The PEX 8732 RDK (see Figure 10) is a hardware module

containing the PEX 8732 which plugs right into your

system. The PEX 8732 RDK can be used to test and

validate customer software, or used as an evaluation

vehicle for PEX 8732 features and benefits. The PEX 8732

RDK provides everything that a user needs to get their

hardware and software development started.

From a system model

a virtual PCI to PCI bridge device and has its own set of

PCI Express configuration registers. It is through the

upstream port that the BIOS or host can configure the

other ports using standard PCI enumeration. The virtua

PCI to PCI bridges within the PEX 8732 are compliant to

the PCI and PCI Express system models. The

Configuration Space Registers (CSRs) in a virt

primary/secondary PCI to PCI bridge are accessible

type 0 configuration cycles through the virtual primary b

interface (matching bus number, device number, and

function number).
