These tools consist of a hardware module (PEX 8649 RDK), hardware documentation (available at www.plxtech.com), and a Software Development Kit (also available at www.plxtech.com). ExpressLane PEX 8649 RDK The PEX 8649 RDK (see Figure 10) is a hardware module containing the PEX 8649 which plugs right into your system. The PEX 8649 RDK can be used to test and validate customer software, or used as an evaluation vehicle for PEX 8649 features and benefits. The PEX 8649 RDK provides everything that a user needs to get their hardware and software development started. Figure 9. N+1 Failover. Software Usage Model Software Development Kit (SDK) 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 8649 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’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 8649. For more information, please refer to the PEX 8649 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. Product Ordering Information Part Number Description PEX8649-AA50BC F 48-Lane, 12-Port PCI Express Switch, Pb-Free (27x27mm 2) PEX8649-16U16D AIC RDK PEX 8649 Rapid Development Kit with x16 Upstream and Two x16 Downstream Interrupt Sources/Events The PEX 8649 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 8649 for hot plug events, doorbell interrupts, baseline error reporting, and advanced error reporting. PLX Technology, Inc. All rights reserved.
