It provides mezzanine. All 64 bits of PMC I/O are routed to the multi-host systems two functions to accomplish this: a PCI Express VPX backplane connector. • Supports PMC or XMC modules switch, and a mezzanine carrier. Alternatively, the PEX430 can be configured • Mezzanine I/O routed to VPX backplane The PCI Express switch of the PEX430 allows up to to carry an XMC card, with eight lanes of PCI • Air-cooled and rugged conduction four ports of 4-lane PCI Express to be connected Express routed from the PCI Express switch to -cooled variants to a non-blocking line-speed switch, such that the mezzanine size. For mezzanines that require a scalable, complex system architecture can be the full eight lanes of bandwidth, the PEX430 can created. In order to support systems requiring be configured for 8-lane PCI Express at the VPX interconnection of more than four hosts, multiple backplane connector. All 64 bits of XMC I/O are PEX430 boards may be daisy-chained together. routed to the VPX backplane connector. The switch supports non-transparent bridging From a software perspective, each PCI Express mode, allowing multiple intelligent hosts to be port is a virtual PCI-to-PCI bridge device, with its connected together. Non-transparent bridges own set of PCI Express configuration registers. allow systems to isolate memory domains by The host can configure the other ports by way presenting the processor subsystem as an of the upstream port, using conventional PCI endpoint, rather than another memory system. enumeration. The virtual PCI-to-PCI bridges within To facilitate inter-processor communication, base the PEX4301 are compliant with the PCI and PCI address registers (BARs) are used to translate Express system models. addresses, doorbell registers are used to transmit interrupts between the address domains, and scratchpad registers are accessible from both address domains. The switch supports transparent bridging mode in order to expand the I/O capability of the VPX single board computers. A broad range of PMC and XMC daughterboards exists to provide a variety of I/O functionality.
