KRIA DYNAMIC FUNCTION EXCHANGE REFERENCE DESIGNS

Introduction

This repository contains DFX example designs on Kria. The repository structure is outlined below.

• k26 - Hardware platform supported. Both KV260 and KR260 are supported.

  • 2rp_design - Top level directory containing Vivado HW design files for 2 slot DFX design.
    • rm_tcl - Directory contains tcl files for the accelerator modules("RMs") built against the base shell.
    • xdc - Directory contains design constraints
      • physical_constraints.xdc
      • timing_constraints.xdc
    • opendfx_shell.tcl - Top-level script which
      • Sources the RMs in rm_tcl directory and creates RM Block Designs(BDs)
      • Creates base shell containing Block Design containers(BDCs)
      • Adds RM BDs to BDCs
      • Creates DFx configurations.
      • Generates bitfiles for the base shell and the accelerators.
    • create_new_rm - Scripts to create new reconfigurable module for the 2RP design.
      • abstract_shells - Contains the abstract shells for slots RP_0 and RP_1.
      • generate_rm.tcl - Script to generate partial bitfiles for new accelerators.
  • 1rp_design - Top level directory containing Vivado HW design files for 1 slot DFX design.
    • rm_tcl - Directory contains tcl files for the accelerator modules("RMs") built against the base shell.
    • xdc - Directory contains design constraints
      • physical_constraints.xdc
      • timing_constraints.xdc
    • opendfx_shell.tcl - Top-level script which
      • Sources the RMs in rm_tcl directory and creates RM Block Designs(BDs)
      • Creates base shell containing Block Design containers(BDCs)
      • Adds RM BDs to BDCs
      • Creates DFx configurations.

  • Standalone
    • data - Directory to store input data and golden data for the accelerators.
    • src - Directory containing common platform files.
    • build_<RM_NAME>.tcl - Vitis script to build a RM application elf.
    • test_<RM_NAME>.tcl - Script to test the RM_NAME application on the target board.
    • Directories with accelerator name. Contains the application code specific to the accelerator.

About DFX

The AMD-Xilinx Dynamic Function eXchange (DFX) is a technology that enables an incremental and partitioned hardware configuration of a programmable device. Details on DFX capabilities within the Vivado tool are available in UG909. In PL/FPGA-based DFX this enables a concept of reconfigurable partitions (RP) and reconfigurable modules (RM). The RP provides a pre-provisioned HW space allocation within which different RMs can be loaded dynamically. The system and solution capabilities of the DFX incremental HW configuration enable:

• Partitioned designs allowing one part of the system to be changed (reconfigured) while another part of the system remains running.

• “Slotted” architecture allowing for dynamically composable HW systems without having to recompile a monolithic configuration bitstream file.

• Decoupled life cycles for PL-based functions, facilitating a reconfigurable module (RM) to be deployed to the field later without having to update or rebuild the base platform design.
