A company that designs scientific computers is considering using the MIPS architecture for a processor that will go into mid$-$range scientific and engineering workstations. The applications that users typically run on these machines have the following instruction distribution and average CPI$$s:

Instruction Percentage Average CPI

Load$/$Store $40\%1\mathrm{.}4$

Integer ALU $25\%1\mathrm{.}0$

Integer Multiply $10\%2\mathrm{.}0$

FP Multiply $5\%4\mathrm{.}0$

FP Add $10\%2\mathrm{.}5$

Branch $10\%1\mathrm{.}5$
