Calculate the hit and miss ratios in the cache and in the main memory for the processor assuming if the processor performs (n) number of total memory references over a period of time. Out of which (m) references are hits in the cache and (K) references of which are hits in the main memory. Also, provide your own reflection when cache (hit and miss) and memory (hit and miss) occur. Note: use own values for n, m, and K.

If memory read cycle takes 100 ns and a cache read cycle takes 20 ns, then for four continuous references, the first one brings the main memory contents to cache and the next three from cache. Find the time taken for the Read cycle with and without Cache? What is the Percentage speedup obtained?
Suppose a byte-addressable computer using set-associative cache has 216 bytes of main memory and a cache of 32 blocks, and each cache block contains 8 bytes.Q.) If this cache is 2-way set associative, what is the format of a memory address as seen by the cache; that is, what are the sizes of the tag, set, and offset fields?
Let's pretend for a moment that we have a byte-addressable computer with 16-bit main memory addresses and 32-bit cache memory blocks, and that it employs two-way set associative mapping. Knowing that each block has eight bytes, please calculate the size of the offset field and provide evidence of your calculations.
