PXI and Hybrid Slots Ensure Compatibility
{"Image DocumentName": "PXI and Hybrid Slots Ensure Compatibility", "Image ImageDescription": "The first PXI Express chassis will provide PXI peripheral slots. Additionally, by taking advantage of the available pins on the high-density PXI backplane, the PXI Express hybrid slots are capable of delivering signals for both PCI and PCI Express. In doing so, these PXI Express hybrid slots provide backward compatibility that is not available with desktop PC card-edge connectors, where a single slot cannot support both PCI and PCI Express signaling. Thus, the hybrid slot allows you to install a PXI module that uses PCI signaling or a future high-performance PXI Express module that uses PCI Express signaling. In addition to providing hardware compatibility through hybrid slots, PXI Express systems also provide software compatibility so that engineers can preserve their investment in existing software. PCI Express software compatibility is guaranteed through the PCI Special Interest Group (PCI-SIG) which includes companies like Intel and Dell. Because PCI Express uses the same driver and OS model as PCI, the specification guarantees that engineers have complete software compatibility among PCI-based systems, for example PXI, and PCI Express-based systems, such as PXI Express. As a result, both vendors and customers do not need to change driver or application software for PCI Express-based systems. By maintaining software compatibility between PCI and PCI Express technology, the specification drastically reduces cost for vendors and integrators to insert new PCI Express technology into existing test systems. With hardware compatibility provided by the hybrid slot and software compatibility, the cost of adding PXI Express technology is minimal.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
