PCI Express (PCIe*) protocol is a high-performance, scalable, and feature-rich serial protocol with data transfer rates from 2.5 gigatransfers per second (GT/s) to 32 GT/s and beyond. Intel® FPGA Intellectual Property (IP) for PCIe continues to scale as the PCI-SIG organization delivers next-generation specifications. Intel has been a member of PCI-SIG since 1992, and with each new generation of silicon, Intel continues to participate in PCI-SIG Compliance Workshops to ensure interoperability and conformance with current industry standards.
The PCIe IP solutions include Intel’s PCIe hardened protocol stack, which includes the transaction and data link layers, as well as a hardened physical layer. The later one includes both the physical medium attachment (PMA) and physical coding sublayer (PCS). Intel's PCIe IP portfolio also includes optional soft IP blocks, such as Direct Memory Access (DMA) engines and PCIe Switch. This unique combination of hardened and soft IP provides superior performance and flexibility for optimal integration.
Intel offers Intel FPGA® IP function-based PCIe IP solutions that have evolved with PCI-SIG’s protocol roadmap.
