Chroma Resampler XAPP932 - Are the HSYNC and VSYNC signals necessary?

Description

Are the HSYNC and VSYNC signals necessary?

Solution

Yes, the Chroma Resampler example design is written with the expectation that you are going to be feeding in live video, and uses the HSYNC and VSYNC signals.

If a user is reading from a memory, they can use one of the following options:

  • Create a simple circuit to generate the HSYNC and VSYNC signals
  • Use the Video Timing Controller core to generate the HSYNC and VSYNC signals
  • The source code is provided and can be modified to meet the design requirements
