This Figure shows an example of zooming a video frame. It assumes that the video frame is read from external memory and written back to external memory. This allows for a slower minimum operating clock frequency and a lower bandwidth requirement.
In the example in This Figure , Table: Zoom Mem-to-Mem Example Minimum Bandwidth and Frequency Requirements shows the input and output minimum frequency and minimum bandwidth requirements, assuming a data width of 16 and a 60 frames-per-second frame rate.
