AI SDK Contents:

eSD Card Image

• • The eSD Card Image is a prebuilt yocto image that contains the following yocto packages
    • VLP Linux
    • ARM Mali Graphics ( limited license )
    • Codec ( limited license )
    • DRP-AI Driver
    • OpenCVA ( DRP Accelerated )
•  
  • The eSD Image DOES NOT include the following
    • e-CON MIPI Camera ( Contact e-CON Systems )
    • AI SDK Demos ( Coming Soon )

TVM Translator Environment

• • The TVM Translator is the recommended translator to translate AI models for the DRP-AI Driver. All the AI SDK demos use the TVM Translator. Included in the AI SDK is the DRP-AI Translator. This translator is needed for TVM installation and does not need to be installed. Installation using Docker is recommended because the TVM Environment requires a PC running Ubuntu 20.04. For information about Docker setup see here.
  • For information about using the TVM Translator see the Official Site here.
  • NOTE: Once the AI SDK Environment is setup the TVM will be installed in the the root directory /drp_tvm_sdk

Available Demos

DRP-AI

• vSLAM (Contact Sales Representative for demo)

• DRP-AI Demos
  • Included with the DRP-AI Package. AI models include
    • Classification (Resnet50)
    • Object Detection ( YoloX and Yolov2 )
    • Segmentation ( DeepLabv2 )
• Renesas RZ/V2H AI SDK

AI SDK Application Repository

The AI SDK repository contains many AI Demos. This repo contains source, pre-compiled application, and Translated AI Models for DRP-AI. This make the repository very large. Below is a method to download single demo

git clone --depth 1 --filter=blob:none --sparse \
  https://github.com/renesas-rz/rzv_ai_sdk.git
cd test-git-partial-clone-big-small
git sparse-checkout set R01_object_detection

RZ/V2H vSLAM Sample Code 

• This is a YOLO-Planar-SLAM-DRP system developed based on YoloPlanarSLAM.
  This SLAM can improve tracking accuracy by removing moving object (human) with object detection AI model (YOLO).
  Renesas' high-performance AI accelerator (DRP-AI) enable to operate YOLO in real-time.

DRP-AI Tools

AI Model to DRP-AI Hardware Translation Flow. For Sparse Model Creation the recommended path after ML Framework is S1, S2, S3. For Dense Model Creation after ML Framework is D1, D2.

⚠️ The DRP-AI Tools will only work in Ubuntu 20.04

⚠️ the flow S1 is using the pruning CLI tool. The Pruning tool also includes python expansion pack, so S1 can be integrated into the ML Framework training step.

(S1) RZ/V2H Expansion Pack (Pruning Tool )

The DRP-AI MAC supports sparse arrays (unstructured pruning). The expansion pack includes CLI and python libraries (expansion pack). The expansion pack allows for integration of the Pruning process into the ML Frameworks for training. The Expansion Pack supports Pytorch, Tensorflow, and Tensorflow-lite.

DRP-AI Application Development

The Renesas TVM is the DRP-AI translator tool that converts standard ML Frameworks ( Pytorch, Tensorflow, ONNX, .. ) to DRP-AI Hardware object files. The TVM for RZ/V2H includes the following tools. This is the recommended tool for AI Model Translation to the DRP-AI.

• Inference Pre-processing Configuration
• Quantization Tool
• Translation Compiler

RZ/V2H DRP-AI Translator and Quantization Tool

Official Site

This tool is used by the TVM for translation of AI Models. It is needed to to install the TVM. ( AI SDK includes this )

For Advance Translation this tool can also be used for AI Model translation instead of the Renesas TVM. Only AI Model operations listed in the RZ\V2H DRP-AI Translator Manual ( section 4.1) can be used with this translator. For AI models that have un-supported operations please use the Renesas DRP-AI TVM Tool. The tool supports quantization and translation of AI Models exported in the ONNX format to the RZ/V2H DRP-AI (INT8) hardware. This tool includes the following

• RZ/V2H DRP-AI Translator
• DRP-AI Quantization Tool

The RZV2H DRP-AI MAC only performs INT8 operations, so AI Models must be quantized before translation.

Retraining Quantized Models

It is recommended to retrains a model after quantization to reduce changes to the inference accuracy . For that purpose the Quantization tool includes optional parameters that point to the data set and dataset parsing function.

Beside the AI Model below are additional items needed to properly quantize a model.

• Customer Dataset ( does not need to be the full dataset )
• Function to parse the mode

Image Processing

OpenCV

• By default OpenCV is included AI SDK.
• OpenCV Version 4.1
• DRP Acceleration
  • OpenCV DRP Acceleration uses the RZ/V2H DRP ( not DRP-AI ) hardware IP
    • Accelerated OpenCV functions: TBD
  • Released : TBD
  • Uses the DRP ( not DRP-AI ) hardware IP
