Patent ID: 7484052

Claim:
A method for handling address concentrator (AC) functions in a multi-processor system containing a plurality of independent nodes, wherein each node is associated with one processor in said system and includes a logic block capable of performing the address concentrator function, and each AC logic block has an address assigned to it for address concentration comprising: arranging the processors in a closed loop; assigning each node with a separate address range for data storage; distributing AC command traffic approximately equally among each of the nodes; when a processor issues a command to a node, the AC logic block at that node determines if the address range for said command is in the range assigned to that AC logic block for address concentration function; if yes, the AC logic block performs the AC function and, if no, the command is passed to the next node in the loop for said determination; the determination is made successively from one node to the next in the loop until the range of addresses for address concentration is found and the AC function performed at that node; whichever AC logic block performs the AC function will start reflecting commands and building a combined response which is delivered sequentially to each successive node in the loop.
