Architecture Overview
2.5
The Graphics Processor is based on the graphics proces-
sor used in the AMD Geode GX processor with several fea-
tures added 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. Features added to the Graphics Processor include:
• Command buffer interface
