This Figure illustrates example timing on the S2MM channel for Vertical Size = 5 lines, Horizontal Size = 16, bytes, and Stride = 32 bytes. The figure shows the m_axi_s2mm and s_axis_s2mm interfaces.
Dataflow: After the reception of s2mm_fsync, AXI VDMA drives s2mm_fsync_out and s_axis_s2mm_tready to indicate its readiness to receive a frame on the streaming interface. Incoming streaming data is stored in the line buffer and driven onto the mm side by asserting m_axi_s2mm_awvalid and subsequently driving data on m_axi_s2mm_wdata along with m_axi_s2mm_wvalid.
