8.2.2 Remapping
8.2.3 Block Fills
8.2.4 Packed Memory Transfer
8.3 Line Draws
The Graphics Accelerator supports single bit pixel remapping with foreground/background or
foreground/transparency to system color depth images (1 bpp mapped to 4, 8, 16 or 24 bpp
expansion.) Images stored as a single bit plane can be expanded with a foreground color and
either transparent or background color. Remapping can be used for fast transfer of text,
single color patterns, and single color bit maps to video memory.
The Graphics Accelerator supports pixel addressed Block Fills and Block Copies with 4, 8,
16, or 24 bpp resolution. During Block Fills, rectangular blocks of pixels are replaced with the
pixel value that is in the
set to 0x00.
A packed source means that all bits in a word are used for the source image. The only
exception is the last word, which is not required to be used if the image size does not require
the storage. A packed source DOES NOT mean that all words are packed together. The lines
may have none, or one or more word(s) between each line. A line is defined as a continuous
block of words that contains pixel data.
In packed mode, the source can have a different layout than the destination. This is different
from non-packed mode where the

The Graphics Engine supports two types of hardware accelerated lines draws:
The only programming difference between the two line draw algorithms is how the line
increment registers are set. The lines may be drawn using solid lines or patterned lines.
Accelerated line draw makes it possible to draw a single pixel width line between any two
points with sub pixel accuracy.
Note:The Graphics Accelerator only supports movement in the positive direction for X and Y. In
