White Rabbit Switch - Gateware
This project concerns the internals of the WR Switch HDL design. It contains numerous modules connected with the Wishbone Crossbar. Each of them has a Wishbone Slave interface and a number of configuration registers that are read/written from main CPU through the CPU EBI/WB bridge (WB Master interface). Blue arrows in the figure represent the WR Frabric interface connections responsible for passing Ethernet frames between the Endpoints, Switching Core and Network Interface Controller.
