Abstract
A data processing system comprises a master node to initiate data transmissions; one or more slave nodes to receive the data transmissions; and a home node to control coherency amongst data stored by the data processing system; in which at least one data transmission from the master node to one of the one or more slave nodes bypasses the home node.
Claims9
Interface circuitry comprising:
- circuitry to exchange information with a master node of a data processing system and with a home node and one or more slave nodes, the home node controlling coherency amongst data stored by the data processing system;
- the interface circuitry being configured to receive a transmission request and a data transmission from the master node according to a first data transfer protocol and to transfer data from the received data transmission to a given slave node according to a second, different, data transfer protocol.
A method comprising:
- providing interface circuitry to exchange information with a master node of a data processing system and with a home node and one or more slave nodes, the home node controlling coherency amongst data stored by the data processing system;
- the interface circuitry receiving a transmission request and a data transmission from the master node according to a first data transfer protocol and transferring data from the received data transmission to a given slave node according to a second, different, data transfer protocol.
