Computer System question (Memory)

The following questions are about the memory hierarchy. i. Draw a memory hierarchy with one level of cache. (Hint: you should have 4 levels in total). ii. For each adjacent pair of levels in the memory hierarchy, specify whether software (SW) or hardware (HW) manages the data movement between the levels. If both SW and HW are involved, state so explicitly. To answer this question, simply label the arrows between levels of the memory hierarchy in your diagram from part (i) of this question with SW,HW or SW+HW. iii. For each label in part (ii) above, provide a written justification for why HW or SW (or both) should manage data movement
