2 Cache Memory Explain Speeds System B Assume Access Time Cache Memory 10 N Sec Access Tim Q37113432

2.

a) What is cache memory? Explain how it speedsup the system.
b) Assume the access time for cache memory is 10n-sec, the access time for main memory is 200 n-sec, and the hitratio is 0.85. What is the Effective Access Time (EAT) for a memorysystem with a cache memory?

Solution

(a) Cache memory isa special high speed hardware device. It is a special type of RAMchip. It is way faster than the main memory which is the normal RAMchip. The cache memory is very fast. So, the most used data isstored in the cache memory. So, when we require a
