Note: This is in terms of ARM architecture. A computer has a level 1 cache with an access time of 2 cycles and an average hit rate of 90% andDRAM access time is 100 cycles.a. What is the average memory access time for this computer? Ans:cycles(Give answer with two precision format, e.g. 1.23)b. If the system is upgraded with a level 2 cache with a hit ratio of 85% and an access time of 10cycles. What is the new average memory access time for this computer?Ans:cycles(Give answer with two precision format, e.g. 1.23)c. If the system is further upgraded with a level 3 cache with a hit ratio of 80% and an access time of50 cycles. What is the new average memory access time for this computer?Ans:cycles(Give answer with two precision format, e.g. 1.23)d. What is Speed up in performance achieved with the addition of L2 cache?Ans:(Give answer with two precision format, round off to the nearest digit e.g. 1.236=1.24)e. What is Speed up in performance achieved with the addition of L3 cache?Ans:(Give answer with two precision format, round off to the nearest digit e.g. 1.236=1.24)Note: Addition of L2 and L3 cache has no impact on access time for DRAM.
