The Full Fledged configuration has the following memory bandwidth requirements:
- The deinterlacer writes one field and reads two fields. For example,
the memory bandwidth required by the deinterlacer for a resolution of 1080i of 8-bit
RGB data at 60 fps is:
write 1 field = 1920 columns * 540 rows * 4 Bytes * 60 fps = 237 MBytes/second
read 2 fields = 1920 columns * (2*540) rows * 4 Bytes * 60 fps = 475 MBytes/second
- The VDMA writes one frame and reads one frame. For example, the
memory bandwidth required by VDMA for 4K resolution of 8 bit RGB data at 60 fps
is:
write 1 frame = 3840 columns * 2160 rows * 3 Bytes * 60 fps = 1424 MBytes/second
read 1 frame = 3840 columns * 2160 rows * 3 Bytes * 60 fps = 1424 MBytes/second
