Compute the effective CPI for an implementation of a RISC$-$V CPU using

Figure A$\mathrm{.}29($Page A$-42).$ Assume we have made the following measurements of average CPI

for instruction types:

Instruction Clock cycles

All ALU operations $1\mathrm{.}5$

Loads $4\mathrm{.}5$

Stores $3\mathrm{.}0$

Branches

Taken $5\mathrm{.}0$

Not taken $2\mathrm{.}0$

Jumps $3\mathrm{.}0$

Assume that $60\%$ of the conditional branches are taken. Average the instruction frequencies of

bzip and omnetpp to obtain the instruction mix. Assume that all other instructions require $4\mathrm{.}0$

clock cycles each.
