Software Usage Model

From a system model viewpoint, the PEX 8311 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 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).

Interrupt Sources/Events

The PEX 8311 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 8311 for hot

plug events, and baseline error reporting.

Development Tools

PLX is offering hardware and software tools to enable

rapid customer design activity. These tools include the

hardware Rapid Development Kit (PEX 8311 RDK)

shown in Figure 6 and the Software Development Kit

(SDK).

The RDK hardware module includes the PEX 8311 with

a x1 port connected to a male-edge connector, and a

Generic Local Bus port with support for non-multiplexed

“C” and multiplexed “J” modes. SBSRAM, CPLD

components are included with a Prototyping area. The

board includes a mid-bus PCIe probe interface and a

reset for PCIe. Support for all DMA methods including

block mode, scatter-gather, and ring management along

with Direct Slave is supported. JTAG provides down-

loading of code to the CPLD. An external 100 MHz

differential reference clock can be provided at the card

edge connector or from the slot.

The PEX 8311RDK can be installed in a motherboard,

used as a riser card, or configured as a bench-top board.

The PEX 8311RDK can be used to test and validate

customer software. Additionally, it can be used as an

evaluation vehicle for the PEX 8311 features and

benefits.

SDK

The SDK tool set includes:

- Linux & Windows NT/98/2000/Me/XP/2003 server drivers

- C/C++ Source code, Objects, and libraries
