At Rambus, we create cutting-edge semiconductor and IP products, spanning memory and interfaces to security, smart sensors and lighting.
The PLDA PCIe 3.1 Controller (formerly XpressRICH) is designed to achieve maximum PCI Express (PCIe) 3.1 performance with great design flexibility and ease of integration. It is fully compatible with the PCIe 3.1/3.0 specification. A PCIe 3.1 Controller with AXI (formerly XpressRICH-AXI) is also available. The controller with the Rambus PCIe 3.1 PHY forms a comprehensive interface solution delivering high-bandwidth and low-latency connectivity for demanding applications in data center, edge and graphics.
The PCIe 3.1 Controller is configurable and scalable IP designed for ASIC and FPGA implementation. It supports the PCIe 3.1/3.0 specifications, as well as the PHY Interface for PCI Express (PIPE) specification. The IP can be configured to support endpoint, root port, switch port, and dual-mode topologies, allowing for a variety of use models.
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 data path size, PIPE interface width, low power support, SR-IOV, ECC, AER, etc. for optimal throughput, latency, size and power.
The Rambus PCIe 3.1 PHY and PLDA PCIe 3.1 Controller comprise a complete PCIe 3.1 interface subsystem. The PCIe 3.1 Controller is verified using multiple PCIe VIPs and test suites, and is silicon proven in hundreds of designs in production.
The PCI Express® (PCIe) interface is the critical backbone that moves data at high bandwidth between various compute nodes such as CPUs, GPUs, FPGAs, and workload-specific accelerators. The rise of cloud-based computing and hyperscale data centers, along with high-bandwidth applications like artificial intelligence (AI) and machine learning (ML), require the new level of performance of PCI Express 5.0.
