Question $1$: $(30$ points$)$

Translate each of the following combinations of $3-$address instructions to the

EISC code. Assume that the elements of the array are written over the length

of $8$ octets.

$x=a[i]$

$y=b[i]$

$z=x^{**}y$

$x=a[i]$

$y=b[x]$

$a[i]=y$

Here suppose that $p$ and $q$ are addresses.

$y={?}^{**}q$

$q=q+4$

${?}^{**}p=y$

$p=p+4$
