10.2.6. DMA Support
The DMA interface (DMA_EXTRA) is disabled by default. It must be enabled in the IP to have the additional DMA_Handshaking_tx and DMA_Handshaking_rx interfaces. DMA support is only available when used with the HPS DMA controller. The HPS DMA controller has the required handshake signals to control DMA data transfers with the IP through the DMA_Handshaking_tx and DMA_Handshaking_rx interfaces. The DMA handshaking interfaces are connected to the HPS through the f2h DMA request lines.
For more information about the HPS DMA Controller handshake signals, refer to the DMA Controller chapter in the Cyclone® V Device Handbook, Volume 3.
