Consider our initial pipelined MIPS machine which has $5$ pipestages:

$($IF ID EX MEM WB$)$ Assume that for a conditional branch instruction,

the target address is computed in the second stage $($ID stage$)$ and the

branch outcome $($i$.$e$.,$ branch decision$)$ is determined in the fourth

stage $($MEM stage$).$ Assume that $30\%$ of all instructions are

conditional branches and that $75\%$ of these are taken. Assume an

ideal CPI of $1.$ We want to study the effect of various techniques used

for reducing the pipeline branch penalties. Ignore all other types of

hazards.
