A method of performing a fast information compare within a processor which
includes performing a more significant bit compare when information is
loaded into a translation lookaside buffer, storing a result of the more
significant bit compare within the translation lookaside buffer as part
of an entry containing the information, and using the result of the more
significant bit compare in conjunction with results from a compare of
less significant bits of the information and less significant bits of
compare information to determine whether a match is present. The more
significant bit compare compares more significant bits of the information
being loaded into the translation lookaside buffer with more significant
bits of compare information.
