Processor Support

The traditional south bridge functionality included in the

CS5530A companion device has been designed to support

the GX1processor. When combined with a GX1 processor,

the CS5530A provides a bridge which supports a standard

ISA bus and system ROM. As part of the video subsystem,

the CS5530A provides MPEG video acceleration 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 moni-

tor. Figure 2-1 shows a typical system block diagram.

For detailed information regarding processor signal con-

nections refer to Section 4.1 "Processor Interface" on page

48.
