Assume an memory hierarchy with unified data and instruction memories, miss rate equal to 15%, miss penalty equal to 90 cycles, 25% Load/Store instructions, TLB miss ratio per TLB access equal to 6% and TLB miss penalty equal to 80 cycles. What is the realistic CPI of this system if the ideal CPI is 1.5? What is the speedup compared to not having TLB? What would be the speedup if the TLB could hold every entry?
