In this post, we will show a simple program which adds two numbers from two registers and save it into third register. So this program does following,
- Copy first number (ex. decimal 6) to register R0
- Copy second number (ex. decimal 3) to register R1
- Add those two numbers from register R0 and R1 (6+3) and save the addition to register R2 (ex. decimal 9)
So, the final program would look as,
MOVS R0, #6 MOVS R1, #3 ADDS R2, R1, R0
Note: This instructions works for ARM.
