ABSTRACT:
In a system having a plurality of snooping masters coupled to a Bus Macro, a snoop filtering device and method are provided in at least one of the plurality of snooping masters. The snoop filtering device and method parse a snoop request issued by one of the plurality of snooping masters and return an Immediate Response if parsing indicates the requested data cannot possibly be contained in a responding snooping master. If parsing indicates otherwise the at least one plurality of snoop masters searches its resources and returns the requested data if marked updated.
