Vitis™ Unified Software Platform Overview


Software Development Platform Overview Block Diagram

The Vitis unified software platform includes:

  • Comprehensive core development kit to seamlessly build accelerated applications
  • Rich set of hardware-accelerated open-source libraries optimized for Xilinx FPGA and Versal ACAP hardware platforms
  • Plug-in domain-specific development environments enabling development directly in familiar, higher-level frameworks
  • Growing ecosystem of hardware-accelerated partner libraries and pre-built applications
  • Vitis Model Composer, a Model-Based Design tool that enables rapid design exploration and verification within the MathWorks MATLAB® and Simulink® environment and accelerates the path to production on Xilinx devices. 
  • Vitis Networking P4 allows for the creation of soft-defined networks. VitisNetP4 data plane builder generates systems that can be programmed for a wide range of packet processing functions from simple packet classification to complex packet editing.

Platform-Based Flow

The Vitis development enables portability from platform to platform whether you are porting from PoC, development board, or custom board.

Vitis Platform-Based design methodology provides many productivity advantages.

  1. Platform Reuse: Swap different acceleration applications with the same platform.
  2. Application Portable: Port applications across different platforms with minimum efforts
  3. Simulation Time: Speed up co-simulation with Kernels
  4. Run Time: Open source runtime that takes care of host-device communication through PCIe or embedded for you
  5. System debug: Save the full hardware compile by co-simulating the full system


Platform-Based Flow Enables Portability & Reuse

Vitis Accelerated Libraries

Open-source, performance-optimized libraries that offer out-of-the-box acceleration with minimal to zero-code changes to your existing applications, written in C, C++ or Python. Leverage the domain-specific accelerated libraries as-is, modify to suit your requirements or use as algorithmic building blocks in your custom accelerators.

Vitis Core Development Kit

Complete set of graphical and command-line developer tools that include the Vitis compilers, analyzers and debuggers to build, analyze performance bottlenecks and debug accelerated algorithms, developed in C, C++ or OpenCL. Leverage these features within your own IDEs or use the standalone Vitis IDE.

Xilinx Runtime library

Xilinx Runtime library (XRT) facilitates communication between your application code (running on an embedded ARM or x86 Host) and the accelerators deployed on the reconfigurable portion of PCIe based Xilinx accelerator cards, MPSoC based embedded platforms or ACAPs. It includes user-space libraries and APIs, kernel drivers, board utilities, and firmware.

Vitis Target Platforms Diagram

Vitis Target Platforms

The Vitis target platform defines base hardware and software architecture and application context for Xilinx platforms, including external memory interfaces, custom input/output interfaces and software runtime.

  • For Xilinx accelerator cards on-premise or in the cloud, the Vitis target platform automatically configures the PCIe interfaces that connect and manage communication between your FPGA accelerators and x86 Application code – you don’t need to implement any connection details!
  • For Xilinx embedded devices, the Vitis target platform also includes the operating system for the processor on the platform, boot loader and drivers for platform peripherals, and root file system. You can use predefined Vitis target platforms for Xilinx evaluation boards or define your own in Vivado® Design Suite.

The Vitis Model Composer is a Xilinx toolbox for MATLAB® and Simulink® enabling rapid design exploration and verification within the MATLAB® and Simulink® environment and accelerates the path to production on Xilinx devices.

  • Create a design using optimized blocks targeting AI Engines and Programmable Logic. Visualize and analyze simulation results and compare the output to golden references generated using MATLAB® and Simulink®.
  • Seamlessly co-simulation AI Engine and Programmable Logic (HLS, HDL) blocks. 
  • Automatically generate code (AI Engines dataflow graph, RTL, HLS C++) and test bench for a design.

Development Flows

Using Vitis™ Software for Application Acceleration Development Flows

Design accelerators for your data and compute-intensive applications at the edge, on-premise or in the cloud:

  1. Identify the performance-critical portions of your application that demands acceleration.
  2. Design Accelerators using Vitis Accelerated libraries or develop your own in C,C++, OpenCL or RTL.
  3. Build, Analyze and Debug to verify functional correctness and validate performance goals are met.
  4. Deploy Accelerated Application on Xilinx Platforms at edge, on-premise or cloud.

Acceleration Kernels

Vitis supports hardware acceleration kernels with PS or x86 to control kernels. The Vitis application acceleration development flow provides a framework for developing and delivering FPGA-accelerated applications using standard programming languages for both software and hardware components. For kernel creation, users can choose from the following:

  • Writing traditional RTL for PL kernel
  • C/C++ coding with Vitis HLS for PL kernel
  • Vitis model composer for PL and/or AI Engine
  • And C/C++ coding with AI Engine compiler for AI Engine

Vitis also supports hardware acceleration kernels without PS, or x86 to control for free-running. Free-running kernels have no control signal ports, and cannot be started or stopped. The "no-control signal" feature of the free-running kernel results in the following characteristics:

  • The free-running kernel has no memory input or output port, therefore it interacts with the host or other kernels (other kernels can be regular kernel or another free-running kernel) only through streams.
  • When the FPGA is programmed by the binary container (xclbin), the free-running kernel starts running on the FPGA, and therefore it does not need the clEnqueueTask command from the host code.
  • The kernel works on the stream data as soon as it starts receiving from the host or other kernels, and it stalls when the data is not available.

Using Vitis Software for Embedded Software Development Flows

Vitis core development kit includes comprehensive developer tools to design, debug, and deploy software applications targeted towards embedded processors on Xilinx Zynq, MPSoC, RFSoC, and ACAP devices. Vitis embedded software development features include:

  • Importing target platform definition created using Vivado® Design Suite
  • Application development for single, multi-processor and heterogenous processor systems
  • Ability to create and configure board support packages (BSPs) for third-party OS
  • Board bring-up and Firmware development
  • System-level performance analysis and benchmarking
  • Real-time debug and trace of heterogeneous embedded systems

Edge Deployment

As the data being produced continues to explode, there's a growing need to be able to bring computing power closer to the source of the data to meet the response-time, power-consumption and cost goals of performance-critical applications like IIoT, Automated Driving, Medical Imaging, Surveillance among others.

Xilinx embedded platforms are enabling applications where differentiation is key, power efficiency is critical, systems must be extremely responsive, and the latest algorithms and sensors need to be quickly deployed.
