5 / 5 page PEX 8680, PCI Express Gen 2 Switch, 80 Lanes, 20 Ports © PLX Technology, www.plxtech.com Page 5 of 5 5/14/2009, Version 1.1 Software Usage Model ExpressLane PEX 8680 RDK 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 8680 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). Interrupt Sources/Events The PEX 8680 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 8680 for hot plug events, doorbell interrupts, baseline error reporting, and advanced error reporting. Figure 10. PEX8680-16U8D BB RDK Development Tools PLX offers hardware and software tools to enable rapid customer design activity. These tools consist of a hardware module (PEX 8680 RDK), hardware documentation (available at www.plxtech.com), and a Software Development Kit (also available at www.plxtech.com). The PEX 8680 RDK (see Figure 10) is a hardware module containing the PEX 8680 which plugs right into your system. The PEX 8680 RDK can be used to test and validate customer software, or used as an evaluation vehicle for PEX 8680 features and benefits. The PEX 8680 RDK provides everything that a user needs to get their hardware and software development started. 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 8680. For more information, please refer to the PEX 8680 RDK Product Brief. Both performancePAK and visionPAK are supported by PLX’s RDK and SDK, the industry’s most advanced hardware- and software-development kits.
