Graphics Processor
6.3
The Graphics Processor is based on the graphics proces-
sor used in the AMD Geode™ GX processor with several
features 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
transparency, 256 ternary raster operations, alpha blenders
to support 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
• Hardware accelerated rotation BLTs
