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 8648 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 8648RDK), hardware documentation (available at www.plxtech.com ), and a Software Development Kit (also available at www.plxtech.com). ExpressLane PEX 8648RDK The PEX 8648RDK is a hardware module containing the PEX 8648 which plugs right into your system. The PEX 8648RDK can be used to test and validate customer software, or used as an evaluation vehicle for PEX 8648 features and benefits. The PEX 8648RDK provides everything that a user needs to get their hardware and software development started. Interrupt Sources/Events The PEX 8648 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 8648 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 8648.
