Abstract:
A method of setting an isochronous transaction in a bus network in which a plurality of buses are connected via a bridge including first communication means and second communication means, comprising:a first step of setting an isochronous transaction for a first bus of the bus network by a resource-possessing node when a sending node or a receiving node exists on the first bus and on which the resource-possessing node also exists, sending a request for setting the isochronous transaction by the resource-possessing node to the first communication means of the bridge existing on the first bus when no sending node or no receiving node exists on the first bus, and passing a packet to the sending node or the receiving node not existing on the first bus; a second step of sending a request for setting the isochronous transaction to the second communication means connected to the first communication means by the first communication means which receives the request for setting an isochronous transaction from the resource-possessing node, and setting the isochronous transaction for the first communication means when the first communication means exists on a path from the sending node to the receiving node; and a third step of setting the isochronous transaction for a second bus, when the sending node or the receiving node exists on the second bus on which the second communication means exists, by the second communication means which receives the request for setting the isochronous transaction, setting isochronous transaction for the second communication means when the second communication means exists on a path from the sending node to the receiving node, and sending a request for setting the isochronous transaction to the first communication means of the bridge existing on the second bus when no sending node or no receiving node exists on the second bus and passing a packet to the sending node or the receiving node not existing on the second bus.
