<p>PROBLEM TO BE SOLVED: To mount nodes without the existing multi-dividing functions, to perform efficient node coupling even when a few nodes are mounted and to further make a multi-node system abundant in extensibility in the multi-node system having the multi-dividing function. SOLUTION: Node coupling devices are prepared one for each node and a transaction controller of the node coupling device is constituted so that it has a division control register for holding pieces of division information (a group ID, memory mapping information, I/O mapping) information between nodes corresponding to the respective ports. And the transaction controller calculates the node to be a destination of transaction by the division information corresponding to the port where the transaction comes by referring to the division control register and transmits the transaction to the destination.</p> |
