DDR memory is used to store video frame buffers for full configuration mode. The subsystem uses 5 frame buffers for progressive input and 3 field buffers for interlaced input. You can calculate the amount of memory required by the subsystem using the following equations:
5 * MAX_WIDTHp * MAX_HEIGHTp * NUM_VIDEO_COMPONENTS * BytesPerComp
+
3 * MAX_WIDTHi * MAX_HEIGHTi * NUM_VIDEO_COMPONENTS * BytesPerComp
