Problem Statement
Two's complement is an important concept in representing negative numbers. To turn a positive integer negative, flip the bits and add one.
Show how to calculate the two's complement of an integer. (It doesn't necessarily need to be a 32 bit integer.)
Let's start with the solution:
Step by Step solution about How to resolve the algorithm Two's complement step by step in the ARM Assembly programming language
Source code in the arm programming language
MOV R0,#0x0000000F
MOV R1,#1
MVN R0,R0 ;flips the bits of R0, R0 = 0xFFFFFFF0
ADD R0,R0,R1 ;R0 = 0xFFFFFFF1
