11 / 241 page Revision 4.1 11 www.national.com 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. For detailed information regarding processor signal con- nections refer to Section 3.1 “Processor Interface” on page 41. Figure 1-5.
