Abstract
An interconnect has transaction tracking circuitry for enforcing ordering of a set of data access transactions so that they are issued to slave devices in an order in which they are received from master devices. The transaction tracking circuitry is reused for also enforcing ordering of snoop transactions which are triggered by the set of data access transactions, for snooping master devices identified by a snoop filter as holding cache data for the target address of the transactions.
