摘要： A method and apparatus for improving snooping performance is disclosed. In one embodiment, one or more content addressable matches are used to determine where and when an address conflict occurs. Depending upon the timing, a read request or a snoop request may be set for retry. In another embodiment, an age order matrix may be used to determine when several core snoop requests may be issued during a same time period, so that the snoops may be processed during this time period.

摘要： Preventing request conflicts within microprocessors and/or computer systems. More particularly, embodiments of the invention relate to a technique to manage request conflicts within a processor and/or computer system in which a number of accesses may be made to a particular cache or group of caches shared amongst a set of cores or processors or agents.
