Resolution
(width x height)
(MStar suggests)
Remark
JPEG
Base-line
1920x1080
The limitation of max
resolution depends on
DRAM size (up to
15360x8640).
Progressive
1024x768
The limitation of max
resolution depends on
DRAM size (up to
7000x7000).
PNG
non-interlace
1920x1080
The limitation of max
resolution depends on
DRAM size (up to
15360x8640).
interlace
1920x1080
The limitation of max
resolution depends on
DRAM size (up to
15360x8640).
BMP
15360x8640
The limitation of max
resolution depends on
DRAM size (up to
15360x8640).
• Resolution is a kind of reference design instead of hardware limitation because it is bounded by
DRAM size and performance.
• The larger resolution, the bigger DRAM size
• The larger resolution , the less performance, since it requires longer time to show a picture
• Whether adopting JPEG/PNG hardware or not, decoder can be set. The max resolution of Jpeg
hardware decoder is16360x16360.
• BMP decoder is a software decoder. The limitation of max resolution depends on DRAM size.
