2.5. About the SoC Design Example

The FPGA AI Suite SoC design example shows how the Intel® Distribution of OpenVINO™ toolkit and the FPGA AI Suite support the CPU-offload deep learning acceleration model in an embedded system

The SoC design examples are implemented with the following components:

  • FPGA AI Suite IP
  • Intel® Distribution of OpenVINO™ toolkit
  • The community-supported OpenVINO™ ARM plugin
  • Sample hardware and software systems that illustrate the use of these components
  • Arm*-Linux build scripts for the Arria® 10 SX SoC and Agilex™ 7 I-Series SoC FPGA hard processor system (HPS) built using Yocto frameworks

For an easier initial experience, these design examples include prebuilt FPGA bitstreams and a Linux-compiled system image that correspond to pre-optimized FPGA AI Suite architecture files.

You can copy this disk-image to an SD card and insert the card into a supported FPGA development kit. Additionally, you can use the design example scripts to choose from a variety of architecture files and build (or rebuild) your own bitstreams, subject to IP licensing limitations.

The following sections in this document describe the steps to build and execute the design:
The following sections in this document describe design decisions and architectural details about the design:

Use this document to help you understand how to create a SoC example design with the targeted FPGA AI Suite architecture.

SoC Design Example Execution Models

The SoC design example has two execution models:
  • Memory-to-memory (M2M) execution model, which provides a dla_benchmark interface to the inference engine, similar to the PCIe-based design examples.

    For design details, refer to [SOC] Memory-to-Memory (M2M) Variant Design.

  • Streaming-to-memory (S2M) execution model that demonstrates a streaming data source

    For simplicity in this design example, the streaming data source is the SoC ARM CPU itself, which streams to a layout transform on the FPGA, but this design illustrates one of the suggested system architectures for any streaming source.

    For design details, refer to [SOC] Streaming-to-Memory (S2M) Variant Design.

The design example is typically compiled for the S2M execution model, which supports both the M2M and S2M modes. A reduced functionality bitstream is also included as a compilation option, which supports only the M2M execution model.

The SoC design example has been optimized for simplicity, to create a flexible foundation that you can use to build more complex SoC designs.
