发明名称 An interconnect and method of operation of an interconnect
摘要 An interconnect for connecting a plurality of master devices and a plurality of slave devices comprises hazard management circuitry to serialise transactions to overlapping addresses; gating circuitry ensuring ordered write observation (OWO) behaviour at an interface to one or more of the master devices, the gating circuitry receiving write address transfers of write transactions and performing a gating operation to gate onward propagation of the write address transfers to the slave devices in order to ensure the OWO behaviour. The gating circuitry performs the gating operation under control of the hazard management circuitry. The interconnect may further comprise deadlock avoidance circuitry to gate onward propagation of write address transfers of write transactions. The benefit for this interconnect is that, for write transactions that are subjected to hazard checking by the hazard management circuitry, this removes the need to implement any other processes to specifically manage OWO behaviour for those write transactions.
