Graphics Processor
6.3
The Graphics Processor is based on the graphics proces-
sor used in the Geode™ GX processor with several new
features to enhance performance and functionality. Like its
predecessor, the AMD Geode™ LX processor’s Graphics
Processor is a BitBLT/vector engine that supports pattern
generation, source expansion, pattern/source transpar-
ency, 256 ternary raster operations, alpha blenders to sup-
port alpha-BLTs, incorporated BLT FIFOs, a GeodeLink™
interface and the ability to throttle BLTs according to video
timing. New features added to the Graphics Processor
include:
