What is Understanding Translation Lookaside Buffer about?

The Translation Lookaside Buffer (TLB) caches the most recent page table entries to map linear to physical addresses, allowing the CPU to access data and code without the slow two-stage translation process. It matches the upper 20 bits of the linear address to see if the physical page address is already cached. If not, it must fetch the page table entry from memory to complete the translation. Larger TLBs like in the Pentium can improve performance by caching mappings for more pages.
