bus interface (matching bus, device, and function

number).

Software Usage Model

From a system model viewpoint, each PCI Express port

is 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 virtual

PCI to PCI bridges within the PEX 8548 are compliant

to the PCI and PCI Express system models. The

Configuration Space Registers (CSRs) in a virtual

primary/secondary PCI to PCI bridge are accessible by

type 0 configuration cycles through the virtual primary

Interrupt Sources/Events

The PEX 8548 switch supports the INTx interrupt

message type (compatible with PCI 2.3 Interrupt signals)

or Message Signaled Interrupts (MSI) when enabled.

The PEX 8548 generates interrupts/messages for hot

plug events, doorbell interrupts, baseline error reporting,

and advanced error reporting.

Development Tools

ExpressLane PEX 8548 RDK

PLX offers hardware and software tools to enable rapid

customer design activity. These tools consist of a

hardware module (PEX 8548 RDK), hardware

documentation, and a Software Development Kit (SDK).

The PEX 8548 RDK hardware module includes the PEX

8548 with one x16 upstream port and two x16

downstream ports (see Figure 6). The RDK comes with

two breakout boards which allow you to split each x16

downstream slot into three (x8, x4, x4) or two (x8, x8)

separate ports. Using the breakout boards, up to 6

downstream ports can be created. The PEX 8548 RDK

board can be installed on a motherboard or used as a

riser card. The PEX 8548 RDK can be used to test and

validate customer software. Additionally, it can be used

as an evaluation vehicle for PEX 8548 features and

benefits. The PEX 8548 RDK provides everything that a

user needs to get their hardware and software

development started.
