(15pt) Assume that instruction cache miss rate is 2%, data cache miss rate is 10%, CPI (clock cycle per instruction) is 2 without any memory stall, and miss penalty is 100 cycles. In addition, assume that the frequency of loads/stores is 30%. (a) Compute CPI with memory stall. (b) When CPI without any memory stall becomes 1, compute CPI with memory stall. (c) If the CPU clock rate is doubled with the same memory when CPI without memory stall is 2, compute CPI with memory stall.
