Question $1$

Represent the following conditional control instruction with two register transfer instructions with control functions:

If $($P $=1)$ then $($R$1$ R$2)$ else if $($Q $=1)$ then $($R$1$ R$3)$

Question $2(10$ points$)$

Draw the functional schematic of the hardware that implements the following statements:

$($x$.$y$)\text{'}+$ z : AR $$ AR $+$ BR

Where AR and BR are two n$-$bit registers, and x$,$ y$,$ and z are control variables.

Include the logic gates for the control function. $($Remember that the symbol $+$ represents an OR operation in a control or Boolean function, but it represents an arithmetic addition in a micro$-$operation.$)$
