Consider a version of the pipeline from Section $4\mathrm{.}6$ that does not handle data hazards $($i$.$e$.,$ the programmer is responsible for addressing data hazards by inserting NOP instructions where necessary$).$ Suppose that $($after optimization$)$ a typical n$-$instruction requires an additional $4*$n NOP instructions to correctly handle data hazards.

$[10]<4\mathrm{.}6>$ Different programs will require different amounts of NOPs. How many NOPs $($as a percentage of code instructions$)$ can remain m the typical program before that program runs slower on the pipeline with forwarding.
