power consumption of a GXLV processor, this solution
satisfies the needs of battery powered devices such as
National’s WebPAD™ system, a Geode GXLV proces-
sor/CS5530 based design. Also, thermal design is eased
allowing for fanless system design.
The GXLV processor’s graphics/video output is connected
to the CS5530. The CS5530 graphics/video support
includes a PLL that generates the DOT clock for the GXLV
processor (where the graphics controller is located), video
acceleration hardware, gamma RAM plus three DACs for
RGB output to CRT, and digital RGB that can be directly

Architecture Overview (Continued)
1.10 PROCESSOR SUPPORT
The traditional south bridge functionality included in the
CS5530 I/O companion chip has been designed to sup-
port the GXLV processor. When combined with the GXLV
processor, the CS5530 provides a bridge which supports
a standard ISA bus and system ROM. As part of the video
subsystem, the CS5530 provides MPEG video accelera-
tion and a digital RGB interface, to allow direct connection
to TFT LCD panels. This chip also integrates a gamma
RAM and three DACs, allowing for direct connection of a
CRT monitor. Figure 1-5 shows a typical system block dia-
gram.

nections refer to Section 3.1 “Processor Interface” on
