Abstract
The management of transactions received by a coherency controller is disclosed. A method of an embodiment of the invention is performed by a coherency controller of a plurality of coherency controllers of a node that has a plurality of sub-nodes. The coherency controller receives a transaction from one of the sub-nodes of the node. The transaction may relate to another sub-node of the node. However, the coherency controller nevertheless processes the transaction without having to send the transaction to another coherency controller of the node, even though the sub-node from which the transaction was received is different than the sub-node to which the transaction relates. The plurality of coherency controllers is thus shared by all of the plurality of sub-nodes of the node.
