Abstract:
An apparatus for distributing a signal from a signal source to a plurality of destination nodes, the apparatus comprising:an array of bus nodes having at least three rows and three columns of bus nodes, each bus node corresponding to a separate one of said plurality of destination nodes, each row of bus nodes including at least three bus nodes, and each column of said bus nodes including at least three bus nodes; a plurality of first daisy-chain buses, one for each of said rows of bus nodes, each first daisy-chain bus linking all bus nodes of a separate one of said rows of bus nodes, and each first daisy-chain bus having two ends; at least one second daisy-chain bus, each corresponding to a separate one of said columns of bus nodes and linking all bus nodes of the corresponding one of said columns of bus nodes; a plurality of conductors, each connected near said ends of said first daisy-chain buses, such that each first daisy-chain bus is linked to at least one other of said first daisy-chain buses, and such that said conductors and said first and second daisy-chain buses form a closed-grid bus conductively interconnecting all of said bus nodes of said array of bus nodes; first means for conductively linking said closed-grid bus to said signal source; and second means for conductively linking each of said bus nodes to its corresponding destination node.
