PCI Express (PCIe) is a general purpose serial interconnect that can be leveraged for Communications, Data-center, Embedded, Test & Measurements, Military and Desktop applications. It can also be used as peripheral device interconnect, chip-to-chip interface and bridge to many other protocol standards.
Xilinx provides high performance and low power integrated hard block PCIe solution in Xilinx All Programmable devices at no extra cost. Xilinx also provides soft blocks, boards, connectivity kits, reference designs, drivers and tools to further enhance user experience in implementing PCIe based designs.
New in the UltraScale+ Portfolio
Xilinx 16nm UltraScale+ devices integrate many essential features required with PCI Express in today’s data center and embedded applications.
- DMA solutions (DMA for PCI Express Subsystem) used for low latency and high performance data transfers with host
- Physical/Virtual Functions required for Single Root IO Virtualization (SR-IOV) to share IO resources over single PCIe link
- Native Gen3x16 and Gen4x8 width Integrated PCIe block for 100G applications
- Additional tags to support more read requests enabling overall system performance
