1. A method in a processor of performing an address match check, said method comprising: performing a partial match check including comparing a first set of bits contained in the requested address to a second set of bits contained in a registry address, wherein the registry address is stored in an address registry; performing a full match check if the first set of hits matches the second set of bits; storing a result of the partial match check; allowing a set of instructions requesting the requested address to continue execution only if the first set of bits does not exactly match the second set of bits; and transmitting a reject signal only if the first set of bits matches the second set of bits, wherein the reject signal is operable to cause a set of instructions requesting the requested address to suspend execution.
