| 9 | description: |
| 10 | Chrom-ART Accelerator(DMA2D), graphical hardware accelerator |
| 11 | enabling enhanced graphical user interface with minimum CPU load |
| 12 | |
| 13 | It can perform the following operations. |
| 14 | |
| 15 | - Filling a part or the whole of a destination image with a specific color. |
| 16 | - Copying a part or the whole of a source image into a part or the whole of |
| 17 | a destination image. |
| 18 | - Copying a part or the whole of a source image into a part or the whole of |
| 19 | a destination image with a pixel format conversion. |
| 20 | - Blending a part and/or two complete source images with different pixel |
| 21 | format and copy the result into a part or the whole of a destination image |
| 22 | with a different color format. (TODO) |
