There are four Genlock options:
•Master
When selected, outputs the current frame number on the mm2s_frame_ptr_out port.
•Slave
When selected, Slave follows the Master by the frames set in the Frame Delay register either by skipping or repeating frames. GenlockEn (MM2S_VDMACR[3]=1) register should be set to enable genlock synchronization between Master and Slave. It outputs the current frame number on the s2mm_frame_ptr_out port.
•Dynamic Master
When selected, AXI VDMA skips the frame buffers that the Dynamic Slave is working on. It outputs the completed frame number on the mm2s_frame_ptr_out port.
GenlockEn (MM2S_VDMACR[3]=1) register should be set to enable genlock synchronization between Dynamic Master and Dynamic Slave.
•Dynamic Slave
When selected, AXI VDMA follows the Dynamic Master either by skipping or repeating frames. It outputs the current frame number on the mm2s_frame_ptr_out port.
GenlockEn (MM2S_VDMACR[3]=1) register should be set to enable genlock synchronization between Dynamic Master and Dynamic Slave.
