Problem $2)$

We want to write a SimARM assembly program implementing following function, where $x,y$ and

$f$ are $32-$bit memory references

$f=(x^2-4y^2+xy)$

a$)$ What condition must $x$ and $y$ satisfy in order to avoid a $32-$bit result overflow?

b$)$ Assuming no overflow, write the assembly program using the SimARM instruction set.
