Question

In this assignment, try to understand the assembly code instructions addv1.sim1. In #addv1.sim1 using only one acc register, addition of two numbers have been done.

For the assignment, you need to write assembly code, whose corresponding c code is as followings.

int a = 0;

int b = 5;

int c = 10;

a = (b*2)^c + c;

exit(0);

Only operations that are allowed is to use add, load, store, shift, and xor.
