Overview

Features

The DPU has the following features:

  • One AXI slave interface for accessing configuration and status registers.
  • One AXI master interface for accessing instructions.
  • Supports configurable AXI master interface with 64 or 128 bits for accessing data depending on the target device.
  • Supports individual configuration of each channel.
  • Supports optional interrupt request generation.
  • Some highlights of DPU functionality include:
    • Configurable hardware architecture core includes: B512, B800, B1024, B1152, B1600, B2304, B3136, and B4096

  1. Linux OS and driver support information are available from DPU TRD or Vitis™ AI development kit.
  2. If the target device is Zynq-7000 SoC, see the notifications in Development Flow.
  3. For the supported tool versions, see the Vivado Design Suite User Guide: Release Notes, Installation, and Licensing (UG973).
  4. The DPU is driven by instructions generated by the Vitis AI compiler. When the target neural network (NN), DPU hardware architecture, or AXI data width is changed, the related .elf file which contains DPU instructions must be regenerated.
