Software Usage Model

Development Tools

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 8632 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

bus interface (matching bus number, device number, and

function number).

PLX offers hardware and software tools to enable rapid

customer design activity. These tools consist of a

hardware module (PEX 8632RDK), hardware

documentation (available at www.plxtech.com), and a

Software Development Kit (also available at

www.plxtech.com).

ExpressLane PEX 8632RDK

The PEX 8632RDK is a hardware module containing the

PEX 8632 which plugs right into your system. The

PEX 8632RDK can be used to test and validate customer

software, or used as an evaluation vehicle for PEX 8632

features and benefits. The PEX 8632RDK provides

everything that a user needs to get their hardware and

software development started.

Interrupt Sources/Events

The PEX 8632 switch supports the INTx interrupt

message type (compatible with PCI 2.3 Interrupt signals)

or Message Signaled Interrupts (MSI) when enabled.

Interrupts/messages are generated by PEX 8632 for hot

plug events, doorbell interrupts, baseline error reporting,

and advanced error reporting.

Software Development Kit (SDK)

PLX’s Software Development Kit is available for

download at www.plxtech.com/sdk. The software

development kit includes drivers, source code, and GUI

interfaces to aid in configuring and debugging the

PEX 8632.
