Function units B$,$ D$,$ and E can be subdivided into two equal delay stages. If the expected occurrence of pipeline breaks is b $=0\mathrm{.}25$ and clock$-$ ing overhead is $0\mathrm{.}1$ns:

$($a$)$ What is the optimum number of pipeline segments $($round down to

integer value$)?$

$($b$)$ What cycle time does this give?

$($c$)$ Compute the pipeline performance with this cycle time.
