$12\mathrm{.}14\mathrm{.}5$: $[10].$

In the exercise, we examine in detail how an instruction is executed in single$-$cycle datapath. Problems in this exercise refer to a clock cycle in which the processor fetches the following instruction word: $0$xadac$0014.$

For context: The encoded instruction is sw $t$4,20($$t$5)$

$($a$)$

What are the values of the ALU control unit's inputs for this instruction?

$($b$)$

What is the new PC address after this instruction is executed? Highlight the path through which this value is determined.

$($c$)$

For each mux, show the values of its inputs and outputs during the execution of this instruction. List values that are register outputs at Reg $[$xn$]$

$($d$)$

What are the input values for the ALU and the two add units?

$($e$)$

What are the values of all inputs for the registers unit?
