• Additional blocks available for both AI Engines and HDL:
  • AIE, AIE-ML, AIE-ML v2
    • New: Function Approximation
    • New: Correlation/Convolution
    • New: Cumulative Sum
  • HDL Library Blocks
    • Enhanced: FFT (Added native floating-point SSR = 32, 64)
    • Enhanced: FIR (Support fractional rate interpolation with SSR)

Updates for Vitis IDE for Embedded Development

• Python API for Updating Building Configuration 
• Run Vitis™ API in Python Environment 
• PS Trace Visible by Default for Supported Cores
• Debug Enhancement – Updated values are now highlighted in Watch View and Register view
• Cancel or Terminate Backend Tasks
• Unified Platform BSP File Paths (Linux® & Windows®)

To install Vitis Core Development Kit, select Vitis on the Unified Installer. Vitis installation includes Vivado™ Design Suite, Vitis Model Composer, Vitis HLS.

There is no need to install Vivado separately.

Important Information

The Vitis™ Embedded Development is a standalone embedded software development package for creating, building, debugging, optimizing, and downloading software applications for AMD FPGA processors. It includes a new Vitis IDE  with its new backend Vitis Server, as well as the classic command line utilities such as hw_server, bootgen and program_flash.

Note: This release supports Versal™, Zynq™ MPSoC, Zynq 7000 and MicroBlaze™.
