On-chip interconnection networks simplify the integration of complex system-on-chips. The switches are the basic building blocks of such networks and their design critically affects the performance of the whole system. The transfer of data between the inputs and the outputs of the switch is performed by the crossbar, whose active connections are decided by the arbiter. In this paper, we design scalable dynamic-priority arbiters that are merged with the crossbar's multiplexers. The proposed RTL

With this approach, sophisticated arbitration policies that yield significant networkthroughput benefits can be implemented with negligible delay cost relative to the standard round-robin policy.
