Per memory layer, there is a memory mapped AXI4 interface named m_axi_mm_video i with i representing the layer number minus 1. The memory mapped AXI4 interface runs on the ap_clk clock domain. The signals follow the specification as defined in the Vivado Design Suite: AXI Reference Guide (UG1037) [Ref 1] . Table: Pixel Formats shows the pixel formats in memory supported by the Video Mixer.
