The Warp Filter must be configured correctly to operate properly. There should be sufficient memory bandwidth available for this core to function properly. The bandwidth needed (in MB/s) for a memory layer can be calculated with the following equation:
Where, 'fps' is the number of frames per second the IP is operating, 'height' is the height in lines of the image, and 'stride' is the stride in bytes of the image.
For example for a 3840x2160@60 RGB 12-bit video, the bandwidth requirement is calculated as follows:
S = 60 x 2160 x 3840 x 5
D = 60 x 2160 x 3840 x 5
R = 60 x 2160 x 3840 x 4
Total bandwidth required = ~7 GB/s
