Patent ID: 6941440

Claim:
A node comprising: at least one agent and an input/output (I/O) circuit coupled to an internal interconnect within the node to communicate between the agent and the I/O circuit, wherein the I/O circuit is configured to communicate on a global interconnect to which one or more other nodes are coupled during use, and wherein an address transmitted on the internal interconnect to access a first resource of the node is to a first local address space of the node, and wherein an address transmitted on the internal interconnect to communicate on the global interconnect is in a global address space; wherein the node is programmed, during use, to map the first local address space to a second local address space, in which the second local address space has a numerical value that does not conflict with resources of other node or nodes that communicate on the global interconnect and to allow the same numerical value for the second local address space and address spaces corresponding to the other node or nodes coupled to the global interconnect to refer to the first resource in the node by use of the numerical value.
