The Translation Lookaside Buffer
Captions available
The idea
The translation lookaside buffer caches recent address translations inside the CPU — a hit forms the real address at once; a miss consults the page table; an absent page faults.
In practice
A courier's memorized addresses beat the office lookup on every repeated street.
Where people slip
Hit, miss, and fault are three different prices.
