bitwise operations

Shifting a positive integer left by i bits gives the same result as multiplying the same integer by $2^i.$

$i{2}^{i}N{2}^i=N>>$iNN$8x20\frac{N}{16}x21N{2}^i=N$

Likewise, shifting a positive integer right $by$ i bits gives the same result $as$ dividing the same integer $by{2}^i.$

$N{2}^i=N>>i$

Given $an$ integer $N$ stored $inX19,$ write a program that stores the result $ofN8inx20$ and the result $of\frac{N}{16}inx21.$ Use the $\text{'}+\text{'}$ button

under the Registers display $to$ initialize register value for $X19.$

$Ex$: $If$ the value $ofX19is$ initialized $in$ the simulator $as64,$ the results are stored $inX20$ and $X21$ :

Note: Shift$-$right performs $an$ integer division; therefore, digits after the decimal point are ignored.
