|
description:
|
|
Chrom-ART Accelerator(DMA2D), graphical hardware accelerator
|
|
enabling enhanced graphical user interface with minimum CPU load
|
|
|
|
It can perform the following operations.
|
|
|
|
- Filling a part or the whole of a destination image with a specific color.
|
|
- Copying a part or the whole of a source image into a part or the whole of
|
|
a destination image.
|
|
- Copying a part or the whole of a source image into a part or the whole of
|
|
a destination image with a pixel format conversion.
|
|
- Blending a part and/or two complete source images with different pixel
|
|
format and copy the result into a part or the whole of a destination image
|
|
with a different color format. (TODO)
