Q1) Suppose that it takes 1 cycle to access and return information on a data-TLB hit and 1 cycle to access and return the information on a data-cache hit. A data-TLB miss takes 300 cycles to resolve, and a data-cache miss takes 100 cycles to resolve. The data-TLB hit rate is 0.99, and the data-cache hit rate is 0.95. What is the average memory access time for a load data reference? Now the data cache is an L1 D-cache and is backed up by an L2 uni?ed cache. Every data reference that misses in L1 has a 60% chance of hitting in L2. A miss in L1 followed by a hit in L2 has a latency of 10 cycles. Compute the average memory access time for load data reference in this new con?guration?
