Consider a $5-$stage integer pipeline with forwarding. Assume the branch penalty is $1$ cycle $($branch condition computed in ID$).$ Now assume we have pipelined the memory system to three stages $($rather than $1$ stage$)$ for both instruction fetch and data fetch. Branches are resolved at the end of the EX stage. We use a static branch$-$taken prediction strategy, i$.$e$.,$ if branches are not$-$taken we incur the branch penalty. Assume conditional branches occur with a frequency of $25\%.$ If branches are taken $35\%$ of the time, what is the increase in CPI due to this prediction strategy?
