’s complement of 59h Number 59h                       =  01011001 1’s complement               = 10100110 Adding ‘1’ = 10100110 + 1 = 10100111 So, 2’s complement of 59h = A7h Algorithm: Get a number in the accumulator Complement using CMA Add ‘1’ to this to get 2’s complement Save the result Assembly language
