Average access time experienced by the processor, Computer Engineering

Assignment Help:

Give the formula for the average access time experienced by the processor in a system with 2 levels of caches.

Ans: Formula is for the average access time experienced by the processor in a

system having two levels of caches is described follow:

               tave = h1C1+(1-h1)h2C2+(1-h1)(1-h2)M

h1=> hit rate in the L1 cache

h2= > hit rate in the L2 cache

M=> it's time to access information in the main memory

C1=> it's for time to access information in the L1 cache

 C2=>  it's for time to access information in the L1 cache

Explain Hit and Miss?

Ans. The performance of cache memory is often measured in terms of a quantity is said hit ratio. When the CPU refers to memory and finds the word in cache, it is said hit. If the word is not found in cache, then it is in primary memory and it counts as a miss.
