Select the option that is correct about memory systems and cache organizations:

Group of answer choices

Set$-$associative cache has a higher hardware complexity for cache search compared to other cache organization techniques. However, it is the most effective technique in terms of performance and speed, providing the highest cache hit rate among different cache organizations regardless of the target application domain.

In an $8-$way set associative cache, the hardware to generate the cache hit control signal includes $8$ Comparators, $16$ AND gates, and $1$ OR gate.

Set$-$associative cache organization allows multiple cache blocks to be stored in each set.

To optimize the memory hierarchy, small cache size, low associativity, and high block size would result in the best performance.
