For a data cache with a 92% hit rate and a 2-cycle hit latency, calculate the average memory access latency. Assume that latency to memory and the cache miss penalty together is 124 cycles.

Using the Average Memory Access Latency relation, the AMAT value in the scenario described would be 11.92 ns

Given the Parameters :

The Average - Memory Access Time can be calculated using the relation :

The AMAT = 2 + [(1 - 0.92) × 124]

AMAT = 2 + (0.08 × 124)

AMAT = 2 + 9.92 = 11.92 ns

Therefore, the average memory access latency is 11.92ns.

AMAT is 11.92ns.

Explanation:

Given,

Hit rate = 92%

Hit latency = 2 cycle

Latency to memory + miss penalty = 124 cycles

Average Memory Access Latency = ?

We know,

Average memory-access time (AMAT)  = Hit time + Miss rate x Miss penalty

So,

If hit rate is 92% then the miss rate would be 8%

Thus,

AMAT = 2 + 0.08 X 124

AMAT = 11.92ns

Therefore, AMAT is 11.92ns.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
