6 / 241 page www.national.com 6 Revision 4.1 1.0 Architecture Overview The Geode CS5530 can be described as providing the functional blocks shown in Figure 1-1. • PCI bus master/slave interface • ISA bus interface • AT compatibility logic • IDE controllers • Power management -GPIO interfaces - Traps, Events, Timers • Joystick/Game Port interface • Virtual audio support hardware • Video display, which includes MPEG accelerator, RAMDAC, and video ports •USB controllers For CPU interface connection refer to Figure 1-5 on page 11. 1.1 PCI BUS INTERFACE The CS5530 provides a PCI bus interface that is both a slave for PCI cycles initiated by the CPU or other PCI master devices, and a non-preemptable master for DMA transfer cycles. The chip also is a standard PCI master for the IDE controllers and audio I/O logic. The CS5530 sup- ports positive decode for configurable memory and I/O regions and implements a subtractive decode option for unclaimed PCI accesses. The CS5530 also generates address and data parity and performs parity checking. The CS5530 does not include the PCI bus arbiter, it is locatedinthe processor. Configuration registers are accessed through the PCI interface using the PCI Bus Type 1 configuration mecha- nism as described in the PCI 2.1 Specification. Figure 1-1.
