Re: Mapping
Just wanted to know what is the concept of TLB in HPUX and what a TLB cache miss/hit was. Is the TLB a finite registry? Can someone briefly throw some light on to this!

Re: Mapping
The TLB is a hardware thingy. A web search should tell you about those. Yes, the TLB is very limited and the OS has to constantly refill it. Large pages help here.
There are both a hardware and software walkers to handle misses.
>TLB cache miss/hit
As in any cache, if you get a hit, it's fast, if you get a miss, something has to flush a cache entry and refill it with the new info.
