DMA2D introduction

The Chrom-Art Accelerator™ (DMA2D) is a specialized DMA dedicated to image
manipulation. 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.
All the classical color coding schemes are supported from 4-bit up to 32-bit per pixel with
indexed or direct color mode. The DMA2D has its own dedicated memories for CLUTs (color
look-up tables).
