Consider a memory system that is composed of one cache and a main memory. The access to the main memory takes 18 ns. Given a clock frequency of 4 GHz, an instruction miss rate of 14%, and data instruction miss rate related to load and store instruction is 14%. Assume that the base CPI of 1 and that the percentage of instructions related to Store and Load is 27%.

Calculate the CPI for the system taking into consideration the delay caused by the memory system. Answers are displayed to the nearest 2 decimal.
