Controller IP for PCIe 4.0, 3.1/3.0 Supporting Root Port, Endpoint,
Dual-mode Configurations, with Multi-Channel 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 4.0 is
compliant with the PCI Express 4.0, and 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 a built-in
DMA engine for handling data transfers between the PCIe domain and the AXI domain.
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 4.0 is the #1 choice
for ASIC, SoC and FPGA designers looking for an enterprise-class PCIe interface solution
with a high-performance, reliable, and scalable AMBA 3 AXI/AMBA 4 AXI interconnect.
