Abstract
Provided is a crossbar switch architecture appropriate to a multi-processor system-on-a-chip (SoC) platform including a plurality of masters and slaves, capable of high-speed data transfer, allowing the number of masters or slaves therein to be easily increased, and having a simple control structure. The crossbar switch architecture includes 2×1 multiplexers connected in a matrix form consisting of rows and columns. 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, and the other input line connected with an input/output line of a 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.
