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 8532 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
Development Tools
PLX is offering hardware and software tools (PEX 8532
RDK) to enable rapid customer design activity. These tools
are bundled in a Rapid Development Kit (RDK). The RDK
consists of hardware, hardware documentation and Software
Development Kit (SDK).
primary bus interface (matching bus number, device number,
and function number).
Interrupt Sources/Events
The ExpressLane PEX 8532 switch support 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 8532 for hot plug
events, baseline error reporting, and advanced error reporting.

PEX 8532 RDK
The RDK hardware module includes the PEX 8532 with a x16
upstream port, a x8 downstream port and two x4 downstream
ports. The upstream port is a x16 PCI Express edge connector.
PLX offers adapters (x8, x4, and x1) which can be used to
plug the RDK in smaller slots.
The PEX 8532 RDK board can be installed on a motherboard,
used as a riser card, or configured as a bench-top board. The
PEX 8532 RDK can be used to test and validate customer
software. Additionally, it can be used as an evaluation vehicle
for the PEX 8532 features and benefits.
SDK
The SDK tool set includes:
-
Linux and Windows drivers
-
C/C++ Source code, Objects, libraries
-
User’s Guides, Application examples, Tutorials
