The Mill, if it ever gets built, does something like that. http://millcomputing.com/wiki/Memory#Implicit_Zero_and_Virtu... "The big gain for this is that the OS doesn't have to explicitly zero out new pages, which would be a lot of bandwidth and time, and accesses to uninitialized memory only take the time of the cache and TLB lookups instead of having to do memory round trips." |
