 Hmm, "the process need update" looks right to me (compare "the process 
need not update") as "need" is used as a modal verb in this sentence.  
Alternatively "the process needs to update" could be used (with "need" as 
a main verb, and "to" then).

 I'm not a native English speaker though, so I might be missing a usage 
subtlety here.

 NB I'd be in favour of capitalising "PTE" and "TLB" consistently 
throughout though as the norm is with acronyms.
