new device for scaling, blending, color fill and color space
conversion on EXYNOS5 SoCs.
This device supports the following as key features.
input image format
- YCbCr420 2P(UV/VU), 3P
- YCbCr422 1P(YUYV/UYVY/YVYU), 2P(UV,VU), 3P
- YCbCr444 2P(UV,VU), 3P
- RGB565, ARGB1555, ARGB4444, ARGB8888, RGBA8888
- Pre-multiplexed ARGB8888, L8A8 and L8
output image format
- YCbCr420 2P(UV/VU), 3P
- YCbCr422 1P(YUYV/UYVY/YVYU), 2P(UV,VU), 3P
- YCbCr444 2P(UV,VU), 3P
- RGB565, ARGB1555, ARGB4444, ARGB8888, RGBA8888
- Pre-multiplexed ARGB8888
input rotation
- 0/90/180/270 degree, X/Y/XY Flip
scale ratio
- 1/4 scale down to 16 scale up
color space conversion
- RGB to YUV / YUV to RGB
Size
- Input : 16x16 to 8192x8192
- Output: 4x4 to 8192x8192
