$1-2$: Suppose that each of num$1,$ num$2,$ and num$3$ references a byte in memory and that an unsigned number is stored in each byte. Assume that the first number is no larger than $7($three significant bits$),$ the second number is no larger than $63($six significant bits$),$ and the third number is no larger than $127($seven significant bits$)\mathrm{.}1.$ Suppose we pack all three of these numbers into a $16-$bit word in the AX register, copying the low order three bits from num$1$ to bits $13-15$ of AX$,$ the low order six bits from num$2$ to bits $7-12$ of AX$,$ and the low order seven bits from num$3$ to bits $0-6$ of AX$.$ If numbers $5,57,$ and $111$ are at num$1,$ num$2,$ and num$3,$ respectively, what will be in AX after packing $?\_\_\_\_\_\_\_\_\_\_\_\_\_\_($hex$)$ Show work$\mathrm{.}2.$ Give an $80$x$86$ code fragment that packs all three of these numbers into a $16-$bit word in the AX register as described above. Hint: Use logical and shift instructions. Be sure to include appropriate comments. $2.$ Give an $80$x$86$ code fragment that unpacks the $16$ bit number in the AX register into three$-$bit, six$-$bit, and seven$-$bit numbers, padding each value with zeros on the left to make eight bits, and storing the resulting bytes at num$4,$ num$5,$ and num$6,$ respectively. $$ The value stored in AX must NOT be altered after unpacking. $$ Do NOT use other registers or memory labels. $$ Be sure to include appropriate comments.
