Question $3\mathrm{.}1$

What is the clock cycle time with this improvement?

$($hint: a block, for example ALU, is functional only if all of

its inputs are ready; please pay attention to which input

arrives last.$)$

Question $3\mathrm{.}2$

If the delay caused by sign$-$extend unit is $220$ ps$.$ What

would be the clock$-$cycle time with this change? $($the

delay caused by ALU is still $150+120$ ps$)$

Question $3\mathrm{.}3$

If the delay caused by Control unit is $250ps$ and of ALU

Control unit is $100$ ps$.$ What would be the clock cycle

time with this change? $($the delay caused by ALU is still

$150+120$ ps and the delay caused by sign$-$extension

unit is $220$ ps$)$

$1935$ ps

$1930$ ps

$1835$ ps

$2055$ ps
