Use an Armv$8$ simulator for help!!

$5.$ Write the value of the $"$PC$"$ registers, flag registers and control signals for each executed instruction.

$6.$ Each instruction has different fields that are represented as binary in the machine. Write down the binary value of the field of each instruction.

$7.$ Write down the value of "ALU" input signal $($control signal$)?$

Question $2$:

Code $1$:

ADDI X$1,$ XZR$,$ #$10$

ADDI X$2,$ XZR$,$ #$20$

SUB X$3,$ X$1,$ X$2$

CBZ X$3,$ TARGET

ADDI X$1,$ XZR$,$ #$10$

ADDI X$2,$ XZR$,$ #$20$

SUB X$3,$ X$1,$ X$2$

CBZ X$3,$ TARGET

TARGET:

Code $2$:

ADDI X$1,$ XZR$,$ #$10$

ADDI X$2,$ XZR$,$ #$10$

SUB X$3,$ X$1,$ X$2$

CBZ X$3,$ TARGET

ADDI X$1,$ XZR$,$ #$10$

ADDI X$2,$ XZR$,$ #$20$

In addition to the question in Instructions $(5)$ to $(8),$ answer the following questions: How does Code $1$ differ from Code $2$ in terms of execution? $($Hint: Follow the "Zero" control output signal of ALU, the

"AND" gate, $"$OR$"$ gate, and control signal of the upper right "MUX"$)$
