Trace the execution of the "beq $s$0,$ $zero, Exit" in the following MIPS assembly code segment on

the single$-$cycle MIPS implementation by answering the questions about values of the control and data

signals and registers and memory locations.

The code segment starts at memory location $({0000}_{0000})16$ and ends at memory location $({0000}_{1014}{)}_{16}.$

Show values of control signals and register numbers in binary.

Show data signals, register contents, and memory addresses in $8-$digit hexadecimal. Use X for don't care

and unknown values.

$00001000$ Loop: beq $s$0,$ $zero, Exit

$00001004$ lw $$t0,100($$$s0)$

$00001008$ sw $t$0,200($$s$0)$

$0000100$C add $s$0,$ $zero, $zero

$00001010,$ j Loop

$00001014$ Exit:

Assume that the decimal values $4$ and $8$ are initially stored in register $$s0$ and data memory location

${104}_{10},$ respectively.

Most of questions are based on the execution of the first instruction $$beq $s$0,$ $zero, Exit" unless

otherwise specified.
