The Video In to AXI-4 Stream LogiCORE™ IP core converts common parallel video signals (such as from a DVI PHY) to an AXI4-Stream interface. The input video signals must have data, clock, DE, sync signals (Vsync and Hsync) and/or blanking signals (Vblank and Hblank). The AXI4-St...
When you want to generate an AXI4-Stream interface in your IP core, in your DUT interface, implement these signals: Data Valid Optionally, when you map scalar DUT ports to an AXI4-Stream interface, you can model these signals: Ready Other protocol signals, such as: TSRTB TKEEP TLAST ...

With AXI4-Stream IP core generation, you can optionally model other streaming control signals. For example, you can model the back pressure signal, Ready. The AXI4-Stream interface communicates in master/slave mode, where the master device sends data to the slave device. The Ready...
The AXI4-stream protocol shares a similar set of flow-control signals to our own valid-ready data streaming protocol. For this reason, it is very easy to adapt our IP-Cores to the AXI4 specification. In addition, we can also provide versions of our IP to support other streaming protocols...
