More Information
Summary:In a data processing network comprising one or more Request Nodes and a Home Node coupled via a coherent interconnect, a Request Node requests data from the Home Node. The requested data is sent, via the interconnect, to the Request Node in a plurality of data beats, where a first data beat of the plurality of data beats is received at a first time and a last data beat is received at a second time. Responsive to receiving the first data beat, the Request Node sends an acknowledgement message to the Home Node. Upon receipt of the acknowledgement message, the Home Node frees resources allocated to the read transaction. In addition, the Home Node is configured to allow snoop requests for the data to the Request Node to be sent to the Request Node before all beats of the requested data have been received by the Request Node.
