d) Suppose we have a processor with a clock rate of 4 GHz. Assume a main memory access time of 100 ns primary cache is(2%) How 0.5%2 Show your work to get full credit. ncluding all the miss handling. Suppose access time for primary cache is I cycle and the miss rate at th much faster will the processor be if we add a secondary cache that has a4z access time for either a hit or a miss and is large enough to reduce the global miss rate to main memory t (8
