Consider the following sequence of page address requests generated by a two-level virtual memory system with a main memory capacity of 3 pages (i. e. page 1 is requested, then page 2, ) Show the memory contents after each request and compute the hit ratio using the first-in-first-out (fifo) and least recently used (lru) replacement policies. A computer has a first-level on-chip cache, and a second-level off-chip cache. During the execution of a program, 1000 instructions are fetched from the memory system. The hit ratio for the l1 cache is.
