Question
![Most memory systems contain both a translation lookaside buffer (TLB) used by the virtual memory
system, and a cache memory. Both the cache and the TLB have similar functions: they store main
memory data in a faster "cache-like" memory that can be accessed at nearly processor speeds.
The question is why do these two separate mechanisms exist when they have such a similar
purpose? Why have both a cache and a TLB? Why not just a single "supercache" that would hold
both regular memory data as well as frequently used page table entries?
a) What is different about these two fast memories?
b) How are they used in the memory system? (](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F80b1769f-7b18-43b4-8d24-758686163298%2F429e1ae7-aad6-45fc-872f-4b3fe6457e00%2Fehhek0j_processed.jpeg&w=3840&q=75)
