Assume thаt fоr а given prоgrаm 70% оf the executed instructions are arithmetic, 10% are load/store, and 20% are branch. Given this instruction mix and the assumption that an arithmetic instruction requires 2 cycles, a load/store instruction takes 6 cycles, and a branch instruction takes 3 cycles, find the average CPI. (explain the computation steps)   hint: to compute the average CPI just compute the weighted average i.e. sum of products of percentage and cycles of the individual operations
