INTERCONNECT AND METHOD OF OPERATION OF AN INTERCONNECT
Abstract:
An interconnect, and method of operation of an interconnect, are provided for connecting a plurality of master devices and a plurality of slave devices. Hazard management circuitry is used to serialise transactions to overlapping addresses. In addition, gating circuitry ensures 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. Hence, 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.
