Consider the computer organization with following specifications: The computer has 1 level cache The average memory access time for a microprocessor is 2.4 clock cycle 1 clock cycle is required to find whether the data is present and valid in the cache or not. If the data is not found in the cache, it needs 80 clock cycles to get it from the off-chip memory. You need to improve the average memory access time by 65% and need to add 2nd level of cache such that: This new 2nd level of cache can be accessed in 6 clock cycles. This new 2nd level cache should not affect 1st level cache access time. If the data is not even found in this 2nd level cache, it should take 80 clock cycles to get it from the off-chip memory. To obtain this improvement in access time, how often must the data be found in this 2nd level cache
