The CPU design team is designing an instruction set with three classes of instructions.

Parameters are given in the following table. Consider a program with $70\%$ ALU instructions, $20\%$

memory access instructions, and $10\%$ control instructions. What is the average CPI for this CPU?

Clock Rate$=2$GHz

CPI for ALU Inst.$=3$

CPI for Memory Inst.$=6$

CPI for Control Inst.$=1$
