Patent ID: 7554355

Claim:
A crossbar switch architecture comprising: 2×1 multiplexers connected in at least a 2×2 matrix form consisting of rows and columns, wherein the 2×1 multiplexers each have one input line connected with an output line of a multiplexer at a front column of the same row, the other input line connected with an input/output line of a column including the corresponding multiplexer wherein the input/output line of the column including the corresponding multiplexer is connected to an input of each 2×1 multiplexer of the column including the corresponding multiplexer, and an output line of a multiplexer at the last column of each row is connected with an input/output line of the row, wherein input/output lines of the rows are respectively connected with output lines of one slave-group multiplexer, and input lines of the slave-group multiplexer are respectively connected with slaves.
