Abstract: Circuitry comprises attribute storage circuitry having a plurality of entries to hold data defining at least a transaction attribute of one or more respective data handling transactions initiated by transaction source circuitry; comparator circuitry to compare a transaction attribute of a given data handling transaction with data held by the attribute storage circuitry to detect whether the given data handling transaction would be resolved by any data handling transaction for which attribute data is held by a respective entry in the attribute storage circuitry; and control circuitry to associate the given data handling transaction with the respective entry in the attribute storage circuitry to form a set of associated data handling transactions when the comparator circuitry detects that the given data handling transaction would be fulfilled by the data handling transaction for which attribute data is held by the respective entry in the attribute storage circuitry; the control circuitry comprising output circuitry responsive to a resolution of a data handling transaction in the set of associated data handling transactions, to provide that resolution to the transaction source circuitry as a resolution of each of the set of associated transactions.
