Consider a non-overlapped memory system that has 1 MB of cache and 8 MB of RAM memories. The cache memory has an access time of 100 ns and a cost parameter of 10-4 $/bit. On the other hand, the RAM memory has an access time of 1200 ns and a cost parameter of 105 $/bit. (a) What is the cost of cache and RAM memories? Which one is the cheapest? (b) If the effective access time is 10% greater than the cache access time. What is the hit ratio H? (c) Suppose that we can change the cache design such that we get H equals to 0.901. Calculate the new effective access time and determine if this change improves the performance or not? Consider a non-overlapped memory system that has 1 MB of cache and 8 MB of RAM memories.
