Controller IP for 3.1/3.0 Supporting Root Port, Endpoint, Dual-mode 
Configurations, with Built-in DMA and Configurable AMBA AXI 
Interconnect 


XpressRICH-AXI™ is a configurable and scalable PCIe controller Soft IP designed
for ASIC and FPGA implementation. The XpressRICH-AXI Controller IP for PCIe 3.x
is compliant with the PCI Express 3.1/3.0 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. XpressRICH-AXI Controller
IP is verified using multiple PCIe VIPs and testsuites, and is proven in production silicon
in hundreds of designs using a variety of commercial and proprietary PCIe PHYs. PLDA
XpressRICH-AXI Controller IP for PCIe 3.1/3.0 is the #1 choice for designers requiring
enterprise-class features, highest performance, reliability, and scalability.
