in a $8$ stage pipleine register.For a program$-8,20\%$ instructions are branches dependent on an integer arithmetic instruction just preceding them and $5\%$ are branches not dependent on a preceding Instruction. Of all branches, $70\%$ are taken branches. Branch condition is evaluated in the EX$-$stage and branch target address is computed in the ID$-$stage. Again, assuming no forwarding paths are available, compute the addition to the CPI due to these hazards. What types of hazards are present here?
