Consider a memory system that is composed of one cache and a main memory. The access to the main memory takes 39 ns. Given a clock frequency of 8 GHz, an instruction miss rate of 17%, and data instruction miss rate related to load and store instruction is 9%. Assume that the base CPI of 1 and that the percentage of instructions related to Store and Load is 35%.

Calculate the delay caused by the cache in terms of I (the number of instructions). Answers are displayed to the nearest 2 decimal.

Select one: a. 62.87 I b. 81.12 I c. none of the options d. 162.24 I
