Alveo U50 Data Center Accelerator Card


Product Description

The Xilinx® Alveo™ U50 Data Center accelerator cards provide optimized acceleration for workloads in financial computing, machine learning, computational storage, and data search and analytics. Built on Xilinx UltraScale+ architecture and packaged up in an efficient 75-watt, small form factor, and armed with 100 Gbps networking I/O, PCIe Gen4, and HBM, Alveo U50 is designed for deployment in any server.

Alveo accelerator cards are adaptable to changing acceleration requirements and algorithm standards, capable of accelerating any workload without changing hardware, and reduce overall cost of ownership.

Enabling Alveo accelerator cards is an ecosystem of Xilinx and partner applications for common Data Center workloads. For custom solutions, Xilinx’s Application Developer Tool Suite (Vitis™ environment) and Machine Learning Suite provide the frameworks for developers to bring differentiated applications to market.

The Alveo Programmable Cable is required for development access on Alveo U50 cards. The cable provides micro-USB support from a host PC to the Alveo U50 maintenance connector.

The preferred optimal design flow for targeting the Alveo Data Center accelerator card uses the Vitis™ software platform. Steps to deploy and develop using Vitis are given below. Long-time FPGA designers might want to use traditional design flows, such as RTL or HLx. This flow does not require installing the Vitis platform.

Set Up the Alveo U50 for Deploying Applications On-Premises

To install the Alveo card and deploy applications, follow the instructions in the Card Install Guide.  Download links for the Xilinx Runtime and Deployment Target Platform, needed during card installation, are given below.


Download the Xilinx Runtime

The Xilinx runtime (XRT) is a low level communication layer (APIs and drivers) between the host and the card.

IMPORTANT: Please enter the following command before installing the XRT: 


sudo yum-config-manager --enable rhel-7-server-optional-rpms

sudo yum install -y


sudo yum install epel-release

Develop Your Own U50 Accelerated Applications

To develop Alveo accelerated applications, follow the software installation instructions in the Vitis Development Installation Guide. The Vitis design environment and development target platform download links are given below.
