Expert Solution
Step 1

Between the L1 and L2 cache, buffers are required.

The buffer required between the L1 cache and the L2 cache is the write buffer.

The purpose of this write buffer is to decrease access latency.

If there is a miss on the L1 cache, the data may be retrieved via the L2 cache.
