Abstract:
A method of data transfer among a plurality of nodes comprising the steps of:initializing transfer operations from a master node, said initializing including generating a read command including an indication of one of the plurality of nodes and a memory address; disposing the plurality of nodes in closed loop having a first node and a last node; passing a received read command including said indication of one of the plurality of nodes and said memory address from each node to a next node in said closed loop, the first node of the plurality of nodes receiving said read command generated by the master node; and determining at each node whether a read command including said indication of one of the plurality of nodes and said memory address received from a prior node includes an indication of one of the plurality of nodes corresponding to that node, if so reading data from a memory at an address corresponding to said memory address of said read command and passing said read data to said next node in said closed loop, the last node of said plurality of nodes passing said read data to the master node.
