Alveo U250 Data Center Accelerator Card

  • Lead Time: 2 weeks (for quantity of 10)

Product Description

Xilinx® Alveo™ U250 Data Center accelerator cards are designed to meet the constantly changing needs of the modern Data Center, providing up to 90X higher performance than CPUs for key workloads, including machine learning inference, video transcoding, and database search & analytics. Built on the Xilinx 16nm UltraScale™ architecture, Alveo accelerator cards are adaptable to changing acceleration requirements and algorithm standards, capable of accelerating any workload without changing hardware, and reducing 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 tools for developers to bring differentiated applications to market.

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.

Vitis Design Flow

Set Up the Alveo U250 for Deploying Applications On-Premises

Follow steps 1 and 2 for deploying or developing applications on the U250 accelerator card.


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


Download the Deployment Target Platform

The deployment target platform is the communication layer physically implemented and flashed into the card.

Develop Your Own U250 Accelerated Applications

In addition to steps 1 and 2, also follow steps 3 and 4 for development on the U250 using the Vitis design flow.


Download the Development Target Platform

The development target platform is required if you are building your own applications. Available Alveo Platforms

Note: Please select the development platform that matches the deployment platform selected in Step 2.


Download the Vitis Design Environment

The Xilinx Vitis software platform provides a framework for developing accelerated applications.
