6.12.1. Avalon® Streaming Crossbar

Each 4x4 Avalon® Streaming crossbar unit consists of four, 1x4 demultiplexers, and four 4x1 multiplexers. When full connectivity is enabled, TDEST routes signals through the multi-hop crossbar by passing on the TDEST signal to Avalon® Streaming IPs in the form of an Avalon® Streaming channel. Avalon® Streaming multiplexers use round-robin arbitration to determine routing in case of conflict.
