The AXI VDMA core supports the following three sources for frame synchronization.
•AXI4-Stream based frame synchronization using the tuser(0) port
°Drives the start-of-frame on the m_axis_mm2s_tuser(0) output for read path
°Synchronizes the incoming frame with the start-of-frame on the s_axis_s2mm_tuser(0) input for write path
•Streaming to Memory Mapped frame sync port (s2mm_fsync)
•Memory Mapped to Streaming frame sync port (mm2s_fsync)
