- The caches are valuable for two reasons: how do they address the problem? Are they causing any problems? So, if it's possible to create a cache that's the same size as the device it's caching for (for example, a disk cache), why not do that, and remove the device?Aside Cache lines, sets, and blocks: What's the difference?Design a Cache memory for your Project for a direct-mapped cachewith 1MB of data .• Design a Cache memory for your Project for a direct-mapped cachewith 64KB of data .Assume n-word block size, assuming a N-bitaddress? N=19 n=5
- There are a few different reasons why caches are useful. What exactly is the point of all of their hard work? What are the repercussions of making use of them? Why not simply make the cache the same size as the device it is caching, in the event of a cache (for example, a whole hard drive)?The caches are valuable for two reasons: Why do they exist? How do they affect the environment? The question is, if a cache can be made as big as the device it caches (for example, a disk cache), why not make it that huge and remove the device?. For an 8-wordwide cache with the following access times, calculate the effective bandwidth. L1: 2 bus cycles,L2: 100 bus cycles Detailed answer please. Thank you

Start and stop. How many interrupts will occur for the data transfer? 3-What are the two commands that will be issued by the supervisor for each interrupt?OPERATING SYSTEMS Give two reasons why caches are useful.What problems do they solve?What problems do they cause? If a cache can be made as large as the device for which it is caching (for instance, a cache as large as a disk),why not make it that large and eliminate the device?
