DDR memory is used to store video frame buffers for full configuration mode. The subsystem uses five frame buffers for progressive input and three 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

and

3 * MAX_WIDTHi * MAX_HEIGHTi * NUM_VIDEO_COMPONENTS * BytesPerComp

BytesPerComp
  • 1 Byte for 8 bit data
  • 2 Byte for 10/12/16 bit data
