Interconnect and method of managing a snoop filter for an interconnect

摘要: An interconnect and method of managing a snoop filter within such an are provided. The is used to connect plurality devices, including master devices where one or more the has associated cache storage. comprises coherency control circuitry perform operations for data access transactions received by from devices. In performing those operations, that maintains address-dependent caching indication data, responsive transaction specifying target address produce providing which have cached in their then responds issuing each device indicated order cause operation be performed storage generate response data. Analysis determines update condition, upon detection condition triggers performance By subjecting analysis, it possible identify situations become out date, accordingly, this giving rise significant benefits interconnect.
