4.1. AXI Stream Bridge
This bridge is responsible for converting the AXI-ST Data of the user interface to the AVST data interface of the underlying IP modules, and vice versa. The AVST interface supports both SOP aligned and MAC segmented Client Interfaces while the AXI-ST interface supports both Single and Multi Packet Modes. The bridge also supports single MAC segmented interface converted to multiple streams of AXI-ST Single packet mode and vice versa.
The AXI bridge is responsible for converting between these interfaces based on the table below.
Speed | AVST Data Width | AVST | Freq(MHz) | AXI-ST Data Width | AXI Packet Mode | Freq(MHz) | Number of Streams |
---|---|---|---|---|---|---|---|
10G | 64 | SOP | 161.13 | 64 | Single | 415.03 | 1 |

Note: When Enable System PLL for F-Tile parameter is enabled, the F-Tile system PLL IP is integrated into the Ethernet Subsystem IP and configured to 830.07MHz. Additionally, the AXI-ST clocks will be configured to 415.03MHz for all Ethernet speeds from 10GE to 400GE.
2 The highlighted configurations are supported through multi stream mode, which converts a single MAC segmented interface into multiple streams of lower data width buses.
