Question 1 (15 marks) Suppose that the processor has access to two levels of memory. Level 1 contains 1000 words and has an access time of 0.01ms; level 2 contains 100,000 words and has an access time of 0.1ms. Assume that if a word to be accessed is in level 1 , then the processor accesses it directly. If it is in level 2, then the word is first transterred to level 1 and then accessed by the processor. Suppose 95% of the memory accesses are found in level 1 . Ignore the time required for the processor to determine whether the word is in level 1 or level 2 . Find the average time to access a word
