$3.$ Compute the effective CPI for RISC$-$V using Figure A$\mathrm{.}29$ and the table below that shows cycles for different instruction types. Average the instruction frequencies for all benchmarks to obtain the instruction mix. Assume that branches are taken $60\%$ of the time $($and not taken $40\%$ of the time$).$ You may assume that all other instructions $($for instructions not accounted for by the types in Table A$\mathrm{.}29)$ require $3\mathrm{.}0$ clock cycles each.
