GEODE GXM/CS5530 SYSTEM DESIGNS

The GXm Integrated Subsystem with MMX support con-

sists of two chips, the GXm Processor and the CS5530

I/O companion. The subsystem provides high perfor-

mance using 32-bit x86 processing. The two chips inte-

grate video, audio and memory interface functions

normally performed by external hardware.

As described in separate manuals, the CS5530 enables

the full features of the GXm processor with MMX support.

These features include full VGA and VESA video, 16-bit

stereo sound, IDE interface, ISA interface, SMM power

management, and AT compatibility logic. In addition, the

newer CS5530 provides an Ultra DMA/33 interface,

MPEG2 assist, and AC97 Version 2.0 compliant audio.

Figure 1-2 shows a basic block system diagram (refer to

Figure 2-4 on page 34 for detailed subsystem intercon-

nection signals). It includes the National Semiconductor

CS9210 Dual-Scan Flat Panel Display Controller for

designs that need to interface to a DSTN panel (instead of

TFT panel).
