WebA CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.Most CPUs have a hierarchy of … WebReduce Misses via Larger Block Size l 16K cache, miss penalty for 16-byte block = 42, 32-byte is 44, 64-byte is 48.

Generate the data for caches capacity from 256 bytes (2 8) to 4MB (2 22 ). Configure the block size to 64 bytes. Below are the first two commands you should run. The first sets the cache capacity to 2 8 = 256 bytes and the block size to 2 6 = 64 bytes.
