A computer system with a cache memory has an average memory access time of TM 60 ns with a hit ratio of h= 85%. The primary memory access time is T₁-220 ns. What is the cache memory access time, Te? Show the equation & all steps of the computation. For each of the following cache organizations, indicate all their fields with their names and sizes in bits. Assume a main memory size of 4 Gigabytes & a cache memory capacity of 64 Kilobytes of main memory data. Clearly indicate which address bits refer to cache addressing & which bits refer to tag information. Compute the total capacity of the cache memory in bytes.

Answer rating: 100% (QA)

To find the cache memory access time Te we can use the formula for average memory access time with caching Te h Tc 1 h Tp Where Te is the cache memory access time h is the hit ratio 085 in this case T... View the full answer
