Description:

(VisUAL/Keil Tools Portion):

In this part, you will design a program that will implement a 128-bit adder. Move 32-bit numbers into r0-r7 (using MOV or MVN) and then perform the 128-bit addition as seen below. Make sure to keep track of the carries and confirm that the addition result is correct for your chosen 128-bit numbers (you will need to update the condition codes with the add instructions by appending S to any instruction that needs to potentially carry from one column to the next and an instruction to use that carry in the addition).
