Hi sneha22,

I understand your system is working fine as-is but I do not think the SOPC Builder fabric can preserve Avalon-MM bursts through the clock-crossing adapter. Memory accesses may be quite inefficient and you may have trouble while expanding the design in the future.

The frame buffer already comes with dual-clock FIFOs and you just need to enable them in the GUI.

Before you try adding more components, you should make sure that you can configure the CVO properly for the output resolution you are targetting. You may use the test pattern generator IP for that purpose.
