Q1. Explain TLB Reach.
Ans.The TLB reach refers to the amount of memory accessible from the TLB and is simply the number of entries multiplied by the page size.
TLB Reach = Number of entries X Page Size
Ideally, the working set for a process is stored in the TLB. If not, the process will spend a considerable amount of time resolving memory references in the page table rather than the TLB. If we double the number of entries in the TLB, we double the TLB reach.
