Suppose $r=056789$ABC, find the result of the following operations. These

operations run independently.

$(1)$ RBIT $r1,$ re

$(2)$ REV $r1,r$

$(3)$ REV$16r1,r$

$(4)$ REVSH r$1,$ r$0$

Translate the following $C$ statement into an assembly program, assuming $16-$bit

signed integers $x,y$ and $z($i$.$e$.,$ signed short$)$ are stored in $32-$bit register r$0,$ r$1,$ and

$r2,$ respectively.

$x=x**y+z-x$

Translate the following $C$ statement into an assembly program, assuming $16-$bit

unsigned integers x and y $($i$.$e$.,$ unsigned short$)$ are stored in register r $0,$ and r $1,$

respectively.

$x=x\%y$

Write an assembly program that calculates the value of the following given

polynomial, assuming signed integers x and y are stored in register $r0$ and $r1,$

respectively.

$y=3x^3-7x^2+10x-11$

Write an assembly program that calculates the remainder of the division between two

unsigned $32-$bit integers.

Explain why Cortex$-$M processors do not provide any left rotation instructions. They

only offer ROR $($rotate right$)$ and RRX $($rotate right extended$).$

Explain the difference between the Barrel shifter's role in the following instructions:

$(1)$ ANDS $r1,r2,r3,$ LSL #$3$

$(2)$ ADDS r$1,$ r$2,$ r$3,$ LSL #$3$

Write an assembly program that reverses the byte order of a register without using

the REV instruction.

Write an assembly program that swaps the upper halfword and the lower halfword

of a register.

Implement the BIC $($bitwise clear$)$ instruction by using other assembly instructions.

Suppose Mask $=000000F0F$ and $P=0$ABCDABCD. What are the results of the

following bitwise operations?
