a) Suppose a computer having 5 GHz processor with cycle time of 2ns and main memory access time
100ns with CPI is 2 cycle.
i. Calculate the processor performance without cache.
ii. Calculate the performance with L1 cache, assume L1 hit rate is 75% and access time is 1ns.
iii. Calculate the performance with L2 cache, assume L2 hit rate is 90% and access time is 5ns.
iv. Calculate the performance with L3 cache, assume L3 hit rate is 95% and access time is 7ns.
c) It is desired to have memory of 64Kbytes given that a 13 bit address bus is used to address
memory location. Design the decoding architecture in order to access complete 64Kbytes
memory also calculates address ranges for each memory chip.
