Consider a memory system with the following parameters: Tc = 100 ns Cc = 10-4 $/bit Tm

Question:

Consider a memory system with the following parameters:
Tc = 100 ns Cc = 10-4 $/bit
Tm = 1200 ns Cm = 10-5 $/bit
a. What is the cost of 1 Mbyte of main memory?
b. What is the cost of 1 Mbyte of main memory using cache memory technology?
c. If the effective access time is 10% greater than the cache access time, what is the hit ratio H?
