Can I use video mixer and HDMI transmitter logiCORE IP without the processor in ZCU104 for combined video display?

I have own RTL code to stream the video(hsync, Vsync and video data) for a particular resolution.

Hi @prasanna_18 ,

Just to correct a bit what @krishnagaihre  said.

For the HDMI TX Subsystem IP, it only supports using the drivers APIs. You might be able to make it work without a processor (with some logic) but as it is a very interrupt driven IP it would be more trouble than just implementing a microblaze processor to control it.

If you are planning for Streaming design then you dont need the Processing System, but if you are doing the memory mapped [using VDMA or AXI Slave IP's] then PS will be needed.
For the Streaming design, you can only have the ".bit" file so no need the VIVADO SDK programming [".elf"] file.
According to PG243, video mixer v3.0 can work on Streaming mode, so your design dont need the PS.
P.S If you use the PS then you can easily make bootable systems, so you can boot from SD card.
