General Description
Figure 1 shows a high-level block diagram of the Cyclone® V Hard IP for PCI Express block.
Figure 1 Cyclone V Hard IP for PCI Express Block Diagram
Cyclone V Hard IP for PCI Express: Cyclone V devices feature up to two implementations of hard PCIe circuitry. The hard IP can be configured as Gen1 x1 or x4 and Gen2 x1. The hard IP has an optimized application interface to help you achieve maximum effective throughput. You can parameterize the PCIe interface for various customizations to meet your specific needs. For example, there is support for a configurable payload and a configurable retry buffer, and optional support for high-reliability features, such as ECRC and AER. The Cyclone V hard IP also provides multifunction support to enable multiple endpoints to appear as a single endpoint to the root port.
