Rambus PCIe 2.1 Controller with AXI is a configurable and scalable PCIe controller Soft IP designed for ASIC and FPGA implementation. Rambus PCIe 2.1 Controller with AXI is compliant with the PCI Express 2.1 specifications, as well as with the PHY Interface for PCI Express (PIPE) specification and the AMBA® AXI™ Protocol Specification. The IP can be configured to support endpoint, root port, and dual-mode topologies, allowing for a variety of use models, and exposes a configurable, flexible AMBA AXI interconnect interface to the user. The provided Graphical User Interface (GUI) Wizard allows designers to tailor the IP to their exact requirements, by enabling, disabling, and adjusting a vast array of parameters, including number, type, and width of AXI interfaces, PIPE interface width, low power support, SR-IOV, ECC, AER, etc. for optimal throughput, latency, size and power. Users may optionally enable the built-in Legacy DMA engine based on the application requirements. Rambus PCIe 2.1 Controller with AXI is the #1 choice for designers requiring enterprise-class features, highest performance, reliability, and scalability.
