Please answer the following well, use the screenshot sent to answer #$4$ and $5.$

#$4$: The current $[$CMOS$]$ chip requires $80$W of power. The packaging team tells you that they can dissipate

at most $50$W$.$ What clock rate do you tell your VLSI team to change the clock rate to$?$

#$5.$A certain program P requires $5$ s$.$ of CPU time, but must also do I$/$O of k bytes. I$/$O is of course

slower, and an I$/$O transfer of b bytes requires b $+10$ ms$.($the $10$ corresponds to a fixed startup time$).$

You may split I$/$O into any number of transfers $$ for example, k transfers of $1$ byte each, k$/2$ transfers

of $2$ bytes each, $...,1$ transfer of k bytes. The customer requires that you take at most $8$ s$.($total$)$

but the architecture team would prefer smaller transfers to avoid hogging the I$/$O bus. Determine

the best transfer size to satisfy all constraints. You may assume that k ranges over values for which

your results make sense and also do not need to use floor and ceiling functions $($so your answer is approximation$)$
