Suppose that a processor has access to three levels of memory. Level 1 contain 2000 words and has an access time of 0.02 msec. Level 2 contain 10,000 words and has an access time of 0.2 msec. Level 3 contains 20,000 words and has an access time of 2 msec. Assume that ifa word to be accessed is in level 1, then processor access it directly.is in level 2 the word is first transferred toL, and then accessed by the processor. Similarly for Ly the word is transferred to La then to L, and then accessed. The hit ratio for level 1 is 0.65 and for level 2 is 0.45. What is the average access time (in ?
