  • Introduction to HLS UltraFast Design Methodology
    Introduces the methodology guidelines covered in this course and
    the HLS UltraFast Design Methodology steps. {Lecture}
  • Introduction to I/O Interfaces
    Explains interfaces such as the block-level and port-level
    protocols abstracted by the Vitis HLS tool from the C design.
  • Block-Level I/O Protocols
    Explains the different types of block-level protocols abstracted by
    the Vitis HLS tool. {Lecture, Lab}

    Describes the port-level interface protocols abstracted by the Vitis
    HLS tool from the C design. {Lecture, Demo, Lab}
  • Port-Level I/O Protocols: AXI4 Interfaces
    Explains the different AXI interfaces (such as AXI4-Master,
    AXI4-Lite (Slave), and AXI4-Stream) supported by the Vitis HLS
    tool. {Lecture, Demo}
  • Port-Level I/O Protocols: Memory Interfaces
    Describes the memory interface port-level protocols (such as
    block RAM and FIFO) abstracted by the Vitis HLS tool from the C
    design. {Lecture, Lab}
  • Pipeline for Performance: PIPELINE
    Describes the PIPELINE directive for improving the throughput of
    a design. {Lecture, Lab}

Day 2

  • Pipeline for Performance: DATAFLOW
