Examine the difficulty of adding a proposed lwi.d rd$,$ rs$1,$ rs$2($Load With Increment$)$ instruction to RISC$-$V$.$ Interpretation: Reg$[$rd$]=$Mem$[$Reg$[$rs$1]+$Reg$[$rs$2]]$

$4\mathrm{.}11\mathrm{.}1[5]<4\mathrm{.}4>$ Which new functional blocks $($if any$)$ do we need

for this instruction?

$4\mathrm{.}11\mathrm{.}2[5]<4\mathrm{.}4>$ Which existing functional blocks $($if any$)$ require

modification?

$4\mathrm{.}11\mathrm{.}3[5]<4\mathrm{.}4>$ Which new data paths $($if any$)$ do we need for

this instruction?

$4\mathrm{.}11\mathrm{.}4[5]<4\mathrm{.}4>$ What new signals do we need $($if any$)$ from the

control unit to support this instruction?
